General Safety Precautions
Materials testing systems are potentially hazardous.
Materials testing involves inherent hazards from high forces, rapid motions and stored
energy. You must be aware of all moving and operating components that are potentially hazardous, particularly the actuator in a servohydraulic testing system or the
moving crosshead in an electromechanical testing system.
Whenever you consider that safety is compromised, press the Emergency Stop button
to stop the test and isolate the testing system from hydraulic or electrical power.
Carefully read all relevant manuals and observe all Warnings and Cautions. The term
Warning is used where a hazard may lead to injury or death. The term Caution is used
where a hazard may lead to damage to equipment or to loss of data.
Ensure that the test set-up and the actual test you will be using on materials, assemblies or structures constitutes no hazard to yourself or others. Make full use of all
mechanical and electronic limits features. These are supplied to enable you to prevent
movement of the actuator piston or the moving crosshead beyond desired regions of
operation. Limits provide protection for your specimen and machine and reduce
potential hazard.
The following pages detail various general warnings that you must heed at all times
while using materials testing equipment. You will find more specific Warnings and
Cautions in the text whenever a potential hazard exists.
Your best safety precautions are to obtain training in the testing equipment that you
are using and to read your Operating Instructions and Reference Manual(s) to gain a
thorough understanding of that equipment.

Warnings
Hazard - Protect electrical cables from damage and inadvertent
disconnection.
The loss of controlling and feedback signals that can result from a disconnected or
damaged cable causes an open loop condition that may drive the actuator or crosshead
rapidly to its extremes of motion. Protect all electrical cables, particularly transducer
cables, from damage. Never route cables across the floor without protection, nor suspend cables overhead under excessive strain. Use padding to avoid chafing where
cables are routed around corners or through wall openings.
High/Low Temperature Hazard - Wear protective clothing when handling
equipment at extremes of temperature.
Materials testing is often carried out at non-ambient temperatures using ovens, furnaces or cryogenic chambers. Extreme temperature means an operating temperature
exceeding 60 °C (140 °F) or below 0 °C (32 °F). You must use protective clothing,
such as gloves, when handling equipment at these temperatures. Display a warning
notice concerning low or high temperature operation whenever temperature control
equipment is in use. You should note that the hazard from extreme temperature can
extend beyond the immediate area of the test.
Crush Hazard - Take care when installing or removing a specimen, assembly
or structure.
Installation or removal of a specimen, assembly or structure involves working inside
the hazard area between the grips or fixtures. Keep clear of the jaws of a grip or fixture
at all times. Keep clear of the hazard area between the grips or fixtures during actuator
or crosshead movement. Ensure that all actuator or crosshead movements necessary
for installation or removal are slow and, where possible, at a low force setting.
Hazard - Do not place a testing system off-line from computer control
without first ensuring that no actuator or crosshead movement will occur
upon transfer to manual control.
The actuator or crosshead will immediately respond to manual control settings when
the system is placed off-line from computer control. Before transferring to manual
control, make sure that the control settings are such that unexpected actuator or crosshead movement cannot occur.

Warnings
Robotic Motion Hazard - Keep clear of the operating envelope of a robotic
device unless the device is de-activated.
The robot in an automated testing system presents a hazard because its movements are
hard to predict. The robot can go instantly from a waiting state to high speed operation
in several axes of motion. During system operation, keep away from the operating
envelope of the robot. De-activate the robot before entering the envelope for any purpose, such as reloading the specimen magazine.
Hazard - Set the appropriate limits before performing loop tuning or running
waveforms or tests.
Limits are included within your testing system to provide a safe way of limiting actuator movement. Failure to set these limits appropriately could result in injury to personnel or damage to equipment.
Electrical Hazard - Disconnect the electrical power supply before removing
the covers to electrical equipment.
Disconnect equipment from the electrical power supply before removing any electrical safety covers or replacing fuses. Do not reconnect the power source while the covers are removed. Refit covers as soon as possible.
Rotating Machinery Hazard - Disconnect power supplies before removing
the covers to rotating machinery.
Disconnect equipment from all power supplies before removing any cover which
gives access to rotating machinery. Do not reconnect any power supply while the covers are removed unless you are specifically instructed to do so in the manual. If the
equipment needs to be operated to perform maintenance tasks with the covers
removed, ensure that all loose clothing, long hair, etc. is tied back. Refit covers as
soon as possible.
Hazard - Shut down the hydraulic power supply and discharge hydraulic
pressure before disconnection of any hydraulic fluid coupling.
Do not disconnect any hydraulic coupling without first shutting down the hydraulic
power supply and discharging stored pressure to zero. Tie down or otherwise secure
all pressurized hoses to prevent movement during system operation and to prevent the
hose from whipping about in the event of a rupture.

Warnings
Hazard - Shut off the supply of compressed gas and discharge residual gas
pressure before you disconnect any compressed gas coupling.
Do not release gas connections without first disconnecting the gas supply and discharging any residual pressure to zero.
Explosion Hazard - Wear eye protection and use protective shields or
screens whenever any possibility exists of a hazard from the failure of a
specimen, assembly or structure under test.
Wear eye protection and use protective shields or screens whenever a risk of injury to
operators and observers exists from the failure of a test specimen, assembly or structure, particularly where explosive disintegration may occur. Due to the wide range of
specimen materials, assemblies or structures that may be tested, any hazard resulting
from the failure of a test specimen, assembly or structure is entirely the responsibility
of the owner and the user of the equipment.
Hazard - Ensure components of the loadstring are correctly preloaded to
minimize the risk of fatigue failure.
Dynamic systems, especially where load reversals through zero are occurring, are at
risk of fatigue cracks developing if components of the loadstring are not correctly preloaded to one another. Apply the specified torque to all loadstring fasteners and the
correct setting to wedge washers or spiral washers. Visually inspect highly stressed
components such as grips and threaded adapters prior to every fatigue test for signs of
wear or fatigue damage.

Responsibilities
Outline
The purpose of this chapter is to detail the responsibilities of both the customer
and Instron to ensure that the proposed testing area is suitable for the installation
and operation of the testing system.
2-1
Customer Responsibilities
M21-28800-70
Customer Responsibilities
It is the responsibility of the customer to ensure that all required support services
are available, and that all necessary checks are made to allow the correct
installation of the testing system.
These services and checks are detailed in this chapter.
Site Plan
A site plan must be available, which indicates the proposed positioning of the load
frame and control console. A copy of the site plan should be sent to the Instron
Area Office in advance.
Three-Phase Power Supply
The hydraulic power supply requires a three-phase supply of 220V, 380/420V or
460V, at either 50Hz or 60Hz as specified for the type of power supply ordered.
Note:
Different pump motors are used for 50 Hz and 60Hz supplies — the frequency is
not variable.
The supply should be terminated with a suitably-rated, lockable, fused isolator as
near as possible to the hydraulic power supply, and with access to adequate
earthing terminations. This must still be accessible once the hydraulic power
supply has been installed. Refer to Chapter 5, Essential Services, for details of the
earthing requirements. The electrical connection to the hydraulic power supply
must be of flexible sheathed cable, chosen to suit local regulations to be supplied
by the customer.
Single-Phase Power Supply
Single phase power point, 230 V ±10% at 50 Hz, or 115 V ±10% at 50/60Hz as
required, must be available for mains supply to the load frame, and for general
use.
Water Supply
If you require a water-cooled hydraulic power supply, a water supply must be
available, together with sufficient piping. Chapter 5, Essential Services, details the
water supply rate, quality and temperature requirements for the various types of
pump.
2-2
Customer Responsibilities
Ventilation
Responsibilities
If you require an air-cooled hydraulic power supply, then adequate ventilation is
essential. Chapter 5 details the ventilation requirements for the various types of
hydraulic pump.
Air blast coolers are available if necessary.
Floor Loading
The site floor should be checked for weight loading. The local architect or
flooring specialist should be consulted.
The maximum weights of the load frames and console are given in Chapter 3,
Specifications. Remember that in high performance installations large dynamic
loadings may occur, thus the load capacity should be in excess of three times the
combined weight of the system and operator.
Cyclic and shock loads may require the use of anti-vibration mountings.
Noise Suppression
When siting the hydraulic power supply, consideration should be given to the
noise emission level. It is usually more convenient if the hydraulic pump is sited
in a separate room adjacent to the operating location. If special rooms have to be
built, materials suitable for sound insulation should be used. Chapter 5, Essential
Services, details the noise emission levels for the various types of hydraulic power
supply.
Cable Specification
The local electricity supply authority should be consulted for advice on cable
specifications, with consideration being given to motor start up current surges.
Chapter 5, Essential Services, gives advice on maximum current levels for various
types of hydraulic power supply.
Pipe Runs
All hydraulic pipe runs must be clean to Thermal Control Class 2 (U.K.) or ISO
Solid Contaminant Code 13/10 (U.S.A.) or NAS Class 4. Details of the required
standard are given in all individual hydraulic power supply manuals.
All pipe runs should be tested to the following pressures:
•
Pressure line — 560bar (8000psi)
2-3
Customer Responsibilities
•
Return line — 140bar (2000psi)
•
Drain line — 20 bar (150 psi)
M21-28800-70
Cleanliness and pressure checks should be carried out immediately before
installation is started. It should be noted that higher proof pressure may be
required to meet local standard practice, or the demands of the customer’s
insurers.
When the hydraulic pump is to be situated at a distance greater than 6metres from
the load frame, steel pipe runs should be provided. Refer to Chapter 5, Essential
Services, for details of the requirements for drain line bore and maximum pipe run
length. Instron can supply the flexible pipes for both ends of the pipe run in either
3 or 6 metre lengths.
Where steel pipes are used, it will be necessary to clamp the pipe to avoid excess
noise and vibration, especially when operating the testing system with large
actuator excursion. The pipes should be clamped firmly in rubber cushion blocks.
Hoses must have adequate packing to avoid chafing and must be firmly supported
by clamps when routed other than along the floor.
Handling
Unless specifically arranged otherwise, it is the customer’s responsibility to
arrange for off-loading, unpacking and moving the testing system to the final
operating location. This includes insurance and safety responsibilities.
2-4
Instron Responsibilities
The equipment and services provided by Instron as part of the contract to supply
the 8800 Series Testing System are as given below. Where special conditions
apply, the corresponding equipment and services should be the subject of a
separate and specific quotation.
Insurance
Instron will provide insurance cover from the manufacturing site in the U.K. to the
customer’s premises in the U.K.. In the U.S.A. insurance cover from the
manufacturing site to the customer’s premises is usually the responsibility of the
carrier. Outside of these areas all purchase orders must indicate specifically which
party is to effect marine insurance cover. In the absence of this indication, Instron
will arrange insurance cover at the customer’s expense.
Handling
On arrival at the customer’s premises, Instron will, upon special request, supervise
the off-loading and transportation onto the site, this being a special condition as
mentioned above.
Installation
Once components are on the site and in position, Instron will be responsible for
making all electrical and hydraulic connections between the load frame, hydraulic
power supply and control system. Where steel pipes are used for hydraulic
connections, Instron will connect both ends of such runs with flexible hoses as
ordered by the customer.
Hydraulic System
Instron will provide the first fill of all necessary oils and lubricants, and will be
responsible for carrying out flushing of the hydraulic system where a complete
system has been supplied. If the customer’s own hydraulic oil installation is used,
Instron will not connect until the required standards of cleanliness have been
achieved by the customer at their expense. In those cases where the customer
desires to use an existing hydraulic supply or has incorporated steel pipe runs in a
package system but has not flushed the system to ISO Solid Contaminant Code
13/10 (U.S.A.), NAS Class 4, or Thermal Control Class 2 (U.K.). Instron will,
upon special request, carry out flushing and contamination checks on such
systems.

the system and for a calibration check and customer demonstration. Following the
initial demonstration of the equipment, further training can be given to the
customer by initially contacting the local Instron area office who will be happy to
advise.
Documentation
Instron will provide all necessary documentation. Further copies may be supplied
as itemised on the customer’s order.

General
If your hydraulic power supply is air-cooled, it may require an air blast cooler.
An air blast cooler circulates hot oil through an external radiator which has a large
fan attached. The fan forces cooling air through the vanes of the radiator, thus
cooling the oil quickly and efficiently.

Lifting and Handling
Outline
This chapter gives you information required for moving the load frame to your
desired location and unpacking it.
Unless specifically arranged otherwise, it is the customer’s responsibility to
arrange for off-loading, unpacking and transporting the equipment to the final site
at the customer’s premises. This includes insurance and safety responsibilities.
It is essential to transport the equipment by crane or fork-lift truck from the offloading site to an area for unpacking, as close as possible to the operating site.
While environmental conditions in the vicinity of the testing equipment are not
critical (refer to “Environmental Conditions” on page 3-20), attention should be
given to the siting of the equipment in locations where air-borne dust and dirt can
be held to a minimum. Floor loading is a major consideration, and a reasonably
level floor with a loading capacity in excess of three times the combined weight of
the load frame, control system and the operator is required. Ground floor locations
are preferred, as the loading capacity is usually sufficient and floor vibrations
during testing are minimised.
Warnings
.
Ensure that cranes or fork-lift trucks used to move the equipment have
adequate load capacity (1.5 × gross weight).
Ensure that slings used are serviceable and are of the correct length and
proof loading.
Ensure that the yellow safety collar is clamped under the crosshead
whenever the frame is moved.
Ensure that the crosshead clamp bolts have been tightened for transit to a
torque of 230 Nm (170 lb ft).

Raising the Frame
The 8800 Series Load Frames are packed and mounted horizontally on a pallet,
which should remain in position until the frame is at the operating site, where it
can then be removed with all other straps, hold-downs and loose packing material.
Caution
Do not use the column eye-bolts to raise the frame. They are to be used for
vertical lifting of the frame only.
Two Column Frames
In order to raise the frame to a vertical position, refer to Figure 4-1 and use the
following procedure.
a. Ensure that the crosshead is in the lowest position and that the metal support for the columns is fitted.
b. Fit a fibre sling around the top of the columns, below the metal support as
shown in Figure 4-1. Ensure that adequate packing material is used to
protect the columns.
c. Ensure that the crane or hoist is correctly positioned, and that the pivoting
edges of the frame feet are chocked to prevent movement during lifting.
d. Raise the frame to the vertical position.

Air Cushion Isolators
M21-28800-70
Air Cushion Isolators
The optional air cushion isolators must not be inflated without the weight of the
load frame upon them. They are therefore supplied fitted to the load frame, but
deflated for shipment.
When the frame is finally positioned at the testing site, they should be sequentially
pressurised to an air pressure which must not exceed 6 bar (90 psi). The overall
mount height between the frame foot and the floor should be 89 ± 6 mm (3.5 ±
0.25 in).
Caution
Deflate the air cushion isolators before moving the load frame.
If the load frame is subsequently moved, the air cushion isolators must first be
deflated. They must be re-inflated after the move is complete.

If a hydraulic power supply is not ordered from Instron, a hydraulic oil supply of
207 bar (3000 psi) will be necessary. Instron can advise on flow rates required.
The oil temperature must not exceed 50 °C (122 °F), and the recommended
filtration requirements are to ISO Contaminant Code 13/10 (U.S.) regulations,
NAS Class 4, or Thermal Control Class 2 (U.K.).
When the hydraulic power supply is to be situated at a distance greater than 6 m
(20 ft) from the load frame, steel pipe runs should be provided. Table 5-6 details

Hydraulic Power Supplies
the minimum bore of the steel pipe, and the maximum length of the pipe run
including the connecting hoses at either end. This is to ensure that the drain fluid
back-pressure remains within limits.
Please contact your Instron Sales Office for details of extended run Pressure and
Return line dimensions. These vary depending upon frame and hydraulic power
supply configurations.

Water Pressure
Caution
Do not use solenoid-operated water shut-off valves on the outlet side of the
heat exchanges. They cause water hammer effects which may cause
internal fractures of the hydraulic power supply, leading to water
contamination of the oil.
The recommended water pressure is 2 bar (29 psi) to 7 bar (100 psi).
Water Quality
Essential
Services
The efficiency of cooling of the hydraulic power supply oil system is highly
dependent upon the quality of the cooling water supply. An analysis of the supply
should be obtained from the local water supply authorities, particularly with
regard to pH levels and the level of suspended solids. As a minimum standard, the
pH level should be within 5.0 to 8.5, and filtration should be provided to screen
suspended particles of 0.8 mm or above.

It is recommended that the hydraulic power supply is situated remotely from the
actual operating location to minimise the nuisance from noise. If sound proofing
is used, then it is essential that adequate ventilation is provided to keep the motor
and power supply operating temperatures at the correct levels (refer to
“Ventilation” on page 5-10). A minimum distance of 600 mm (24 in) of free floor
space is required all around the hydraulic power supply to allow for installation
and maintenance.
