and/or GCC Clause 2.1(a)(ii).
STATEMENT OF
COMPLIANCE
SPECIFICATION
S C O P E : This specification establishes the
physical
characteristics
and
performance
requirements of steel poles for use on Eastern
Samar Electric Cooperatives, Inc. electric
distribution system. Poles furnished to NEA
specifications shall conform in all respects to the
performance of this standard. The text, figures and
references of other standards supplement each
other and shall be considered part of this standard.
The poles are to be of the embedded type and not
to require a special foundation.
MATERIAL: Steel poles shall be fabricated from
structural quality hot rolled steel which conforms to
ASTM A570-79, 'Standard Specification for HotRolled Carbon Steel Sheet and Strip, Structural
Quality.'
FINISHING: The pole shall be cleaned of scale,
rust, oil, paint and other surface contaminants and
then rinsed in an alkaline cleaning bath. The steel
78
BIDDER’S BID
/ FORM OF
EVIDENCE
shall then be bathed in a diluted acid (sulfuric or
hydrochloric) bath for at least five minutes. Just
prior to galvanizing, the acid cleaned steel shalt be
immersed in a flux solution of 30% zinc ammonium
chloride with wetting agents and maintained at 65
deg. C until galvanizing is completed. Steel poles
shall be hot dip galvanized in accordance with
ANSVASTM A153-82, Standard Specification for
Zinc Coating (Hot Dip) on Iron and Steel Hardware.
This standard requires a minimum zinc coating of
610 grams / sq. m. The coating shall be
continuous, smooth, reasonably uniform in
thickness and free of blemishes and other
imperfections which are inconsistent with
commercial practice. Galvanized articles shall be
free from coated areas, blisters, flux deposits, acid
and black spots, and dross inclusions. Lumps,
projections, globules, or heavy deposits of zinc
which will interfere with the intended use of the
material will not be permitted. All holes shall be
clean and reasonably free from excess zinc.
DIMENSION:
The poles are specified in
accordance with the ANSI Standard for
classification of wood poles; that is by length
andstrength class. The first number is the overall
length in feet and the second numberis the
designation of the strength class. A 35 foot pole
with a strength classification of 5 is abbreviated
35/5.The diameter of the pole at ground line shall
be similar to an equivalent wood pole of that height
and class to assure that the earth surrounding the
pole will provide the necessary resistance to
develop the strength of the pole.
S T R E N G T H : The strength of the pole is
specified as force acting at 90 degrees to the center
line of the pole at a point two feet from the top of the
pole. The amount of force in pounds that each
classification must be able to withstand without
damage is shown on the table below;

STATEMENT OF COMPLIANCE
SPECIFICATIONS
MARKINGS: Each steel pole shall be identified by
the supplier by stamping into the pole, prior to
coating, with letters not less than 1/2" high squarely
on the face of the pole at ten (10) feet from the butt
of the pole. The following information shall be
stamped into the pole:
Supplier's name
Month and year of manufacture
Length of pole
Class of pole
Type of coating
Pole production or serial number
The marks shall be legible after application of
the protective coating.
INSPECTION AND TESTING:
The manufacturer shall conduct factory tests to
verify that the poles comply with the requirements
of this standard. NEA reserves the right to witness
ANY OR ALL factory tests and the Supplier shall
notify NEA fifteen (15) days before each test is to be
conducted. The Supplier is required to furnish NEA
a copy of all test reports. NEA expects to
commission an internationally recognized third
party, independent inspection and/or testing agency
for independent inspection and/or testing at the
factory, prior to shipping or after receipt of the poles
in the Philippines. The galvanizing shall be tested in
accordance with ASTM Standard A 123-89. Any
pole that fails an inspection is automatically rejected
and additional poles from that lot must be tested in
accordance with the following testing schedule:
TESTING SCHEDULE:
One pole out of
every lot of 25 poles shall be tested to 50 percent of
its rated strength and a record kept of the deflection
after a two (2) minute hold at each multiple of 10
percent. This is a non-destructive test unless it
shows some weakness indicating the pole could not
meet the strength requirements and then it is to be
80
carried to destruction.
One pole out of every lot of 100 poles shall be
tested to destruction. If it fails at less than rated
strength, then four additional poles from the same
lot shall be tested to rated load. If they all pass, the
lot is considered to have passed that test. If two or
more of the additional test poles fail, the entire lot
will be rejected. If only one of them fails, ten more
from the same lot may be tested to rated load. If
there are no failures, the remaining poles of that lot
are considered to have passed that test, however, if
there are any failures in these ten, and then the lot
is automatically rejected.
PROCEDURE
Proof Load Test:
Initially set the dynamometer to a load of 40% of
the minimum breaking load. Apply load steadily
until it reaches 40%. Hold for two (2) minutes.
Note for the development of weld cracks or
splitting. If any appear at the 40 % load, the pole is
considered to have FAILED the test and the batch
represented shall be rejected.
Break Load Test: Initially set the dynamometer to a
load of 40% of the minimum breaking load. Apply
load steadily until it reaches 40%. Hold for one (1)
minute. Note for the development of weld splits or
cracks. If cracks appear at 40% load, the pole is
considered to have failed the test. The batch
represented shall be rejected.
If no cracks or splits appear after the application of
40% load, set the dynamometer to a load of 50% of
the minimum breaking load. Apply load steadily until
it reaches 50%. Hold for one (1) minute. Note for the
development of cracks or splits. If found the pole is
considered to have failed the test. Release load to zero.
Upon removal of the load, immediately increase
the load gradually to 70% of the minimum
breaking load and hold for two (2) minutes. Note
for the development of additional cracks or splits.
Again remove the load and sussessivety increase the
load by an amount equal to 10% of the minimum
81
breaking load up to 80% and thereafter increase by 5%
of the minimum breaking load until failure occur, hold
each load for two (2) minutes.
Measure load at the point of failure to the nearest 5
kilograms.
The pole is considered to have failed the break
load test if it yielded at less than the minimum
breaking load.
REPORT
For tests conducted at source, the test shall be
prepared by the manufacturer in coordination with
the witnessing inspection engineer or test engineer.
