Scope
1.1
JDHZ 610 includes guidelines for design in selecting appropriate appearance class as well as
methodology to verify that the final product meets or succeeds the quality expectations of John Deere Crop
Harvesting equipment customers.
1.2
JDHZ 610 applies to the evaluation of purchased and manufactured parts at all levels of the Crop
Harvesting platform. Where further interpretation of the intent of the standard is required, the following
guidelines should always be used to clarify the appearance of product throughout the manufacturing
process, including before shipment to the customer.
Note 1
This standard has been developed in conjunction with units within Global Crop Harvesting Platform which
uses JDHZ 612, JDN 237, JDE 10050, JDE 10020, JDH 430, JDH 803, as well as referencing RWS 1330.01.

This standard can contain mandatory provisions, which are identified by the words “shall” or
“required”. Compliance with the mandatory provisions is required to claim conformance with this standard.
This standard can also contain guideline provisions, which are generally identified by the words “should” or
“recommended”. Compliance with the guideline provisions is not required, because they might not be
appropriate for all machines or all applications.

Applicability
2.1
This JDHZ 610 standard has been developed by and for Crop Harvesting Platform. Any other unit,
division, or platform may adopt usage of this standard. The requirements of this standard shall be met fully
for any unit, division, or platform specifying this standard.

Terms and Definitions
For the purpose of JDHZ 610 the following terms and definitions apply.
3.1
bleed-in
Applies to adhesives. Excess material outside the application boundaries toward the inside of cab. A visible
symptom of variations in the adhesive bead size. See ‘Snakeheads’ below.
3.2
bleed-out
Applies to adhesives. Excess material outside the application boundaries toward the outside of cab. A
visible symptom of variations in the adhesive bead size. See ‘Snakeheads’ below
3.3
blisters
Related to the RIM process, voids within the wall of the part. Blisters may only be visible prior to painting
if the plastic has no pigmentation, otherwise the blister may show up after paint as a result of the gases
inside the void expanding and causing a raised bump. If seen prior to paint the blister can be cut open on
the nonappearance side of the part preventing the bump.
3.4
blow hole
Small through hole, caused by trapped air gas.
3.5
bond draw / read through
Surface distortion as a result of an adhesive bond on the underside of an appearance surface.

3.6
bubbles
Occurrence of air or solvent vapors form as small bubbles or ruptures of the paint film.
3.7
boil out / kick out
Excess E-coat material trapped in a part that during the curing process is boiled out on to the surface of
the painted part. Kick out is caused by the presence of high or low pH on the surface of the substrate
which renders the E-coat material insoluble and deposits heavy/rough film.
3.8
bunching
Number of defects grouped or joined together. Bunching for this standard is defined as 5 defects in 50mm
x 50mm area. Next bunch no closer than 600mm.

3.9
burn-in sand

casting.
3.10
chipping
One or more layers of paint removed.
3.11
cold shot
Piece of plastic from last shot left in nozzle which solidifies between shots and is forced unto the part along
with melted plastic.
3.12
cold slug
The first material to enter an injection mold. Creates surface imperfections around gates and sprues.
3.13
corrodible area
Recessed or obstructed portion of the equipment that is typically difficult to obtain full paint coverage and
to visually inspect by normal processes.
3.14
corrosion
Gradual degradation or destruction of material by chemical and/or electrochemical reaction with the
environment, see JDS-G223.
3.15

on edges.
3.21
dry spray

commonly caused by over spray. The fine mist falls on an area, causing a lowering of gloss and surface
smoothness.
3.22
film/smear
Residue or overspread of caulk or adhesive material outside the application boundaries. Appearance of a
haze or discoloration.
over spray
Spray paint, which misses the intended part or area being painted. The fine mist falls on another part or
area, causing a lowering of gloss and surface smoothness. Over spray is a different color of paint, whereas
dry spray is same color.
3.23
dust
Foreign material in the paint film. Dust is small in nature, exhibiting a look of fine haze in the paint film at a
viewing distance of ≈1 meter.
3.24
ejector pin mark read through
Surface imperfection caused by the ejector pin on the underside of the part causing surface distortion on
the appearance side. Read through can be caused by a change in wall thickness or temperature variations
due to the ejector pin. Can be identified by the witness line on the underside of the part.
3.25
excess metal
Extra iron on the casting surface sometimes from normal operative practice (gates, risers) or abnormalities
in the process (stickers, scabs).
