This document establishes workmanship standards for surface finishes of products produced by or supplied to xxx. It defines three classes (A, B, C) of surfaces based on how frequently they are viewed, and the corresponding inspection requirements. It provides definitions of common defects and the acceptance criteria for each class of surfaces, including limits for scratches, dents, sinks, die marks and other defects on plastic, sheet metal and painted surfaces. Strict standards are defined for Class A surfaces that are most visible to customers.

1. Workmanship Standard Template

2. WORKMANSHIP STANDARD
1.0 PURPOSE
The purpose of this “Workmanship Standard” is to establish the criteria for “Acceptable” and
“Unacceptable” (rejectable) surface finishes for xxx products, as well as defines inspection
requirements for suppliers and source/receiving inspections by xxx.
2.0 SCOPE
This Cosmetic Workmanship Standard applies to all products produced by or supplied to xxx.
3.0 PRECEDENCE
3.1 The order of precedence, in the case of conflict between documents , is:
• Purchase Order or Requirements
• *** Engineering Drawings/Prints
• *** Cosmetic Workmanship Standards, XYZ, Co
• Other pertinent/relevant documents

3. 4.0 SURFACE CLASSIFICATION
1. CLASS A
Any surface continually or frequently viewed by the customer (front panel, faceplate, etc.)
2. CLASS B
Any surface occasionally viewed by the customer (top or side panels of a chassis)
3. CLASS C
Any surface not visible to the customer, except when the unit is, moved (bottom, or inside
walls of the chassis)

4. Surface Class Viewing Distance Viewing Time
A 18 inches ( 45 cm) 10 seconds
B 24 inches ( 61 cm) 5 seconds
C 34 inches ( 86 cm) 3 seconds
5.0 INSPECTION REQUIREMENTS
1.Lighting Requirements:
The “source” light shall be at least 500 lux on the inspection work surface/workplace. Cool
fluorescent or day light fluorescent is preferred.
• Parts shall be inspected without magnification, at an angle within 0 to 45 of the
inspected surface.
• Inspection Time and Distance:

5. 6.0 DEFECT DEFINITIONS
BLEEDING – Color altering or overlapping.
BLOTCH – Spot of plating or liquid on the metal surface.
BURN – Discoloration caused by thermal overexposure.
CHIPPING/FLAKING – Paint can be removed with light rubbing. Lack of paint adhesion.
CORROSION – Oxidation (rust) on the base metal, underneath the painted or plated surface.
CRACK – Material is broken or shows signs of separation.
DENT – Deep pit. Can be seen or felt.
DIE MARK – Tooling mark visible under finished surface.
DIRT – Particles, covered by paint or on the paint surface.
DISCOLORATION – Any change from the original color.
FLASH/BURR – Excessive material along parting lines or edges.
GOUGE – Indentation (groove) that can be felt or seen.
HAZE – Cloudiness of an otherwise clear finish (lacquer, plating, etc.).

6. KNIT/PARTING LINE – Line, where two material flows meet. Sometimes appears as a crack.
LINT – Strands of fiber, embedded in or covered by paint.
MARK – Visible black or dark marking.
ORANGE PEEL – Paint is not properly adhering to the surface.
PAINT SHADE – A lighter or darker shading in an area when compared to the original finish.
PITS – Small craters on the surface.
PROTRUSION – Raised area on a surface (blister, ridge, etc.).
RUN – Line of excessive paint on the surface.
SCRATCH – Shallow line of damage on the surface. The scratch doesn’t penetrate the base material.
SINK – Depression on the surface of the material.
SMEARING – Presence of ink on non-specified areas.
SPECKS – Small particles.
SPLAY – Excessive moisture during molding, creating “splash marks” or “silver streaks”.
VOID – Missing or lack of paint, plating or silk screen.
WELD LINE – Indentation visible under painted or plated surface.
