34、r bow shall bewithin the limits referenced in Tables A-1, B-1, and B-2.8. Workmanship, Finish, and Appearance8.1 AppearanceThe resin material color is transparentwith water-white or light straw color. Natural resin is alsooffered with various amounts of blue tinting. The product colorshall be as pub
35、lished by the shapes manufacturer. They shall beuniform in color throughout the thickness. Specific colors andcolor matching only as agreed to by order.8.1.1 Physical properties, although unaffected by tinting,can be affected if coloring by other means.8.2 FinishAll products shall be free of blister
36、s, wrinkles,cracks, gouges and defects that restrict commercial use of theproduct. Special surface finish shall be supplied only whenspecified in the purchase order or contract.8.3 DefectsAll products shall be free of voids, dirt,foreign material and embedded particles exceeding 0.040 in.maximum dia
37、meter as defined in 8.3.1.8.3.1 The criteria for determining the internal cleanlinessshall be external visual inspection. A maximum number of twointernal defects per square foot of plate and one foot length ofrod and tubular bar are allowed. Clusters of defects less than0.040 in. diameter are to be
38、counted as a single defect.8.3.2 For compression molded products, four defects up to0.080 in. diameter per square foot of plate are allowed.9. Sampling9.1 Sampling shall be statistically adequate to satisfy therequirements of this specification as applicable (see ANSI Z1.4- 1993).9.2 For purposes of

Number of Tests10.1 Routine lot inspection shall consist of all the criteriaspecified in the applicable product tables.10.2 The
40、 criteria listed in these product tables and defini-tions are sufficient to establish conformity of the sheet, plate,rod or tubular bars to this specification. When the number oftest specimens is not stated in the test method, a singledetermination is sufficient. If more than single determinationsan
