45、ble 3 B-1, and Table 4 B-2.7.3 Tubular bar dimensions shall be supplied in the unfin-ished condition, unless otherwise specified at time of order,sufficient to finish to the nominal dimension ordered.7.4 The maximum allowable camber and/or bow shall bewithin the limits referenced in Table 2 A-1, Tab
46、le 3 B-1, andTable 4 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 published by the shapes manufacturer. They shall
47、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 blisters, wrinkles,cracks, gouges and defects that re
48、strict 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 diameter as defined in 8.3.1.8.3.1 The criteria f
