Variations in sleeve length and wristdimensions are acceptable when required to meet special phy

35、sical requirements.10.2.1 The taper of sleeves should be uniform as this is significant because of the advent of dry-form electrical testing.11. Workmanship and Finish11.1 Sleeves shall be free on both inner and outer surfaces of harmful physical irregularities that can be detected by thoroughtest a

36、nd inspection.11.1.1 Harmful physical irregularities may be defined as any feature that disrupts the uniform, smooth surface contour andrepresents a potential hazard to the user, such as pinholes, cracks, blisters, cuts, conductive embedded foreign matter, creases, pinchmarks, voids (entrapped air),

37、 prominent ripples, and prominent mold marks.11.2 Nonharmful physical irregularities may be defined as surface irregularities present on the inner and outer surfaces of therubber sleeve due to imperfections on forms or molds and inherent difficulties in the manufacturing process. These irregularitie

38、smay appear as mold marks that look like cuts even though they are actually a raised ridge of rubber, indentations, protuberances,embedded foreign material, or color splashes that are acceptable provided that:11.2.1 The indentations, protuberance or mold marks tend to blend into a smooth slope upon
