7、07.9 by279.4-mm)test specimens are cut from these samples so thattheir length is parallel to the cross direction.The specimens areidentified and checked for ink penetration using special testink,a draw-down rod instrument and special receptor paper onwhich a lined rectangular pattern is drawn.The sa
8、me check isrepeated with an acceptable control tissue and the test resultsfrom the specimens and the control are compared visually,using the rectangular area.5.Significance and Use5.1 This practice is to be used to provide a visual means ofdetermining the existence of pinholes by penetration of a dy
