1.1 This test method covers the determination of the flexibility of a hot-melt adhesive in sheet form under specific test conditions. This is a working test. Its results are useful for comparing adhesives, not for absolute characterization of adhesives.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
这一试验是将一挠性材料和一刚性材料用导电胶制成胶接试样,然后将胶接试样以规定的速率从胶接的开口处剥开,两块被粘物沿着被粘面长度的方向逐渐分离。 按照标准要求制备试样:刚性被粘试片宽为 25.0 mm±0.5 mm,长为 200mm以上的长条。挠性被粘材料能弯曲180°而无严重的不可回复的变形。除非另有规定,挠性被粘试片的长度不小于 350mm。...
