Inspection item

Lead shot bag impacting characteristic

Standard requirement

II-1: 45+0.1kg lead shot bag, impact height is 1200mm, and samples do not destroy.  If samples destroyed, broken part should not be existed rupture or hole, which can let diameter 75mm ball freely pass.

II-2: 45+0.1kg lead shot bag, impact height is 750mm, and samples do not destroy.  If samples destroyed, broken part should not be existed rupture or hole, which can let diameter 75mm ball freely pass.

II-3: 45+0.1kg lead shot bag, impact height is 300~1200mm,

a). In broken, it allows to appear crack and smash things, but it does not allow to exist rupture or hole, which can let diameter 75mm ball freely pass.

b). After 1200mm impacted, samples is not always in testing frame, but it should be keep in integrity.
