Becauseit may not be technically possible to adequately depict all changes accurately, ASTM recommends

14、that users consult prior editions as appropriate.

15、(CS50), nfor chain saw protection, the mean velocity chain speed at which cut through occurs.3.1.7.1 DiscussionThis value establishes the relationship between the probability of cutting through the chain saw leg protective clothing (or footprotective device) and the speed of the saw chain. For lower

16、 chain speeds, the probability of cut through approaches zero, whilefor higher chain speeds, the probability of cut through approaches one.3.1.8 chain stop, nfor chain saw cut resistance, the resulting action when a material clogs (jams) the drive sprocket or slowsthe speed sufficiently to prevent a
