1.2.1 By agreement between the purchaser and the supplier, or as required by established safety standards, it will be decided if this test method will be used to determine one or both of the following: (1) chainspeed 50 (CS50), and (2) success/failure (jamming/chain stop or no cut in less than 1.5 seconds) at specified chain speed.

1.3 This test method may be used to determine levels of protection for areas of coverage as stipulated in established safety standards.

1.4 The values stated in SI units are to be regarded as standard.

Note 1 The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
