Standard Test Method for Measurement of Cut Resistance to Chainsaw of Foot Protective Devices

Importancia y uso:

5.1 The purpose of this test method is to provide a measurable criterion of performance defining the level of cut resistance to the cutting action of a saw chain provided by foot protective devices.

5.2 The protection which can be demonstrated by the foot protective devices tested in accordance with this test method is achieved by: (1) the material resisting cutting when put in contact with the moving saw chain; (2) a part of the material being drawn into the saw chain and drive mechanism to block the saw chain movement; (3) the materials resisting cutting and absorbing rotational energy so that saw chain speed can be slowed down sufficiently to stop the movement of the saw chain; or (4) any combination of these.

5.3 In case of a dispute arising from differences in reported test results, when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should perform comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens from the same lot of components to be evaluated. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. If a bias is found, either its cause must be determined and corrected, or the purchaser and the supplier must agree to interpret future test results in light of the known bias.
