5.1 The measurement of the strength of leather is often necessary in order to determine its suitability for its intended application. This test method is recommended for use on light, soft leathers, narrow strap, welt, lace and round belt leathers as well as others that cannot be accurately tested by Test Method D2209.

1.1 This test method covers the determination of the breaking strength of leather by the grab method. It is intended for use on light, soft leathers; boarded, sueded, or embossed leathers tested on a specimen in the form of a rectangle piece; narrow strap, welt, lace, and round belt leathers; or other leathers that cannot be accurately tested by Test Method D2209. This test method does not apply to wet blue.

1.2 The test method is not recommended for breaking loads over 500 lbf (2200 N) because of slippage of the specimen in the jaws.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
