It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The wrap drum spreads the tensile stress over a wider area which helps with procedural consistency and better simulates actual working conditions. ASTM D specifies a method for testing fiber based ropes. Ropes are also used for sports such as mountain climbing.

There are several elongation calculations which can be found in the official publication: These types of materials are used in the transportation industry in order to secure cargo. Ultimate Tensile Strength UTS can also be transcribed if the max force is larger than the f4268 force. Elongation is also important and the modulus of elasticity can also be derived from this data as well. Precision and Bias 3S.
