ASTM D – 93 Standard Test Methods for Testing Fiber Ropes (Withdrawn )

D42688 number in parentheses indicates the year oflast reapproval. D – 93 Standard Test Methods for Testing Fiber Ropes 1 This standard is issued under the fixed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year oflast revision.

Please help us to share our service with your friends. ASTM D specifies a method for testing fiber based ropes.

Last previous edition D – Ropes are also used for sports such as mountain climbing. Standard samples for ropes can vary between different manufacturers. A tensile test is one of the simplest ways of testing a rope’s performance and quality.

Thank you for interesting in our services. We are a non-profit group that run this website to share documents.

Wrap grips are the best solution for ropes tensile testing because they reduce the propensity for the c4268 to slip during the pull. We need your help to maintenance this website.

The wrap drum spreads the tensile stress over a wider area which helps with procedural consistency and better simulates actual working conditions. The cross-sectional area is the most important factor. It is anticipated ‘that the intedaborat. It can be expected that strength loss will occur dependi,ng llgation.

If the rope is made of nylon or a similar type of material, it will probably need to be wrapped several times. Maribel Bonite Peneyra Category: Elongation is also important and the modulus of elasticity can also be derived from this data as well. Ropes from different stages of the winding process are usually taken and tested so as to reduce the amount of potential scrap material and ensure the proper quality. These types of materials are used in the transportation industry in order to secure cargo.

Precision and Bias 3S. Additional precautions for these test methods are given in Section 5. There are several elongation calculations which can be found in the official publication: Breaking force is the force at which the rope breaks.

ASTM D – Rope Tensile Strength

Ultimate R4268 Strength UTS can also be transcribed if the max force is larger than the breaking force. We need your help! Ropes are really just a series of individual fibers which are wound or braided to create larger strands and eventually, a rope or cord. The values provided in parentheses are provided for information purposes only. The amount of times the cord must be wrapped depends on the coefficient of friction of the rope. 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.
