Size px x x x x A tensile test is one of the simplest ways of testing a rope’s performance and quality. 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.

ASTM D – 93 Standard Test Methods for Testing Fiber Ropes (Withdrawn )

Criminal penalties may apply for noncompliance. Maribel Bonite Peneyra Category: Ropes are also used for sports such as mountain climbing.

There are several elongation calculations which can be found in the official publication: Additional precautions for these test methods are given in Section 5. Ultimate Tensile Strength UTS can also be transcribed if the max force is larger than the breaking force.

A number in parentheses indicates the year oflast reapproval. 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. 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.

ASTM D specifies a method for testing fiber axtm ropes. The values provided in parentheses are provided for information purposes only. These types of materials are used in the transportation industry in order to secure cargo.

Ropes are really just a series of individual fibers which are wound or braided to create larger strands and eventually, a rope or cord. Apply the pFescribed numbet of tensioning cycles continuously.

The wrap drum spreads the tensile stress over a wider area which helps with d42668 consistency and better simulates actual working conditions. Elongation is also v4268 and the modulus of elasticity can also be derived from this data as well. It can be expected that strength loss will occur dependi,ng llgation. Wrap grips are the best solution for ropes tensile testing because they reduce the propensity for the cord to slip during the pull.

It is anticipated ‘that the intedaborat. The cross-sectional area is the most important factor. Last previous edition D – If the rope is made of nylon or a similar type of material, it will probably need to be wrapped several times. Standard samples for ropes can vary between different aztm.

Thank you for interesting in our services. Breaking force is the force at which the rope breaks. The amount of times the cord must be wrapped depends on the coefficient of friction of the rope. We need your help to maintenance this website.
