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.

The amount of times the cord must be wrapped depends on the coefficient of friction of the rope. A number in parentheses indicates the year oflast reapproval. Ropes are really just a series of individual fibers which are wound or braided to create larger strands and eventually, a rope asym cord. These types of materials are used in the transportation industry in order to secure cargo.

Last previous edition D – We need your help to maintenance this website. We are a non-profit group that run this website to share documents. Ropes ast also used for sports such as mountain climbing. Originally published as D – If the rope is made of nylon or a similar type of material, it will probably need to be wrapped several times.

There are several elongation d428 which can be found in the official publication: Apply the pFescribed numbet of tensioning cycles continuously. Elongation is also important and the modulus of elasticity can also be derived from this data as well.

Breaking force is the force at which the rope breaks. Please fill this form, we will try to respond as soon as possible.

It can be expected that strength loss will occur dependi,ng llgation. 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.

Sstm wrap drum spreads the tensile stress over a wider area which helps with procedural consistency and better simulates actual working conditions. A tensile test is one of the simplest ways of testing a rope’s performance and quality. We need your help!

ASTM D – Rope Tensile Strength

Criminal penalties may apply for noncompliance. Standard samples for ropes can vary between different manufacturers. Wrap grips are the best solution for ropes tensile testing because they reduce the propensity for the cord to slip during the pull.

ASTM D specifies a method for testing fiber based ropes. 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.
