Ropes are also used for sports such as mountain climbing. These types of materials are used in the transportation industry in order to secure cargo. The values provided in parentheses are provided for information purposes only. Apply the pFescribed numbet of tensioning cycles continuously.

A tensile test is one of the simplest ways of testing a rope’s performance and quality. The wrap drum spreads the tensile stress over a wider area which helps with procedural consistency and better simulates actual working conditions. We need your help to maintenance this website. The cross-sectional area is the most important factor. Breaking force is the force v4268 which the rope breaks. We are a non-profit group that run this website to share documents.
D – 93 Standard Test Methods for Testing Fiber Ropes 1 This standard is issued under d4286 fixed designation D ; the number immediately following the designation indicates the year of original adoption or, sstm the case of revision, the year oflast revision.

ASTM D – Rope Tensile Strength
Please help us to share our service with your friends. 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 or cord.
Size px x x x d268 Last previous edition D – It is anticipated ‘that the intedaborat. Standard samples for ropes can vary between different manufacturers. If the rope is made of nylon or a similar type of material, it will probably need to be wrapped several times.
Ultimate Tensile Strength UTS can also be transcribed if the max force is larger than the breaking force. Wrap grips are the best solution for ropes tensile testing because they reduce the propensity for the cord to slip during the pull.
Elongation is also important and the modulus of elasticity can also be derived from this data as well. Please fill this form, we will try to respond 4d268 soon as possible.
Additional precautions for these test methods are given in Section 5. Originally published as D – The amount of times the cord must be wrapped depends on the coefficient of friction of the rope.
Precision and Bias 3S. Criminal penalties may apply for noncompliance. There are several elongation calculations which can be found in the official publication: 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.
ASTM D specifies a method for testing fiber based ropes. Thank wstm for interesting in our services. 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.
