(b) Test procedure. A tensile force is slowly applied. in uniaxial direction, to the ends of’ the chain sample.
(c) The tensile lest is a destructii’e lest. Even though the chain may not visibly fail when subjected to the minimum ultimate tensile fi)rce, it will have been damaged and will be unfit for service.
2.2 Measuring Load
Measuring load should be 5 times the weight of 10 ft of chain, rounded to the nearest 1(X) lbs.
2.3 Dimensions for Chain Links
To assure interchangeability of links as produced by different makers of chain, standard maximum and minimum dimensions are adopted. They are not actual dimensions used in manufacturing. hut limiting dimensions, maximum or minimum, required to assure the desired interchangeability. However, due to minor variations in barrel configurations, coupling chains of difl’erent manufacture should he held to a minimum.
