welded-sieel-ivpe mill chums: a series of identical welded offset links having barrels to contact the sprocket teeth, and pins which articulate in the barrels of the links. Pins are fixed in the sidehar pitch holes by either press fits andlor mechanical locks, such as Oats, to prevent rotation of the pins in the sidebar pitch holes.
2 GENERAL CHAIN PROPORTIONS AND DESIGNATIONS
2.1 Minimum Ultimate Tensile Strength
The minimum ultimate tensile siren gui M . U .LS.) for chain covered by this Standard, is the minimum force at which an unused, undamaged. chain could fail when subjected to a single tensile loading test.
(a) WARNING: The mininum ultimate tensile
(b) Test procedure.A tensile force is slowly applied,in uniaxial direction，to the ends of the chain sample.
(c) The tensile test is a destructive test. Even thoughthe chain may not visibly fail when subjected to theminimum ultimate tensile force, it will have been dam-aged and will be unfit for service.
2.2 Measuring Load
Measuring load should be 5 times the weight of 10ft of chain，rounded to the nearest 100 lbs.
2.3 Dimensions for Chain Links
To assure interchangeability of links as producedby different makers of chain,standard maximum andminimum dimensions are adopted. They are not actualdimensions used in manufacturing, but limiting dimen-sions，maximum or minimum，required to assure thedesired interchangeability. However, due to minor varia-tions in barrel configurations,coupling chains of differ-ent manufacture should be held to a minimum.
