1.4 General Chain Dimensions for Interchangeability

The dimensions given in lables 1 and 2 provide guidance that will ensure interchangeability and compatibility with standard design devises. It is recommended that these dimensions be considered foractual minimum and masintum limits. Manufacturers are

responsible for ensuring that their chains properly connect to the corresponding standard devises.

NOtE: Chaim. from dilferent manufacturers must neer be placed tu%ct*wr within the ,.anw applicatiws.

1.5 Minimum Ultimate Tensile Strength (MUTS)

Minimum ultimate tensile strength (MUTS). 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

WARNING The MUTh Is sot a “workim load.” The SIUTh greatly ecerds the m.aimum force that may be safely applied to the chain.

(a) Test Procedurr. A tensile force is slowly applied, in a uniaxial direction, to the ends of the chain sample.

(I’) The tensile test Is a destructive test. Even though the chain may not visibly fail when subjected to the MUTS, it will have

been damaged and wiLl be unfit for senice.

1.6 Tolerance for Chain Length

New chains may have a tolerance of ±0.031 in/ft (2.5S mm/rn) when measured under standard measuring load as outlined in para. 1.7.

1.7 Measuring Load

This is the load under which a chain is to be measured for length. II is equal to 1% of the MITTS. Length measurenwnts are to be

taken over a length of at least 12 in. (300 mm).

1.8 Preload

All chains shall be preloaded by applying a tensile force equivalent to at least 30% of the MUTS given in Table 3.
