Diamond ISO/British Standard carbon steel chain is manufactured to ISO standards (IS 606, BS228, DIN 8187) for dimensions, interoperability, and sprocket fit. Connecting links are spring clip type for sizes up to DMD-16B, and cotter type for sizes DMD-20B and up. Diamond Chain Company uses average tensile strength as it is a more appropriate value for strength and load calculations. Working load should not exceed
1/6th tensile strength under typical conditions when using a press fit connecting link or 1/9th tensile strength when using a slip fit connecting link or offset link.
