ASME Standards

This Standurd covers ratings, dimensions, tolenances,marking and material requirements for forged fitings,s both socket-welding and threaded, as ilustrated in Tables 4 through 7 and Il through I4, inclusive.

link: a one-piece steel link consisting of end bar A,hook B, and two sidebars CC (see Fig. 2 of B29.6). measuring load: the load under which a dry or lightly lubricated chain should be measured for length.steel detachable link chain: a series of sccessively assem-bled steel links in which the end bars articulate inside the

weled-steel-1ype mill chains: 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 sidebar pitch holes by either press fits and/or mechanical locks, such as flats, to prevent rotation of the pins in the sidebar pitch

This Standard covers roller chains that are specifically designed to withstand occasional high shock loads or high starting loads that are encountered in certain con-struction equipment and other severe-duty applications. WARNING: Chains covered in this Standard shall not be used as the primary lifting member, or in the direct drive line of elevators, escalators, or

A leaf chain consists of a series of link plates alternately assembled with pins in such a way that the joint is free to articulate between adjoining pitches. Typical assemblies are depicted in Figs. 1 and 2.

ThisStandardappliestothedesign,construction,instal-lation, maintenance, inspection, and operation of conveyors and conveying systems in relation to hazards. The conveyors may be of the bulk material,package, or unit-handling types, where the installation is designed for permanent, temporary, or portable opera-tion.

This quality-focused Standard establishes in-process and final inspection requirements for fastener products as well as a receiving inspection plan for fastener pur-chasers. This Standard identifies four categories, recog-nizing that fastener users have widely varying requirements. The fourcategories covered are as follows: (a) Category 1 — a receiving inspection plan for purchasers (b) Categories 2 and
