Status: historical
Page Count: 4
ICS Code (Fasteners in general): 21.060.01
scope:

1.1 This specification covers the requirements for compressible-washer-type direct tension indicators capable of indicating the achievement of a specified minimum bolt tension in a structural bolt.

1.2 Two types of direct tension indicators in nominal diameter sizes 1/2 through 1 1/2 in. are covered:

1.2.1 Type 325-direct tension indicators for use with Specification A 325 bolts, and

1.2.2 Type 490-direct tension indicators for use with Specification A 490 bolts.

1.3 Direct tension indicators are intended for installation under either a bolt head or a hardened washer. (See Research Council on Structural Connections: Specification for Structural Joints Using ASTM A 325 or A 490 Bolts.)

1.4 The following precautionary statement pertains only to the test method portions, Section and of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
