Historical Standard: Standard Specification for Compressible-Washer-Type Direct Tension Indicators for Use With Structural Fasteners [Metric]

ASTM F959M

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 M16 through M36 are covered:

1.2.1 Type 8.8—Direct tension indicators for use with Specification A 325M bolts, and

1.2.2 Type 10.9—Direct tension indicators for use with Specification A 490M 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 methods portion, Section 12 and Appendix X1, 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.
