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 Four types of direct tension indicators in nominal diameter sizes 1/2 through 11/2 in. are covered: 1.2.1 Type 325—direct tension indicators for use with Specification A325 Type 1 bolts or F or F1852 assemblies. 1.2.2 Type 325–3—direct tension indicators for use with Specification A325 Type 3 or F1852 Type 3 assemblies. 1.2.3 Type 490—direct tension indicators for use with Specification A490 Type 1 bolts or F2280 assemblies. 1.2.4 Type 490–3—direct tension indicators for use with Specification A490 Type 3 F2280 Type 3 assemblies. 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 A325 or A490 Bolts.) 1.4 This specification provides for furnishing Types 325–3 and 490–3 to a Chemical Composition Requirement or a Corrosion Resistance Index (CRI) at the suppliers option. 1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 The following
precautionary statement pertains only to the test method portions,
