Scope

This European standard specifies the test method which allows to determine with a single test the torque/clamp force properties and/or the prevailing torque properties (performance properties) for prevailing torque type steel nuts when tested at an ambienttemperature range of + 10 °C to + 35 °C.It applies to prevailing torque all metal type nuts and prevailing torque non-metallic insert type nuts- with triangular ISO thread according to ISO 68;- with diameter/pitch combination according to ISO 261 and ISO 262;- with thread tolerance 6H according to ISO 965-2, except for the prevailing torque feature;- with coarse pitch thread M3 to M39 and mechanical proper
