Torque Testing Standards

This test method outlines the recommended procedure for performing the no-load rotational starting torque test on airframe rolling bearings. Bearings covered by this test method shall be antifriction ball bearings and spherical roller bearings.

5.1 This test method allows for the measurement of the torque retention properties of container/continuous thread closure systems of various designs, materials, and manufacture, and is suitable for package development and engineering evaluation. 5.2 Each test method can be used...

This standard specifies the prevailing torque test for automobile lock nut.Note 1) Note 1) It is called a prevailing torque type nut and classified into 2 types as follows. 1 A type, a portion of bearing surface is deformed for prevention of loosening. 2 A type, resin is...

This Aerospace Recommended Practice (ARP) is intended to establish recommended installation torque value limits and test criteria for machined flared and flareless hose and tube end fitting connections. Assembly of bite-type MS21922 flareless sleeves is not included in this ARP (see...

5.1 This test method can be used to predict the comparative lubricating properties of a metalworking fluid (MWF). 5.1.1 Fluids that produce lower torques or higher efficiencies are predicted to have better machining characteristics. 5.2 The method is applicable to all tap types,...

This standard provides a test method for determining the torque-tension relationship of a fastener finish as applied to a surrogate screw for the purpose of measuring the frictional characteristic of the fastener finish. The results obtained by this test shall be used as a...

This standard applies grease used to lubricate auto parts.. PURPOSE This standard aims at measuring the lubricating capability of grease at low temperature by measuring the torque applied to a bearing at low temperature when a bearing is fully greased.

This test method describes a laboratory technique to evaluate the relative performance of metal removal fluids using an instrumented tapping machine that measures and records torque. The method is applicable to all tap types, machining speeds, and alloys that can be fabricated into a...

This Standard specifies a test method for the determination of the opening and closing torque of thermoplastics valves.

This test method outlines the recommended procedure for performing the no-load rotational starting torque test on airframe rolling bearings. Bearings covered by this test method shall be antifriction ball bearings and spherical roller bearings.

Specifies test necessary to determine opening and closing torque of valves.

This test procedure is intended to provide a quality control method for checking torque-tension characteristics of non-prevailing torque-type threaded steel fasteners 1/4 through 1 in nominal diameters. Realistically torque-tension relationships for specific individual...

PURPOSE This Worldwide Standard provides a test method for determining the torque/clamping force performance of fastener finishes specified in WX 100 and used on ISO Metric threaded bolts, screws, studs, and nuts under standard conditions. Note: This standard is not intended for use...
