GB/T 3250-2017Shearing and riveting test method of wires and rods for the aluminum and aluminum-alloy rivets (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 3250-2007 "Aluminum and aluminum alloy rivets and rivets shear test methods and rivets riveting test method." This standard compared with GB/T 3250-2007, in addition to editorial changes outside the main technical changes are as follows.

--- Modify the scope, and added bar products (see Chapter 1, 2007 edition of Chapter 1);

--- Increasing the normative references GB/T 16825.1-2008 "static uniaxial testing machine test Part 1: Rally and (Or) pressure testing machine testing system and calibration "and JJG351" industrial metal thermocouple test requirements " (See Chapter 2);

--- Modify the "Method Summary" and change "Method Summary" to "Method Summary" (see 3, 3.1 and 3.2, 2007 and 3, 3.1 and 3.2);

--- Increased high-temperature heating equipment and requirements (see 4.1.3);

--- Increasing the sample sampling site (see 4.2.1);

--- Increasing the shear specimen size specifications, diameter deviation and surface roughness requirements (see 4.2.2.2);

--- Increasing the original cross-sectional area of the sample formula (see 4.3.1);

--- Modify the shear test fixture aperture and radial clearance requirements of the sample (see 4.3.2, 2007 version 6.1.2);

--- Increased shear test high temperature test procedures (see 4.3.4,4.3.5);

--- Modify the shear test displacement speed (see 4.3.5, 2007 edition of 6.1.4);

--- Modify the requirements of riveting test tools (see 5.1, 2007 version 5.2);

--- Modify the evaluation of riveting test results (see 5.4, 2007 version 7.2);

--- Increasing the requirements of high temperature shear mold (see Appendix A);

--- Added double shear test fixture required appendix (see Appendix B).

This standard replaces the standards previously issued as.

--- GB/T 3250-1982, GB/T 3250-2007;

--- GB/T 3252-1982.
