AbstractThese test methods establishes the standard procedures for conducting tests to determine the mechanical properties of externally and internally threaded fasteners, washers and direct tension indicators, and rivets. For externally threaded fasteners, the mechanical tests describe the procedures for determining the following properties: product hardness; proof load by length measurement (Method 1), yield strength (Method 2), yield strength of austenitic stainless steel and nonferrous materials (Method 2A), and uniform hardness (Method 3); axial tension of full size products such as fasteners and studs; wedge tension of full size products such as fasteners and studs; tension of machined test specimens including yield point (by drop of the beam or halt of the pointer, autographic diagram, and total extension under load methods), yield strength (by offset, and extension under load methods), tensile strength, elongation, and reduction of area; and total extension at fracture. As for internally threaded fasteners including nonheat- and heat-treated nuts, tests are provided for the determination of product hardness, proof load, and cone proof load. Test for determining the surface and core hardnesses are, conversely, described for direct tension indicators, and through-hardened, carburized, stainless steel, and nonferrous washers. And finally, product hardness testing is described for rivets. The test method for determining embrittlement of metallic coated externally threaded fasteners is detailed as well.1.1 These test methods cover establishment of procedures for conducting tests to determine the mechanical properties of externally and internally threaded fasteners, washers, direct tension indicators, and rivets.1.2 Property requirements and the applicable tests for their determination are specified in individual product standards. In those instances where the testing requirements are unique or at variance with these standard procedures, the product standard shall specify the controlling testing requirements. In the absence of any specified test requirement(s), these test methods shall apply.1.3 These test methods describe mechanical tests for determining the following properties:  SectionFor Externally Threaded Fasteners: 3 Product Hardness 3.1 Proof Load 3.2.1  Method 1, Length Measurement 3.2.3  Method 2, Yield Strength 3.2.4  Method 3, Uniform Hardness 3.2.5 Axial Tension Testing of Full-Size Product 3.4 Wedge Tension Testing of Full-Size Product 3.5 Tension Testing of Machined Test Specimens 3.6 Total Extension at Fracture Test Single Sheer Test 3.73.8For Internally Threaded Fasteners: 4 Product Hardness 4.1 Proof Load Test 4.2 Cone Proof Load Test 4.3For Washers and Direct Tension Indicators: 5 Product Hardness-General Requirements 5.1 Through Hardened Washers 5.2 Carburized Washers 5.3 Stainless Steel and Nonferrous Washers 5.4 Direct Tension Indicators 5.5 Compression Load 5.6For Rivets: 6 Product Hardness 6.1Test for Embrittlement of Metallic-Coated Externally Threaded   Fasteners 7Test Method for Determining Decarburization and Carburization 81.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.NOTE 1: The values are stated in inch-pound for inch fasteners and SI metric units for metric fasteners.1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
