1.1 This specification defines the minimum requirements for agencies engaged in any of the following: (a) Inspection of specified methods and materials used in construction, (b) Special Inspection, and (C) Testing of materials used in construction.

1.1 This document describes the appearance of a radio-graphic image where fundamental components of image qual-ity are changed, that is, variables such as whether an X-ray orgamma ray source was used, the characteristics of the radio-graphic film (gradient, granularity, and developing conditions)and intensifying screens, and specimen thickness (the geo-metrical configuration ofthe radiographic set-up and focal

1.1 This test method covers the determination of the nil-ductility transition (NDT) temperature of frritie steels, 5/5 in.(15.9 mm) and thicker. 1.2 This test method may be used whenever the inquiry,contract, order, or speeifceation states that the steels are subject to fracture toughness requirements as determined by the drop-weight test.

1.1 This practice covers a procedure for fabricating alumi-num aloy ultrasonic standard reference blocks that can be used for checking performance of ultrasonic testing equipment and for standardization and control of ultrasonic tests of aluminum aloy prodlucts using pulsed longitudinal waves introduced into test material either by the direct-conact method or by the immersion method

1.1 These test methods cover the determination of the Vickers hardness and Knoop hardness of metallic materials by the Vickers and Knoop indentation hardness principles. This standard provides the requirements for Vickers and Knoop hardness machines and the procedures for performing Vickers and Knoop hardness tests.

1.1 This fire-test–response standard for the comparative surface burning behavior of building materials is applicable to exposed surfaces such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The material, product, or assembly shall be capable

1.1 These test methods cover a number of recognized procedures for determining the nonmetallic inclusion content of wrought steel. Macroscopic methods include macroetch,fracture, step-down, and magnetic particle tests. Microscopic methods include five generally accepted systems of examina-tion. In these microscopic methods, inclusions are assigned to a category based on similarities in morphology, and not necessarily

1.1 These test methods describe notched-bar impact testing of metallic materials by the Charpy (simple-beam) test and the Izod (cantilever-beam) test. They give the requirements for:test specimens, test procedures, test reports, test machines (see Annex A1) verifying Charpy impact machines (see Annex A2),optional test specimen configurations (see Annex A3), desig-nation of test specimen orientation (see

1.1 These test methods cover procedure and equipment for the determination oftensile strength, yield strength, elongation,and reduction ofarea ofmetallic materials at elevated tempera-tures. 1.2 Determination of modulus of elasticity and proportional limit are not included.

1.1 These test methods cover the apparatus, specimens, and procedure for axial-force compression testing of metallic materials at room temperature (Note 1). For additional require-ments pertaining to cemented carbides, see Annex A1. N OTE 1—For compression tests at elevated temperatures, see Practice E209.
