1.1 These test methods cover the apparatus and procedures for detecting pinholes and holidays in coatings used to protect pipelines. 1.2 Method A is designed to detect pinholes and holidays in thin-film coatings from 0.025?mm to 0.254 mm (1?mils to 10?mils) in thickness using ordinary tap...
1.1 This test method specifies a method for the determination of tap density (packed density) of metal powders and compounds, that is, the density of a powder that has been tapped, to settle contents, in a container under specified conditions. 1.2 Units-With the exception of the...

1.1 This specification provides requirements for materials, finish and marking, care and handling, and the acceptable dimensions and tolerances for metallic bone screws that are implanted into bone. The dimensions and tolerances in this specification are applicable only to metallic bone screws...
1.1 This practice covers a general procedure for using the Impulse Excitation Method (IEM) to facilitate natural frequency measurement and detection of defects and material variations in metallic and non-metallic parts. This test method is also known as Impulse Excitation Technique (IET), Acoustic...
1.1 This practice covers procedures for surveying concrete bridge decks by sounding to determine delamination in the concrete. It is not intended that the procedures described herein are to be used on bridge decks that have been overlaid with asphalt mixtures. The procedures may be used on bridge...
1.1 This test method covers a test that can be used to compare the cavitation erosion resistance of solid materials. A submerged cavitating jet, issuing from a nozzle, impinges on a test specimen placed in its path so that cavities collapse on it, thereby causing erosion. The test is carried out...
1.1 This test method covers the determination of the mechanically tapped density of powdered and fine mesh activated carbon. For the purpose of this test method, "powdered carbon" is defined as having a mean particle diameter less than 45?μm, and "fine mesh carbon" is defined as having a...
1.1 This test method covers the laboratory measurement of impact sound transmission of floor-ceiling assemblies using a standardized tapping machine. It is assumed that the test specimen constitutes the primary sound transmission path into a receiving room located directly below and that a...
1.1 This test method evaluates the resistance to freezing and thawing of solid interlocking concrete paving units conforming to the dimensional requirements of Specification C936/C936M. Units are tested in a test solution that is either tap water or 3?% saline solution, depending on the...
1.1 This test method specifies a method for the determination of tap density (packed density) of metal powders and compounds, that is, the density of a powder that has been tapped, to settle contents, in a container under specified conditions. 1.2 Units-With the exception of the...
1.1 These test methods cover the apparatus and procedure for detecting holidays in pipeline type coatings. 1.2 Method A is designed to detect holidays such as pinholes and voids in thin-film coatings from 0.025 to 0.254 mm (1 to 10 mils) in thickness using ordinary tap water and an applied...
This specification covers steel self-piercing tapping screws for use in fastening gypsum panel products and metal plaster bases to cold-formed steel studs and wood members and for fastening gypsum panel products to gypsum board. Steel screws covered by this specification are of four types of...
