Standard Test Method for Indentation Hardness of Rigid Plastics by Means of a Barcol Impressor
Abstract: 5.1 The Barcol Impressor is portable and therefore suitable for testing the hardness of fabricated parts and individual test specimens for production control purposes. 5.2 Before proceeding with this test method, reference ... -
Standard Test Method for Evaluation of Visual Color Difference With a Gray Scale
Abstract: 5.1 The total perceived color difference between two non-self-luminous specimens is compared as an equivalent lightness difference between two neutral gray specimens on a gray scale. A fundamental assumption is made that ... -
Standard Specification for Through-Thickness Tension Testing of Steel Plates for Special Applications
Abstract: This specification covers procedures and acceptance standards for the determination of reduction of area using steel plates as tension test specimen. The tension testing method shall provide a measure of the resistance of ... -
Standard Test Method for Tensile-Shear Strength of Adhesives in the Subzero Temperature Range from −267.8 to −55°C (−450 to −67°F)
Abstract: 4.1 This test method may be used as an accelerated screening test for assessing the strength properties of adhesives and adhesive joints at subzero temperatures. This test method may also be used to determine the effects ... -
Standard Practice for Fusion of Poly(Vinyl Chloride) (PVC) Compounds Using a Torque Rheometer
Abstract: 5.1 When PVC compounds are mixed under appropriate conditions of heat and shear, a fused mass is produced. This mass has certain melt characteristics which can be defined with a torque rheometer operated under fixed ... -
Standard Tolerances for Manufactured Organic-Base Filament Single Yarns
Abstract: 4.1 These tolerances may be used as a guide in purchaser/supplier disputes, or to assist in assigning nominal values for linear density and twist. The tolerances listed for each property represent the maximum variations ... -
Standard Practice for Classification of Soils for Engineering Purposes (Unified Soil Classification System)
Abstract: 5.1 This standard classifies soils from any geographic location into categories representing the results of prescribed laboratory tests to determine the particle-size characteristics, the liquid limit, and the plasticity ... -
Standard Test Method for Water-Soluble Salts in Pigments by Measuring the Specific Resistance of the Leachate of the Pigment
Abstract: 4.1 This test method provides a reliable means for the determination of the relative amounts of these salts when comparing different lots of the same pigment grade. Water-soluble salts also affect the water resistance and ... -
Standard Test Methods for Scrub Resistance of Wall Paints
Abstract: 4.1 Paints often become soiled, especially near doorways, windows, and in work and play areas. These test methods cover the determination of the relative resistance of different paints to erosion when repeatedly scrubbed ... -
Standard Practice for Determination of the Impact Resistance of Thermoplastic Pipe and Fittings by Means of a Tup (Falling Weight)
Abstract: 4.1 The impact resistance of thermoplastic pipe and fittings relates to suitability for service and to quality of processing. Impact resistance may also provide a relative measure of a material's resistance to breakage ... -
Standard Test Methods for Rubber Thread
Abstract: 3.1 For adequate service performance, rubber threads must be tested by appropriate test methods. This standard gives a number of test methods that are known to be important in rubber thread technology. -
Standard Test Method for Coking Value of Tar and Pitch (Modified Conradson)
Abstract: 5.1 This test method is useful for indicating the relative coke-forming propensities and for evaluating and characterizing tars and pitches. This test method can also be used as one element in establishing the uniformity ... -
Standard Specification for Precipitation-Strengthened Low-Carbon Nickel-Copper-Chromium-Molybdenum-Columbium (Niobium) Alloy Structural Steel Plates
Abstract: This specification covers precipitation-strengthened low carbon nickel copper-chromium-molybdenum-columbium alloy structural steel plates. Precipitation strengthening and precipitation heat treatment shall be performed on ... -
Standard Test Method for Carbon Black—Oil Absorption Number (OAN)
Abstract: 4.1 The oil absorption number of a carbon black is related to the processing and vulcanizate properties of rubber compounds containing the carbon black. -
Standard Test Method for Ash in Coal Tar and Pitch
Abstract: 5.1 This test method determines the amount of inorganic matter in the sample. -
Standard Practice for Underground Installation of Thermoplastic Pipe for Sewers and Other Gravity-Flow Applications
Abstract: 4.1 This practice is for use by designers and specifiers, installation contractors, regulatory agencies, owners, and inspection organizations who are involved in the construction of sewers and other gravity-flow applications ... -
Standard Test Method for Measuring Area of Leather Test Specimens
Abstract: 4.1 This test method is designed to measure the area of specimens before and after they are subjected to various tests that may effect surface area. Two test procedures wherein such measurements could be used are for the ... -
Standard Practice for Testing Water Resistance of Coatings in 100 % Relative Humidity
Abstract: 4.1 Water can cause the degradation of coatings, so knowledge of how a coating resists water is helpful for assessing how it will perform in actual service. Failure in tests at 100 % relative humidity may be caused by a ... -
Standard Test Method for Metal Corrosion by Halogenated Organic Solvents and Their Admixtures
Abstract: 4.1 These tests are to be used as a guide in selecting or eliminating certain solvents or grades of solvents used for cleaning or degreasing metal parts.
