Density Standards

4.1 This test method is often used to determine bulk density values that are necessary for use for many methods of selecting proportions for concrete mixtures. 4.2 The bulk density also may be used for determining mass/volume relationships for conversions in purchase agreements....

1.1 This test method covers the determination of the vibratory packing density of formed catalyst and catalyst carrier particles that will not break up significantly under test conditions. For the purpose of this test, catalyst particles are defined as extrudates, spheres or formed pellets...

1.1 This test method covers the determination of the vibratory packing density of formed catalyst and catalyst carriers. For the purpose of this test, catalyst particles are defined as extrudates, spheres, or formed pellets of 0.8-mm to 4.8-mm (1/32-in. to 3/16-in.) nominal diameter. 1.2 The...

1.1 This standard describes a method for measuring the density of powder metallurgy products that usually have surface-connected porosity. 1.2 The density of impermeable PM materials, those materials that do not gain mass when immersed in water, may be determined using Test Method...

This specification covers characteristics for chemistry, microstructure, density, hardness, size, shape, and appearance of zirconium oxide-based ceramic shot, suitable for peening surfaces of parts by impingement.

1.1 These test methods cover procedures for measuring size, dimensional measurement, bulk density, warpage, and squareness of rectangular dense refractory brick and rectangular insulating firebrick. More precise determination of bulk density of refractory brick can be made by Test...

00651a-000000-000000 1 Scope 1.1 These requirements cover smooth-wall straight length and coiled continuous length conduit with a circular cross section, including elbows. Included are Schedule 40, Schedule 80, EPEC-A, EPEC-9, EPEC-11, and EPEC-13.5 high density PE electrical conduit. 1.2...

1.1 This test method covers the procedure for determining percent devulcanization from crosslink density measurements of devulcanized rubber and control crumb rubber in the laboratory. Percent devulcanization is a quantitative determination. 1.2 The values stated in SI units are to be...

3.1 Apparent porosity, water absorption, apparent specific gravity, and bulk density are primary properties of refractory shapes. These properties are widely used in the evaluation and comparison of product quality and as part of the criteria for selection and use of refractory products in a...

This specification covers concentric-lay-stranded conductors made from uncoated hard-drawn round copper wires in combination with hard-drawn round copper-clad steel wires for general use as overhead electrical conductors. The conductors are classified under the following type designations: Type A,...

5.1 This practice allows for the recovery and enumeration of viable and culturable, non-tuberculosis, rapidly growing Mycobacteria (M. immunogenum, M. chelonae, M. absessus, M. fortuitum, and M. smegmatis) in the presence of high Gram-negative background populations in metalworking fluid field...

1.1 This fire-test-response standard describes a procedure for measuring the minimum concentration of oxygen, expressed as percent volume, that will just support flaming combustion in a flowing mixture of oxygen and nitrogen. 1.2 This test method provides three testing procedures. Procedure A...

5.1 Measurement of mycobacterial cell count densities is an important step in establishing a possible relationship between mycobacteria and occupational health-related allergic responses, for example, hypersensitivity pneumonitis (HP) in persons exposed to aerosols of metalworking fluids. It...

This test method covers determination of the density of freshly mixed concrete and gives formulas for calculating the unit weight, yield or relative yield, cement content, and air content of the concrete. Yield is defined as the volume of concrete produced from a mixture of known quantities...

1.1 These test methods cover the preparation and tensile testing of resin-impregnated and consolidated test specimens made from continuous filament carbon and graphite yarns, rovings, and tows to determine their tensile properties. 1.2 These test methods also cover the determination of the...

1.1 This specification covers Liquefied Natural Gas (LNG) density calculation models for use in the calculation or prediction of the densities of saturated LNG mixtures from 90K to 120K to within 0.1?% of true values given the pressure, temperature, and composition of the mixture. 1.2...

This specification covers reinforced plastic pipe and fitting system made from epoxy resin and glass-fiber reinforcement, together with adhesive for joint assembly, intended for services in aviation jet turbine fuel lines installed below ground. The fiberglass pipe shall be round and straight, and...

5.1 Predicting the viscosity of a blend of components is a common problem. Both the Wright Blending Method and the ASTM Blending Method, described in this practice, may be used to solve this problem. 5.2 The inverse problem, predicating the required blend fractions of components to meet a specified...

1.1 In this standard, guidelines for measuring post-manufacturing relative density of metallic additive manufactured (AM) parts and density assessment test specimens are given. 1.2 In this guide, standard test methods commonly used to measure part relative density and details...
