Character Standards

This specification defines requirements for the data used in the tracking and traceability base-62 encoding system. It provides the format of the resultant code to characterize various components used in fuel gas piping systems. In this specification, the final output is a 16 digit alpha-numeric...

This specification covers the pigment commercially known as lampblack, which may be purchased in the dry form or as a paste in oil. The dry pigment shall be made by burning oils or tars. It shall conform to chemical compositions of ash, acetone extract, moisture and other volatile matter, and...

This specification establishes the properties and requirements for the dry pigment commercially known as chrome oxide green. The pigment shall consist of practically pure chromium sesqui-oxide without any admixture. Specimens shall be sampled and tested adequately, and shall conform to the...

5.1 Shipping regulations often require the identification of a material as either a liquid or a solid. This test method may be used to make that determination for regulatory purposes. (See also Test Method D4359.) 5.2 For liquid thermosetting resin, as cure progresses, the liquid resin becomes a...

1.1 This classification system covers the classification of rubber-grade carbon blacks by the use of a four-character nomenclature system. The first character gives some indication of the influence of the carbon black on the rate of cure of a typical rubber compound containing the...

1.1 This standard covers the classification of coals by rank, that is, according to their degree of metamorphism, or progressive alteration, in the natural series from lignite to anthracite. 1.2 This classification is applicable to coals that are composed mainly of vitrinite. Note 1: Coals rich in...

1.1 This practice presents a laboratory guide to determine the thermal resistance of pneumatically installed loose-fill building insulations for enclosed applications of the building thermal envelope behind netting at mean temperatures between?-10 and 35°C (14 to 95°F). 1.2 This practice applies to...

1.1 This classification system covers the classification of rubber-grade carbon blacks by the use of a four-character nomenclature system. The first character gives some indication of the influence of the carbon black on the rate of cure of a typical rubber compound containing the...

5.1 This test method is used for material development, quality control, and material flexural specifications. Although flexural test methods are commonly used to determine design strengths of monolithic advanced ceramics, the use of flexure test data for determining tensile or compressive...

4.1 Materials less than or equal to 15 mm (0.59 in.) in thickness shall not be tested in accordance with this test method in order to avoid complete immersion of the specimens. This type of exposure is beyond the scope of this test method. 4.2 This test method is used to assess both the short-term...

1.1 This classification system covers the classification of rubber-grade carbon blacks by the use of a four-character nomenclature system. The first character gives some indication of the influence of the carbon black on the rate of cure of a typical rubber compound containing the...

5.1 When a drop of liquid rests on the surface of a solid, and a gas is in contact with both, the forces acting at the interfaces must balance. These forces can be represented by surface energies acting in the direction of the surfaces and it follows that: where: ? = angle of contact of the edge of...

4.1 This practice covers procedures of sampling for obtaining small, clear wood specimens which, when tested in accordance with Test Methods D143 and, in conjunction with full-size product tests, will provide mechanical properties for use in deriving design properties for lumber, panels, poles,...

This SAE Standard is concerned with the geometrical irregularities of surfaces of solid materials. It established definite classifications for various degrees of roughness and waviness and for several varieties of lay. It also provides a set of symbols for use on drawings and in specifications,...

2.1 When symbolic representation is required for an item not covered in this standard, the character of the symbol shall be adequately identified and shall be subject to one interpretation only. If necessary, a note shall be attached to the symbol for further clarity. 2.2 Symbolic...

3.1 Systematic surveys provide data on shoreline, lakeshore, river bank or other terrain's character and oiling conditions from which informed planning and operational decisions can be developed with respect to cleanup (1-4).3 In particular, the data are used by decision makers to determine...

1.1 This practice provides ergonomic design criteria from a human-machine perspective for the design and construction of maritime vessels and structures and for equipment, systems, and subsystems contained therein, including vendor-purchased hardware and software. 1.1.1 The focus of these design...

5.1 The pH of peat is a useful variable in determining the solubility of minerals, the mobility of ions in the peat, and assessing the viability of the peat-plant environment. pH measurements are made in both test water and a calcium chloride solution because the pH readings in test water can be...

5.1 This test method assigns an empirical value to the relative amount, fineness, and character of clay-like material present in the test specimen. 5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of clay-like or clay-size fines in an aggregate. 5.3 This...

4.1 In order to ensure data consistency, it is important to use standardized terminology and definitions in describing oiling conditions (1)3. This guide provides a template for that purpose. 4.2 Data on oiling conditions at a shoreline are needed to provide an accurate perspective of the nature...
