ASTM Standards

1.1 These test methods cover plant manufacturing proce-dures for measuring the thickness of flat sandwich cores.Permissible core material forms include those with continuous bonding surfaces (such as balsa wood and foams) as well as those with discontinuous bonding surfaces (such as honey-comb). The two test methods covered include the following: 1.1.1 Test Method A—Roller-Type Thickness […]

1.1 This test method covers the determination of specific gravity of fired ceramic whiteware materials under prescribed conditions. N OTE 1—This test method is not applicable to materials attacked by water.

1.1 These test methods cover the determination of the fineness of frit in wet- or dry-milled porcelain enamels and other ceramic coatings for metals by means of the No. 200 (75-µm) or No. 325 (45-µm) sieve.

1.1 This test method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure. 1.2 This test method is intended for use with concretes and mortars made with relatively dense aggregates for which the aggregate correction factor can be satisfactorily determined

1.1 This lest method supplements Test Method C201, and shall be used in conjunction with that test method to determine the thermal conductivity of insulating firebrick. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information

1.1 This standard is a compilation of definitions of terms as they are used in standards under the jurisdiction of Committee C09. 1.2 Other terminology under the jurisdiction of Committee :C09 is included in two specialized standards. Terms relating to constituents of concrete aggregates are defined in Descriptive Nomenclature C294. Terms relating to constiwents of

1.1 These test methods cover the tests for determining the absorption and bulk specific gravity of all types of dimension stone, except slate. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system

1.1 This specification covers reinforced concrete pipe in-tended to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts. 1.2 This specification is the inch-pound companion to Specification C76M; therefore, no SI equivalents are presented in this specification. Reinforced concrete pipe that conform to the requirements of

1.1 These test methods cover procedures for the sampling and testing of brick and structural clay tile. Although not ncessarily applicable to all types of units, tests include modulus of rupture, compressive strength, absorption, satura-tion cofficient, ffct of freezing and thawing, eflorescence, initial rate of absorption and determination of weight, size, warpage, length change. and

1.1 This specification covers gypsum casting plaster and gypsum molding plaster materials consisting essentially of calcined gypsum. 1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall
