1.1 This guide describes the determination of approximate optimum SO 3 for maximum performance as a result of substi-tuting calcium sulfate for a portion of the cement. 1.2 This guide refers to the sulfur trioxide (SO 3 ) content of the cement only. Slag cements and occasionally other hydraulic cements can contain sulfide or other […]

1.1 This test method 2 covers the determination and evalua-tion of the resistance of overglaze decorations on ceramic whitewares to attack by normal household soaps and liquid detergents under normal household conditions. 1.2 This test method applies primarily to overglaze decora-tions applied to dinnerware for domestic use wherein house-hold soaps and detergents are used for

1.1 This specifiation covers reinforced elilically shaped concrete pipe to be used for the conveyance of sewage,industrial wastes, and storm water, and for the construction of culverts.

1.1 This test method covers procedures for measuring the corner, diagonal, and edge warpages of the following catego-ries of ceramic tile: 1.1.1 Square Tile, 2 by 2 in. (51 by 51 mm) or larger, that are nominally flat, of uniform overall thickness, and have a smooth face of one of the types: unglazed, bright glazed,

1.1 This test method covers the determination of the creep characteristics and creep rate of flat sandwich constructions loaded in flexure, at any desired temperature. 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 honeycomb).

1.1 This specification covers the manufacture and purchase requirements of products used for the assembly and construc-tion of circular vertical precast reinforced concrete manholes and structures used in sewer, drainage, and water works. 1.2 Part I, Sections 1 – 11, of this specification presents general requirements and requirements that are common to each precast concrete

1.1 These test methods cover the physical testing of joint compound, paper joint tape, glass-mesh joint tape, and an assembly of joint compound and paper joint tape. 1.1.1 Joint treatment materials are specified in Specification C475/C475M.

1.1 This test method covers the determination ofthe crazing resistance of fired glazed whitewares using the autoclave treatment and under the conditions specified in this test method. 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

1.1 This test method covers determination of the mass loss of preformed block-type and preformed pipe-covering-type thermal insulation as a result of a combination of abrasion and impact produced by a laboratory tumbling mechanism. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions

1.1 This lest method covers the determination of the perfor-mance of commercial sizes of both block and pipe forms of thermal insulating materials when exposed to simulated hot-surface application condions. The term “hot-surface perfor-mance” has reference to a simulated use-temperalure test in which the heated testing surface is in a horizontal position.
