1.1 This specification covers the material characteristics,physical requirements, and sampling appropriate to the selec-tion of slate for use as roof shingles. 1.2 Slates not included in this specification are those con-taining soft carbonaceous ribbons. The wide variation in physical properties and composition of such ribbon slates render their service life uncertain under some conditions of […]

1.1 This test method 2 covers the determination of the transverse rupture strength of cemented carbides. 1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values in parentheses are provided for information only.

1.1 This practice summarizes well-known, generally practi-cal methods for producing adherent electrodeposits of nickel on nickel. 1.2 Electrodeposits of nickel on nickel are produced, for example, to improve the performance ofdecorative coatings, to reclaim electroplated parts that are defective, and to resume nickel electroplating after interruptions in processing. Interrup-tions may be deliberate, for example, to

1.1 This practice is intended to assist electroplaters inestablishing and maintaining a satisfactory pre-electroplatingcycle for malleable iron, gray iron, nodular iron, and white ironcastings. It is also intended to indicate certain foundry practiceswhich will facilitate subsequent finishing. Most ofthe practicesthat follow have been based on experience with malleable andgray iron. However, since they are related

1.1 This test method covers the determination of density for powder metallurgy (PM) materials containing less than tWo percent porosity and for cemented carbides. This test method is based on the water displacement method. NoreE 1- -A test specimen that gpains mass when immersed in wacer indicmes the specimen cootains surface connected porosity. Unsealed surfaoe

1.1 This specification establishes the requirements for seam-less copper tube intended for use in the connection, repairs, or alternations of air conditioning or refrigeration units in the field.

1.1 This test method specifies procedures for the metallo-graphic determination of apparent porosity in cemented car-bides. NOTE 1- -The term “apparent porosity” is construed to mean all microstructures observed on a properly prepared, unetched surface,including structures resulting from uncombined carbon, non-metallic inclusions, etc.. as well as true, inherent porosity.

1.1 This specification2 covers annealed titanium and tita-nium alloy strip, sheet, and plate as follows 1.1.1 Grade 1- _UNS R50250. Unalloyed titanium, 1.1.2 Grade 2- _UNS R50400. Unalloyed titanium,

1.1 This test method covers the procedure for determining the cross-sectional area of stranded conductors by the mass method. 1.2 The values stated in inch-pound or SI units are to be regarded separately as the standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other.
