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.

1.1 This guide is intended as an aid in establishing and maintaining a procedure for preparing zine aloy die castings for electroplating and conversion coatings. It is primarily intended for the preparation of Alloys UNS Z33521 (AG-40A) and UNS Z35530 (AC-41A) (Specifcation B86) for electro-plating with copper, nickel, and chromium (Specification B456).

1.1 This specification covers tinned hard-drawn and medium-hard-drawn round copper wire for electrical purposes. 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 only and are not considered standard.

1.1 This guide is intended as an aid in establishing and maintaining a preparatory cycle for electroplating on high-carbon steel (Note I ) producing a minimum of hydrogen embrittlement and maximum adhesion of the electrodeposited metal. For the purpose of this guide, steels containing 0.35 % of carbon or more, and case-hardened low-carbon steel, are

1.1 This specification covers bare hard-drawn round copper-clad steel wire for electrical purposes (Note 1). Nom 1- Wire ordered to this specifcation is not intended for redrawing. If wire is desired for this purpose, consult the manufacturer.

1.1 These practices cover sampling methods used to collect a small quantity of metal powder that is as representative of the entire starting material as possible, and details the procedures that are recommended for reducing this quantity into smaller test portions on which chemical, physical, and mechanical property data may be determined.

1.1 This specification covers the requirements for electrode-posited coatings of lead and lead-tin alloys on steel and ferrous alloys. The coatings of lead-tin alloys are those that range in tin content up to but not exceeding 15 mass %. The coatings ranging between 3 and 15 mass % in tin content are known also as“terme”
