Standard Practice for Making Press-Connect Joints with Seamless Copper and Copper Alloy Tube and Press Fittings
Abstract: 5.1 The techniques described herein are used to produce leak-tight press-connect joints between copper and copper alloy tube and fittings either in shop operations or the field. Operator or mechanic’s skill and knowledge ... -
Standard Specification for Quicklime for Structural Purposes
Abstract: This specification covers all classes of quicklime such as crushed lime, granular lime, ground lime, lump lime, pebble lime, and pulverized lime, used for structural purposes. The quicklime shall conform to the chemical ... -
Standard Guide for the Appropriate Uses of Hand Held XRF Devices to Evaluate and Classify Copper-Bearing Scrap Materials
Abstract: 5.1 This guide is intended for the identification and classification of copper-bearing scrap materials. Such identification and classification may include grading for commercial purposes, determining compliance (within the ... -
Standard Guide for Obtaining a Representative Sample of Copper and Copper Alloy in Particulate Form for Analysis
Abstract: 4.1 This guide is intended primarily for the sampling of particulated copper and copper alloy material for compliance with compositional specification requirements. “Granulated chops” commonly refers to wire and cable, but ... -
Standard Test Method for Measurement of Thickness of Chromium and Chromium Alloy Deposits by the Coulometric/White Light Interferometry
Abstract: 4.1 Measurement of the thickness of a coating is essential to assessing its utility and cost. 4.2 The coulometric method destroys the coating over a very small (about 0.1 cm2) test area. Therefore, its use is limited to ... -
Standard Test Method for Methylene Blue Index of Clay
Abstract: 3.1 Tests run on many clays generally indicate that a straight-line relationship exists between the methylene blue index (MBI) and such fundamental clay properties as cation exchange capacity, dry bond strength, and casting ... -
Standard Practice for Sampling Aluminum Ingots, Billets, Castings and Finished or Semi-Finished Wrought Aluminum Products for Compositional Analysis
Abstract: 5.1 Products covered by this practice are unwrought aluminum ingots, billets, and castings and unclad wrought aluminum sheet, plate, rolled or cold finished extrusions, extruded profiles, wire, rod and bar. Machined wrought ... -
Standard Specification for Titanium and Titanium Alloy Ingots
Abstract: This specification covers titanium and titanium alloy ingots. The chemical requirements and permissible variations in product analysis are specified. This standard does not claim to address all of the safety concerns, if ... -
Standard Test Methods for Oil Content, Oil-Impregnation Efficiency, and Surface-Connected Porosity of Sintered Powder Metallurgy (PM) Products Using Archimedes’ Principle
Abstract: 5.1 Oil content values are generally contained in specifications for oil-impregnated PM bearings. 5.2 The oil-impregnation efficiency provides an indication of how well the as-received parts had been impregnated. 5.3 The ... -
Standard Specification for Heat Resistant Aluminum-Zirconium Alloy Wire for Electrical Purposes
Abstract: The specification covers heat resistant aluminum-zirconium alloy round wire for electrical purposes. There is a family of aluminum-zirconium alloys that are used for heat resistance, which differ by zirconium content, ... -
Standard Test Method for Determination of Coercivity (Hcs) of Cemented Carbides
Abstract: 5.1 Measurement of coercivity provides a relative comparison of carbide grain size, binder content, and possibly carbon deficiency for a given graded carbide material or product, and may be employed as a non-destructive ... -
Standard Terminology Relating to Non-ferrous Metals and Alloys
Abstract: 2.1 The terms defined in this document are generic in respect to the standards under the jurisdiction of Committee B02 on Nonferrous Metals and Alloys. The same terms may have different definitions in other ASTM technical ... -
Standard Specification for Metal Injection Molded (MIM) Materials
Abstract: This specification covers ferrous metal injection molded (MIM) materials fabricated by mixing elemental or pre-alloyed metal powders with binders, injecting into a mold, debinding, and sintering with or without subsequent ... -
Standard Test Method for Determination of Magnetic Saturation (Ms) of Cemented Carbides
Abstract: 5.1 This test method allows the nondestructive measurement of the magnetic fraction of the binder phase in cemented carbide powder materials and sintered product, and may be used as an indirect measure of the carbon level ... -
Standard Specification for Pre-Patinated Copper for Architectural Applications
Abstract: This specification establishes of the requirements for pre-patinated (artificially aged) copper sheets and strips in ounce-weight thicknesses supplied in flat lengths for roofing, flashing, and other architectural applications. ... -
Standard Test Method for Hydrophobic Contamination on Glass by Contact Angle Measurement
Abstract: 5.1 The contact angle test is nondestructive and may be used for control and evaluation of processes for the removal of hydrophobic contaminants. The test may also be used for the detection and control of hydrophobic ... -
