This guide defines the criteria for composition, properties, and other requirements for miniature brushes of composite materials containing a matrix of one or more conducting metallic elements or alloys and one or more lubricating lamellar solids intended for sliding electric contacts. Each constituent of the material should be listed individually by weight percent including tolerances using any analytical technique while the apparent density for the material should be defined using the measurement and weight method. The resistivity; Rockwell superficial hardness, transverse strength, and shear strength; and microstructural properties such as cracks and defects should also be defined and should conform to the required electrical, mechanical, and structural properties of the brush materials.1.1 This guide defines the criteria for composition, properties, and other requirements for brushes containing a matrix of one or more conducting metallic elements or alloys and one or more lubricating lamellar solids.1.2 The resulting specification is intended for use where the size (for example, 5 mm by 3 mm by 2 mm), shape, or other factors preclude the determination of properties on specimens of the bulk material from which individual brushes are made.1.3 The requirements recommended herein have been found to be desirable for most brush material composites. Care must be taken in preparing a specification for a pre-existing material that imposition of one or more provisions herein does not alter the material or its performance.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This practice explains the procedure for identifying standard grades and types of flat-rolled electrical steels in ASTM electrical steel specifications. This practice applies to flat-rolled magnetically soft irons and steel such as low-carbon steels and alloys of iron with silicon, aluminum, and so forth produced to a specified thickness and maximum value of core loss. These designations are intended to replace the old AISI M designations which are no longer supported. The practice also has a cross-reference between thickness and electrical sheet gage number.1.1 This practice covers the procedure for designating (within ASTM specifications) standard grades of flat-rolled electrical steels made to specified maximum values of specific core loss. This practice applies to magnetically soft irons and steel (low-carbon steels and alloys of iron with silicon, aluminum, and other alloying elements) where a core loss measurement at a stated peak value of alternating induction and a stated frequency, such as 1.5 T (15 kG) and 60 Hz, is normally used to grade the material. This practice also applies when some other property is specified (or a different induction or frequency, or both) as the limiting characteristic, provided the material also meets all the requirements of the ASTM specification.1.2 Individual specifications that are in conformity with this practice are Specifications A677, A683, A726, A876, and A1086.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This classification system covers segmented block copolyester elastomers suitable for molding and extrusion.1.2 This classification system allows for the use of segmented block copolyesther elastomers that are recycled provided that the requirements as stated in this classification system are met. The proportions of recycled material used, as well as the nature and amount of any contaminant, however, cannot be covered practically in this specification.1.3 The properties included in this classification system are those required to identify the compositions covered. It is possible that there are other requirements necessary to identify particular characteristics important to specialized applications. One way of specifying them is by using the suffixes as given in Section 5.1.4 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection is best made by those having expertise in the plastic field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this classification system.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 The following precautionary caveat pertains only to the test methods portion, Section 11, of this classification system. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: This standard, ISO 14910-1, and ISO 14910-2 address the same subject matter, but differ in technical content.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This practice covers specific requirements for incorporating quality control procedures into an ASTM test method. 1.2 The requirements in this practice should be looked upon as the primary requirements for quality control of a specific test method. In many cases, it may be desirable to implement additional quality control criteria to ensure the desired quality of data. The guidelines are intended to be incorporated into a comprehensive approach to quality assurance and quality control that include the more general approaches described in Practices D3856 and D4210. 1.3 The specific requirements in this practice may not be appropriate for all test methods. They will vary depending on the type of test method used as well as the analyte being determined and the sample matrix being analyzed. 1.4 This practice is for use with quantitative test methods and may not be applicable to qualitative test methods. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
