ASTM B613-17 滑动电触点用复合材料微型电刷规范制备的标准指南

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 by 3 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.

ASTM F366-17 固定插脚和固定线缆的标准规格

1.1 This specification covers functional dimensions for fixation pins and wires. 1.2 In recognition of many broad and varied uses of such pins and wires, many options are included. A variety, but not necessarily all, of the options are illustrated in Figs. 1-3. FIG. 1 Fixation Pins and Wires Note 1: Pins and wires may be smooth shank or threaded. Note 2: Point angle and helix angle, where applicable, is as specified by the manufacturer. Note 3: On square or triangular shanks, flats are equal and corners are on the same circumference as the pin diameter. Shank diameters on pins larger than 3.2 mm may be reduced. Note 4: Optional designs, both ends pointed or point with suture hole. FIG. 2 Fixation Pin-Knowles Type Note 1: Shall be made of one piece of material; that is, not an assembly of two or more pieces. Note 2: Thread major diameter may be the same or larger than the shaft diameter. Note 3: Thread length shall be optional to suit the intended medical application. Note 4: Optional marking in this location. FIG. 3 Fixation Pin-Hagie Type Note 1: Thread major diameter may be the same or larger than

EN ISO 9151:2016 阻燃隔热防护服-暴露于火焰的热传输的测定(ISO 9151:2016,修正版本2017-03)

Dieses Dokument legt ein Verfahren für die Bestimmung des Wärmedurchgangs bei in Schutzkleidung verwendeten Materialien oder Materialkombinationen fest. Durch Vergleich der Wärmeübergangsindizes, die als Anhaltspunkt für den relativen Wärmedurchgang unter den festgelegten Prüfbedingungen dienen, kann eine Einstufung der Materialien vorgenommen werden. Der Wärmeübergangsindex sollte nicht als Maß für die angegebene Schutzdauer der geprüften Materialien unter tatsächlichen Einsatzbedingungen angesehen werden.
