This document specifies the principle, equipment, test pieces, procedures, result expression and test report of test methods for thermal shock resistance of refractories. Three test methods are included in this document. Each one is applicable to a different product type and their test results are not comparable. The test method, the test temperature and the test condition are intended to be…

This standard applies to three grades of aviation turbine fuel (military grades F-34, F-37 as its equivalent, and F-44) consisting of conventional hydrocarbons, synthetic hydrocarbons, naturally occurring non-hydrocarbons and additives as specified herein. Grade F-34 is a kerosene-type aviation turbine fuel, and grade F-44 is a high-flash kerosene-type aviation turbine fuel. Kerosene-type…

This standard applies to two grades of kerosene-type aviation turbine fuel (grades JET A and JET A-1), consisting of conventional hydrocarbons, synthetic hydrocarbons, naturally occurring non-hydrocarbons and additives as specified herein. The fuels are normally used in civil aviation operations. The two grades differ only in freezing point. Grade JET A has a maximum freezing point of -40°C…

This test method describes two procedures for the visual haze rating or appearance of contamination of liquid fuels with an ASTM colour rating of 5 or less, and a cloud point below the reported temperature of the test. The testing and evaluation of a product against this method requires the use of materials and/or equipment that could be hazardous. This document does not purport to address all…

This document specifies requirements for the evaluation of stent systems (vascular stents and delivery systems) and requirements with respect to nomenclature, design attributes and information supplied by the manufacturer, based upon current medical knowledge. Guidance for the development of in vitro test methods is included in Annex D. This document is supplemental to ISO 14630, which specifies…

This document specifies requirements for the characterization of a liquid chemical sterilizing agent and for the development, validation, process control and monitoring of sterilization by liquid chemical sterilizing agents of single-use medical devices comprising, in whole or in part, materials of animal origin. This document covers the control of risks arising from contamination with bacteria…

1.1 This Standard covers the refurbishing of shop fabricated tanks built to nationally recognized Standards listed in Tank Eligibility, Sections 12 and 18. NOTE: In the context of this Standard, refurbishing refers to repairs to, and a limited set of modifications of, tanks using materials at least equivalent to those used in the original manufacture and does not include retrofit. Refer to…

1 Scope 1.1 This Standard applies to electric supply and communication lines and equipment located entirely outside of buildings and fenced supply stations and buildings, and also where the installations or equipment are inside buildings or sections of buildings where they are employed by a utility of a) an electric system; b) a communication system; or c) a community antenna distribution…

IEC 60749-30:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60749-30:2020 establishes a standard procedure for determining the preconditioning of non-hermetic surface mount…

IEC 60749-30:2020 establishes a standard procedure for determining the preconditioning of non-hermetic surface mount devices (SMDs) prior to reliability testing. The test method defines the preconditioning flow for non-hermetic solid-state SMDs representative of a typical industry multiple solder reflow operation. These SMDs are subjected to the appropriate preconditioning sequence described in…
