4.1 This practice is useful for preparing extracts from fire debris for subsequent analysis by gas chromatography-mass spectrometry (see Test Method E1618). 4.2 This practice is useful to reduce potential fractionation during separation, such as when attempting to distinguish between various grades...
This SAE Aerospace Recommended Practice will serve as a practical resource that offers guidance to both the machine operator and process engineer for isolating the source(s) of non-repeatability in measured unbalance data. The content of this standard addresses: Machine capability to achieve...
4.1 Helium is introduced into metals as a consequence of nuclear reactions, such as (n, a), or by the injection of helium into metals from the plasma in fusion reactors. The characterization of the effect of helium on the properties of metals using direct irradiation methods may be impractical...
5.1 During preconstruction and construction evaluations, use of these test methods establishes specific and overall performance characteristics for the mortar system. 5.2 Preconstruction testing of mortars prebatched by weight provides information for the selection of the individual mortar system...
This specification establishes the composition and physical properties of rigid polyimide cellular foams intended for use as thermal and sound-isolating insulation in commercial and industrial environments. The polyimide insulations covered are classified into three types (Types I, II, and...
1.1 This practice describes the determination of the relative actinic effects of individual spectral bands of an exposure source on a material. The activation spectrum is specific to the light source to which the material is exposed to obtain the activation spectrum. A light source with a different...
5.1 This test method is a standard procedure for determining the resistance to water penetration under uniform or cyclic static air pressure differences of installed exterior windows, skylights, curtain walls, and doors. The air-pressure differences acting across a building envelope vary greatly....
1.1 This test method covers the reverberation room measurement of the noise reduction of sound-isolating enclosures. 1.2 The noise isolation class may be determined from the noise reduction measured in accordance with this test method. 1.3 This standard does not purport to address all of the...
5.1 The vacuum, bubble test method, as described in Test Method D3078, and various other leak detection methods described elsewhere (Test Method D4991, Guide E432, Test Method E493, Test Method E498, Test Method E499, and Test Method E1603) have been successfully used widely in various industries...
1.1 This test method covers the analysis of cannabinoids in cannabis products by gas chromatography (GC) and flame ionization detection (FID). 1.2 This test method is applicable to cannabis raw materials and resin cannabis products as defined in Guide D8245, including those from hemp. Such material...

5.1 This test method is a standard procedure for determining air leakage characteristics under specified air pressure differences. Note 1: The air pressure differences acting across a building envelope vary greatly. The slope of the roof and other factors affecting air pressure differences and the...
1.1 This practice covers a centrifugation cell adhesion assay that can be used to detect changes in adhesive characteristics of cells with passage or treatments. This approach measures the force required to detach cells from a substrate. Adhesion, among many variables, may vary due to changes in...
5.1 Providing speech privacy in open-plan spaces depends upon many factors, the most significant of which are the following: (1) the shadow zone of part-height space dividers and the diffraction of sound from the edges of space dividers; (2) the primary sound reflective properties of the ceiling...
This document specifies the requirements for and provides guidance on the specification, selection, qualification, bio-decontamination,
5.1 If required by the authority having jurisdiction, pressurized gaseous testing media leak testing is conducted after installation to discover and correct or repair leaks or faults in a newly constructed or modified PA12 pressure piping system before placing the system in service. Leakage or...
5.1 In order to demonstrate conformance to regulatory requirements and support the post-closure repository performance assessment information is required about the attributes, characteristics, and behavior of the SNF. These properties of the SNF in turn support the transport, interim storage, and...
1.1 This specification covers materials, structural design, physical dimensions and manufacturing requirements for monolithic or sectional corrugated high density polyethylene (HDPE) water quality units with volumes greater than or equal to 86 ft3 or 640 gal (2400 L). 1.2 The corrugated HDPE water...
5.1 If required by the authority having jurisdiction, hydrostatic pressure leak testing may be conducted to discover and correct leaks or faults in a newly constructed or modified polyethylene or crosslinked polyethylene pressure piping system before placing the system in service. Leakage or faults...
This part of IEC 61753 contains the minimum test and measurement requirements and severities which a fibre optic isolator as specified by IEC 61202-1 satisfies in order to be categorized as meeting the requirements of isolators used in controlled environments as specified in IEC...
