1.1 This test method covers the determination of the purity of cyclohexane by gas chromatography. 1.2 This test method is applicable to the measurement of impurities in Table 1.?This test method is applicable to samples with concentrations to 400 mg/kg, but may be applicable to a wider range...

1.1 This test method covers the determination of the purity of methyl isobutyl ketone (MIBK) by gas chromatography and in addition provides a means for measuring certain impurities such as methyl isobutyl carbinol which are of interest. Impurities such as water and acidity are measured by...

This Aerospace Information Report provides general information to aircraft designers and engineers, regarding LOX, its properties, its storage and its conversion to gas. Much useful information is included herein for aircraft designers regarding important design considerations for a safe and...

1.1 This specification covers coextruded poly(vinyl chloride) (PVC) plastic pipe with a cellular core and concentric inner and outer solid layers, and is produced using a multilayer coextrusion die for nonpressure use in three series: an IPS Schedule 40 series for DWV; a PS series with an iron pipe...

1.1 This practice describes procedures for making joints suitable for pressure service with polyethylene (PE) pipe and fittings by means of electrofusion joining techniques in, but not limited to, a field environment. Other suitable electrofusion joining procedures are available from various...

1.1 This practice describes a micro-scale chamber apparatus and associated procedures for rapidly screening materials and products for their vapor-phase emissions of volatile organic compounds (VOCs) including formaldehyde and other carbonyl compounds. It is intended to complement, not replace...

1.1 This guide provides techniques that are useful for the comparison of modeled air concentrations with observed field data. Such comparisons provide a means for assessing a model's performance, for example, bias and precision or uncertainty, relative to other candidate models. Methodologies for...

1.1 This test method is used to identify and to measure the emissions of volatile organic compounds (VOCs) emitted from samples of cured spray polyurethane foam (SPF) insulation using micro-scale environmental test chambers combined with specific air sampling and analytical methods for VOCs. 1.2...

1.1 This test method covers the determination of water from 0?% to 2.0?% mass in most liquid organic chemicals, with Karl Fischer reagent, using an automated coulometric titration procedure. Use of this test method is not applicable for liquefied gas products such as Liquid Petroleum...

1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, and markings for on-site manufactured multilayer reinforced polyethylene composite pipe. It covers nominal sizes 6 in. through 36 in. (150 mm through 915 mm). These multilayered reinforced...

5.1 These measurements give semiquantitative estimates for the gas transmission of single pure gases through film and sheeting. Correlation of measured values with any given use, such as packaged contents protection, must be determined by experience. The gas transmission rate...

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...

This specification covers a premium aircraft-quality, high-alloy steel gas-atomized and HIP-consolidated in the form of bars, wire, forgings, and forging stock.

This specification covers LNG density calculation models for use in the calculation or prediction of the densities of saturated liquefied natural gas (LNG) mixtures at a specified temperature range given the pressure, temperature, and composition of the mixture. Composition restrictions for...

2.1 This test method provides a guide for evaluating the resistance of refractories in glass-melting furnace superstructures to vapor attack. This test method may also be useful for evaluating refractories in other applications where vapor attack occurs. 2.2 An electric-heated furnace is...

This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of APU (auxiliary power unit) engines. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance...

1.1 This test method covers the determination of the boiling point distribution and cut point intervals of crude oils and residues by using high temperature gas chromatography. The amount of residue (or sample recovery) is determined using an external standard. 1.2 This test method extends...

1.1 This specification, to be used in conjunction with Specification F1073, covers the principal dimensions and the mechanical requirements for manufacturing steel and aluminum individually dogged, airtight/gastight double doors for personnel access through bulkheads, complete with frames, intended...

This specification provides requirements and procedures for gas-pressure leak testing of parts.
