Recommended Practice for the Prediction of Sound Pressure Levels in Large Rooms Containing Sound Sou...
1. Scope
1.1 This Recommended Practice describes a procedure for the prediction of sound pressure levels in a large room containing a number of sound sources. This procedure may be used to compute A-weighted, octave, or fractional octave band sound pressure levels over continuous contours, or at specific points, to predict:
(a) Sound pressure levels at the design stage;
(b) The…
Standard for Hose Materials for Conducting Flammable and Combustible Liquids
Sets forth requirements for hose material for conducting
flammable and combustible liquids handled at temperatures within
the range of -40°C to +50°C, primarily into the fuel storage tank
of the end use vehicle.
Standard Method of Test for Surface Burning Characteristics of Building
Materials and Assemblies
Covers the method of test for determining the comparative burning
characteristics of the material or assembly under test and is
applicable to any type of building material that by its own
structural qualities, is capable of supporting itself in position
in the test furnace.
Standard Method of Test for Surface Burning Characteristics of Flooring,
Floor Covering and Miscel...
Covers the method of test for determining the comparative burning
characteristics of the material or assembly under test and is
applicable to the finished surface or covering of a floor
extending to a maximum depth of 65 mm.
Layouts for standards — Part 4: Standard for atomic absorption spectrometric analysis
Establishes a layout for standard methods of analysis and gives some recommendations for their presentation and wording. This layout involves the use of appropriate terminology, indicated in ISO 6955. Supplements ISO 6956, which summarizes the principle of atomic absorption.
Asbestos-cement products — Part 1: Corrugated sheets and fittings for roofing and cladding
Specifies the characteristics or straight asbestos-cement corrugated sheets and their asbestos-cement fittings to be used for roofing and cladding. Specifies also the checking of these characteristics as well as marking and conditions of acceptance. By agreement between manufacturer and purchaser certain requiremants can apply to curved corrugates sheets. Is not applicable to asymmetrical section…
Surface active agents — Determination of mineral sulfate content — Titrimetric method
A buffered acetonic solution of a test portion is titrated with a standard volumetric lead(II) nitrate solution in the presence of dithizone as indicator. The method is applicable to anionic surface active agents, containing sodium, ammonium and alkanolamine sulphates. It is not applicable to products containing other compounds such as phosphates or large amounts of chloride nor is it applicable…
Surface active agents — Determination of the power to disperse calcium soap — Acidimetric method (Mo...
A 0,5 % (m/m) aqueous soap solution is prepared, and after maintaining this at testing temperature for 24 h, an aliquot portion of this solution is taken. This aliquot portion is mixed with a dilute solution of the dispersing agent (surface active agent) and subsequently with a specified volume of water of known calcium hardness. The mixture is maintained for 1 h at the testing temperature and…
