1. Scope 1.1 This Standard prescribes requirements for bare mild steel electrodes and fluxes for submerged-arc-welding of mild and low-alloy steels. 1.2 Where reference is made to other publications, such reference shall be considered to refer to that edition of such publication and any revisions thereto approved by the organization issuing that publication.

Covers the performance requirements of two types of sheet materials suitable for use in controlling the movement of water vapor in building construction. Material to this standard is primarily intended for use in above-grade building construction and on the interior of below grade building construction. This standard is not intended to apply to vapor barrier materials for use under concrete…

The method is applicable to products having sulphur contents greater than 0,003 % (m/m). It is particularly suitable as a reference method for the standardization of samples on which certified standard values are to be established. Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.

Applicable to products having contents, expressed as sulphate2- , between 0.03 % (m/m) and 0.5 % (m/m). Reduction of the compounds to hydrogen sulphide by heating with a mixture of hydriodic and hypophosphorus acids in the presence of hydrochloric acid. Entrainment of the hydrogen sulphide in a flow of nitrogen and absorption in an excess of ammoniacal cadmium acetate solution. Liberation of the…

Includes the dimensions of relays with a rated breaking capacity equal to 2 A or 3 A. Applies to the relays currently used for aircraft electrical power systems. The characteristics of these relays will be defined in a future International Standard.

Applicable to the quantitative determination of contents of benzene, C8 aromatics and aliphatics up to n-nonane in the range between 0.01 % (m/m) and 1.00 % (m/m). Alternatives that will give equivalent results may also be used. Addition of a known amount of intgernal standard to a test portion and introduction of an aliquot portion of this mixture into a separating column. Sweeping of the…

1. Scope 1.1 This Standard applies to the measurement of the concentration of sulphur dioxide in air. 1.2 This Standard sets forth the Pararosaniline Colorimetric Procedure based on the West-Gaeke Method as the reference method for the measurement of sulphur dioxide in the range 25 to 1000 µg·m-3 at 25°C and 101.3 kPa. Note. All concentrations referred to throughout this Standard…

1. Scope 1.1 This standard applies to two types of new tires for use on passenger cars and some trucks. The tires are of the bias ply or radial ply types.

1. Scope 1.1 This standard applies to pneumatic tires, both tube and tubeless types, for mounting on agricultural type vehicles.

1. Scope 1.1 This standard applies to pneumatic tires to which studs have been applied to improve traction and braking performance on icy surfaces.
