Chemical products for industrial use — General method for determination of traces of sulphur compoun...
Describes a method based on prior conversion of the sulphur compounds in a test portion to sulphate, if required, and reduction of the sulphate ions ti hydrogen sulphide by a mixture of hydriodic and phosphinic acids in the presence of hydrochloric acid. The hydrogen sulphide is entrained in a current of nitrogen and absorbed in a solution of sodium hydroxide in aqueous acetone, followed by…
The Standard specifies certain characteristics of the oil. The oil shall be clear and almost colourless to pale yellow, the odour characteristic, recalling cineole. The relative density at 20/20 °C has to ly between 0,906 and 0,925 and the refractive index at 20 °C between 1,4590 and 1,4670. The optical rotation shall range from 0 to + 10 . 1 volume of the oil shall not require more than 5…
1. Scope
1.1 This Standard provides minimum requirements for the material characteristics and the fabrication of wood frames for doors with or without attached wood frames, i.e., sidelights and transoms.
Solid Mild Steel Filler Metals for Gas Shielded Arc Welding
1. Scope
1.1 This Standard prescribes requirements for solid mild steel filler metals*
for use with the Gas Metal-Arc (GMAW) process and also the Gas Tungsten Arc
(GTAW) and Plasma Arc Welding (PAW) processes.
This Standard is not intended to cover submerged-arc welding electrodes.
*When used for GMAW the filler metal is referred to as electrodes;
When used for GTAW and PAW the…
Bare Mild Steel Electrodes and Fluxes for Submerged-Arc Welding
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.
Vapor Barrier, Sheet, for Use in Building Construction
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…
Steel and cast iron — Determination of sulfur content — Gravimetric method
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.
