Oil Fired Steam and Hot Water Boilers for Residential Use
1. Scope
1.1 This Standard applies to complete flue-connected, oil-fired steam and/or hot-water low pressure boilers, provided with automatic control devices.
1.2 This Standard applies to boilers intended for residential use having an input of less than 3 gallons per hour (US) (approximately 400,000 Btu/h).
Note: A boiler which has an input exceeding this limit may be considered…
Asphalt, Cutback, Filled, for Dampproofing and Waterproofing
Definition
1.1 this standard applies to filled cutback asphalt for use by brush or spray for dampproofing and waterproofing masonry and concrete walls below grade, and for dampproofing and waterproofing concrete floors.
Unplasticized polyvinyl chloride (PVC) fittings with plain sockets for pipes under pressure — Laying...
Contains tables with specifications of dimensions and tolerances of unplasticized PVC-fittings under pressure, fitting together with the specified nominal outside diameters of tubes according ISO 161-1. It should be used as a guide to manufacturers and users and as a basis for specific standards.
Sodium carbonate for industrial use — Determination of total soluble alkalinity — Titrimetric method
Specifies a titrimetric test method for the determination of the basicity of soluted material. The principle of the procedure consists in solution of a test portion in water, filtration of the solution and titration with a standard volumetric solution of hydrochloric acid in presence of methyl orange as indicator. Repaces ISO Recommendation R 740-1968.
Sodium carbonate for industrial use — Determination of sodium hydrogen carbonate content — Titrimetr...
The method is applicable to sodium carbonate products having a sodium hydrogen carbonate contained in a test portion into sodium carbonate by addition of a known excess of sodium hydroxide, precipitation of all the carbonate by means of barium chloride an determination of the excess of sodium hydroxide by means of a standard volumetric hydrochloric acid solution.
Glycerines for industrial use — Determination of alkalinity or acidity — Titrimetric method
The principle of the method consists in the titration of a test portion with a standard volumetric solution of hydrochloric acid or sodium hydroxide in the presence of phenolphthalein as indicator. - Replaces ISO Recommendation R 1615-1970.
Potassium chloride for industrial use — Determination of potassium content — Sodium tetraphenylborat...
The method is applicable to products having a minimum KCl content of about 95 % (m/m). The principle consists in dissolution of a test portion taken from the previously ground and sifted laboratory sample and elimination of many ammonium ions present. Precipitation of the potassium, in a slightly acid medium, by an excess of an standard volumetric sodium tetraphenylborate solution. Filtration and…
Timekeeping instruments — Wrist-chronometers with spring balance oscillator
Lays down the definition of the term "chronometer", describing the categoeries, the test programme and the acceptable minimum requirements for wrist-chronometers. Wristwatches using a tuning fork oscillator are subjected to these tests pending the availability of separate standards.
