Acetone for industrial use — Methods of test — Part 5: Control test with Agulhon's reagent
This control is intended essentially for the detection of alcoholic impurities in aceton. The principle consists in treatment of a test portion with Agulhon's reagent (potassium dichromate solution added to nitric acid solution) under specified conditions. The presence of certain impurities, in particular alcoholic ones, is indicated by a blue or violett coloration. International Standards…
Acetone for industrial use — Methods of test — Part 1: General
Gives general instruction and specifies the methods for the determination of density at 20 °C, the determination of dry residue after evaporation on a water bath, the measurement of colour, the determination of distillation range and the determination of water content. International Standards ISO 757/1 to ISO 757/5 cancel and replace ISO Recommendation R 757-1968, of which they constitute a…
Acetone for industrial use — Methods of test — Part 2: Determination of acidity to phenolphthalein —...
The principle of the method consists in dilution of a test portion with carbon dioxide-free water, titration of the test solution, if acid, with standard volumetric sodium hydroxide solution, using phenolphthalein as indicator. The method is applicable to products having acidities, expressed as acetic acid, equal to or greater than 0,0006 % (m/m). International Standards ISO 757/1 to ISO 757/5…
Technical drawings — Simplified representation of centre holes
This representation mode may be used particulary when it is not necessary to show the exact form and size and where the designation of standardized centre holes is sufficient for information. Annex A gives the dimensions for types R, A and B, and Annex B the proportions and dimensions of symbols.
This standard applies to dehydrated soup mixes and soup bases that can be
reconstituted for use by the addition of water. It is intended primarily for
use by Departments of the Federal Government involved with the procurement of
food.
Standard Method of Fire Test of Fire-Damper Assemblies
These requirements and methods of test apply to fire-damper
assemblies rated 3/4h, 1h, l-1/2h, 2h, or 3h for use in
air-conditioning and ventilating system ducts or openings
(without ducts) piercing horizontally or vertically oriented fire
separations where the fire separations are required to have a
fire resistance rating of not more than 4h.
1. Scope
1.1 This Standard applies to electrically operated, general- purpose valves and safety valves that are intended to be used in ordinary locations in accordance with the Canadian Electrical Code, Part I, for the control of fluids (e.g., air, gases, oils, refrigerants, steam, water, etc.), and rated 600 V and less.
For convenience, the shorter term valve is used where the same…
Alternating-Current (AC) Electrical Installations on Boats
1. Scope
1.1 This Standard covers single-phase, ac electrical installations not exceeding 250 V between conductors or 150 V to ground, on boats which may have an on-board source of electrical supply or may be connected to a source of ac electrical supply that is in accordance with the Rules of the Canadian Electrical Code, Part I.
1.2 This Standard applies to boats that are not…
Applies to flame-producing devices commonly referred to as
lighters, which though intended primarily for the ignition of
cigarettes, cigars, and pipes, may also be used to ignite other
items such as paper, candles and lanterns. They use petrochemical
derivatives as fuel. The purpose of this standard is to establish
safety standards for lighters to provide a reasonable degree of
safety in…
