Methods for measuring performance of electric toasters for household and similar purposes
States and defines the principal performance characteristics of electric toasters for household and similar purposes which are of interest to the user, and describes the standard methods for measuring these characteristics.
Amendment 1 - Methods of measurement for radio transmitters - Part 2: Bandwidth, out-of-band power a...
Refers to the ITU Radio Regulations and to the Recommendations and Reports of the CCIR. Defines spectra and bandwidths of emissions and, for spurious radiation, definitions, methods of measurements and acceptable levels.
Voltage bands for electrical installations of buildings
Applies to a.c. electrical installations of buildings supplied at a frequency not exceeding 60 Hz and at a nominal voltage up to and including 1 000 V. Defines two voltage bands: Band I covers the installations where protection against shock is provided under certain conditions by the value of voltage and the installations where the voltage is limited for operational reasons (e.g.…
Sodium chloride for industrial use — Determination of matter insoluble in water or in acid and prepa...
Insoluble substances shall be defined by the conditions described in this document. The object is not to dissolve all the impurities but only those of interest to users. The method is applicable to the analysis, carried out inaqueous medium or in acid medium. The principle consists in solution of the test portion in water, filtration, drying and weighing of the insoluble residue. Dilution of the…
The terms defined in this bilingual edition are subdivided into seven sections consisting of the composition and preparation of elements, the grain, plywood panels, defects, repair, state of surfaces and transformation. Alphabetical indices of the English and French terms are included.
Aluminium fluoride for industrial use — Determination of silica content — Spectrophotometric method ...
The method can be applied provided the phosphorus pentoxide content does not exceed 0,02 % (m/m). The principle is based on alkaline fusion of a test portion by means of a mixture of sodium carbonate and boric acid. Solution of the fused mass in excess nitric acid so that the pH of the final solution is between 0,3 and 0,5 after being diluted. Formation, in a suitable aliquot portion, of the (…
1. Scope
1.1 This Standard applies to household electric toys operating at nominal potentials of 120 volts or less, including extra low potential, and intended for use in ordinary (ie, non-hazardous) locations as defined in the Canadian Electrical Code Part I.
1.2 This Standard does not apply to battery operated toys:
(a) having a battery of a non-rechargeable (primary) type; and…
Fibre building boards — Determination of bending strength
Applies to fibre building boards as defined in ISO 818. The specified method is based on the principle that a specimen supported in two points is loaded in its centre until rupture. The bending strength is calculated from this load, the distance between the supports, and the width and thickness of the specimen.
Fibre building boards — Hard and medium boards — Determination of water absorption and of swelling i...
Covers sheet materials as classified and defined in ISO 818. The specified method includes the calculation of the increase in mass and thickness. Apparatus, sampling and preparation of specimens, and testing are described.
Two methods are defined and the symbols specified as shown in the figures. The direct orthogonal projection is symbolized by two parallel arrows running vertically to a dash-and-dot line, and the mirror-inverted orthogonal projection by two parallel double arrows running vertically to a dash-and-dot line.
