Soils - Moisture-Density Relations Standard Proctor Test
The present standard describes the methods of determining the relation between
the moisture content and the density of soils and soil aggregates when these
are compacted in standard moulds using 2,49 kg rammers dropped a height of 305
mm. Four methods are described herein.
NOTE 1 - The laboratory compaction tests described in this standard generally
provide good measures of optimum…
The purpose of the measuring method is to determine the residual camber height and length as a function of the load ("flattening test"). Gives some essential informations related to the parameters "contact load" and "standard camber length". Applies to cross-country skis of size 130 cm and longer.
Glass — Resistance to attack by hydrochloric acid at 100 degrees C — Flame emission or flame atomic ...
The specified method applies to pieces of glass, preferable flat but if necessary curved, but from articles of laboratory glassware. Sample pieces are subjected to an aqueous hydrochloric acid solution, and the amount of alkali metal oxides extracted per unit area is determined as a measure of the acid resistance. Apparatus, reagents, and procedure are specified.
Rubber, vulcanized — Determination of ageing characteristics by measurement of stress at a given elo...
Describes three methods of testing: A: measurements under continuous strain, B: preferred for intermittent strain, C: alternative to B under intermittent strain and laboratory conditions. For A and B a stress tester is used to record the stress at the temperature of ageing. Helpful for quality control. Measurement at differnt temperatures may be used for research. Method to be used depends on the…
Acoustics — Measurements of sound insulation in buildings and of building elements — Part 9: Laborat...
Specifies a method for measuring a quantity called the suspended ceiling normalized level difference when the sound transmitted by paths other than the required paths is negligible.
1. Scope
1.1 This Standard covers the details of construction, performance, and test for portable and stationary electrical instruments for sensing the presence of combustible gas or vapour concentrations in air, parts of which may be installed or us ed in Class I hazardous locations and gaseous mines in accordance with the Rules of the Canadian Electrical Codes, Parts I and V.
1.2…
Cross-country skis — Determination of elastic properties
Specifies the apparatus, sampling and conditioning and the procedure for laboratory measuring methods to determine the elastic properties. Applies for cross-country skis with a nominal length greater than or equal to 150 cm. Standard measurement procedures are recommended in order to ensure the comparability between measurement data determined by the manufacturers.
