1. OBJECT AND SCOPE OF APPLICATIOn The present standard describes the method to determine the relation between the moisture content and the density of soils and soil aggregates when these are compacted in standard moulds using 4,54 kg rammers dropped a height of 457 mm. Four methods are described herein. NOTE 1 - The laboratory compaction tests described in this standard generally…

1. OBJECT AND SCOPE OF APPLICATIOn 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…

1.1 Outlines the details of construction, marking, and testing of portable electrical instruments for sensing the presence of toxic gas(es) and/or oxygen concentrations in air. These instruments may be used in Class I hazardous locations and gaseous mines in accordance with the Rules of the Canadian Electrical Codes, Parts I and II. 1.2 This Standard applies to battery-operated…

Applies to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of condenser microphones having the same mechanical dimensions or specifies a primary method of determining the pressure sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure. This publication supersedes IEC 60327.

Scope Z217.1 1.1 This practice outlines a method for the determination of the dilute solution viscosity of polystyrene products in tetrahydrofuran (THF). It is applicable to nondegraded and photodegraded polystyrene samples. It is used for the determination of relative viscosity (viscosity ratio), inherent viscosity (logarithmic viscosity number), intrinsic viscosity (limiting…

1. Scope 1.1 This method determines the degradation of polystyrene foams by measuring mass loss due to a combination of abrasion and impact produced by a laboratory tumbling device. 1.2 The values stated in metric (SI) units are to be regarded as the standard. The values in parentheses are provided for information only. 1.3 This Standard does not purport to address all of the…

Applies to: testing laboratories, including those providing a calibration service; suppliers of products or services; other organizations where measurement is used to demonstrate compliance with specified requirements.

Applies to building elements, excluding windows and doors, with an area of less than 1 m^2 and which transmit sound between two adjacent rooms or between one room and the open air independently of the adjoining building elements. Annexes A, B and C are for information only.

Describes the equipment, the test facility, the specimen, the test procedure, the calculation of the sound attenuation, the precision, the expression of results, and the contents of the test report. Annexes A, B and C are for information only.

Provides a method for measuring the sound-pressure level due to liquid flow through a control valve, and the characteristic increase in noise due to cavitation.
