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.
Specification of the dimensional and other requirements, that are considered important to ensure the interchangeability of these instruments, for the nine most commonly used steel cutters. Other characteristics of cutters, for example spiralled blades or cross-cut, are not included. Attention is drawn to ISO 6360 which specifies a 15 digit number for the identification of all types of these…
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.

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.
Laboratory glassware — Volumetric glassware — Methods for use and testing of capacity
The general procedure is based upon a determination of volume of water in the vessel. The described procedures are applicable to ware with capacities in the range of 0,1 to 2000 ml. These include transfer and one-mark pipettes without subdivision, graduated measuring pipettes and dilution pipettes, burettes and volumetric flasks. The apparatus, materials, accuracy, setting of the meniscus,…
Applies to both fixed and operable windows which are intended to
be factory-assembled and installed in buildings. The
requirements also apply to operable windows installed in prime
doors, and to door transoms and door side-lights.
