Replacement Burners and Replacement Combustion Heads for Residential Oil
Burners
1. Scope
1.1 This Standard applies to the provision of alternative combustion heads or
end-cones intended to be fitted to currently in-service residential gun-type
burners for the purpose of improving combustion efficiency.
1.2 This Standard also applies to the provision of complete residential
gun-type burners intended for the purpose of improving combustion efficiency.
1. Scope
1.1 This Standard applies to the continuous measurement of ozone in air.
1.2 This Standard sets forth the chemiluminescence method for the measurement of concentrations of ozone between 2 µg·m-3 and 10 mg·m-3 at 25°C and 101.3 kPa (approximately 0.001 ppm v/v and 5 ppm v/v).
Notes:
(1) All concentrations referred to throughout this Standard are based on a temperature…
Specifies requirements relating to the performance and safety of
all oxygen analyzers or monitors intended for measuring oxygen
levels in a patient breathing mixture. It addresses in particular
the safety of sensor elements and the accuracy of the analyzer.
Requirements pertaining to construction, inspection,
sterilization or disinfection, servicing, disclosure of
information by the…
Fertilizers — Determination of ammoniacal nitrogen content — Titrimetric method after distillation
The method consists in distilling of the ammonia from an alkaline solution, absorbing in an excess of standard volumetric sulphuric acid solution and back-titrating with standard volumetric sodium hydroxide solution. It is applicable only in the absence of urea or its derivatives, of cyanamide and of organic nitrogenous compounds.
Textiles — Determination of resistance to surface wetting (spray test) of fabrics
The method is applicable to all fabrics which may or may not have been given a water-resistant or water-repellent finish. It is not intended to predict the rain penetration resistance of fabrics, since it does not measure penetration of water through the fabric. Before testing carried out the specimen shall be conditioned for at least 24 h in the standard atmosphere for testing textiles.
Textile fibres — Determination of length and length distribution of staple fibres (by measurement of...
Specifies three methods for determination - method A: on a straightened fibre on a graduated rule, under a light tension applied with the aid of forceps and grease; - method B: measurement, using an opisometer, of the length of the image of fibre enlarged by projection on a screen; - method C: by use of a semi-mechanical device. - Intended to replace two existing International Standard, ISO 270…
Specifies the marking system recommended to the manufacturer so as to reduce risks of incompatibility between components of bicycles produced according to new ISO Standards and traditional components. This problem of selection of the appropriate component will make itself felt above all at the level of the repair of bicycles and the distribution of spare parts; it will be necessary for this…
Ground Motion Determination for Seismic Qualification of CANDU Nuclear Power
Plants
1. Scope
1.1 This Standard describes the investigations required to obtain the seismological and geological information necessary to determine, for a proposed CANDU nuclear power plant site, the seismic ground motion that will be utilized in seismic qualification of safety-related plant structures and systems, and the potential for seismically induced phenomena that may have a direct or…
