This standard applies to chemically produced methanol with a purity of 99.85% by mass.

Attention is drawn to the fact that this Technical Report only regards recommendations which do not have any restrictive nature nor do they require the replacement of existing regulations which have proved their worth in the past. Applies only to external gear pairs with parallel axes of which the teeth of spur and helical gears are defined by the standard basic rack tooth profile in conformity…

Applies to the design of ordinary highway bridges that have spans up to 100 m and other bridges to carry pedestrian, cyclist or equestrial traffic. It deals with the general features of highway bridges and loads and forces applicable to their design considering different materials such as steel, concrete, timber and composite structures. It gives design consideration for substructures,…

1. Scope 1.1 This Standard applies to electrical aids intended to be used by physically disabled persons to facilitate their ability to communicate with others, alter the state of their environment, and to position themselves. 1.2 This Standard includes requirements relating to the safety of these aids and documentation on them, as well as recommendations of special interest to developers…

1. Scope 1.1 This Standard describes a procedure for the measurement of A-weighted sound levels in and around industrial, institutional, or commercial sites. 1.2 This Standard applies to the measurement of sounds that are essentially non-impulsive in nature. 1.3 This Standard may be used to determine: (a) Those operating areas where permitted sound levels are exceeded; (…

1. Scope 1.1 This Standard sets forth the requirements for the construction, test, and operation of permanently or cord-connected 120 V ac detertors and 12 V dc deterctors, intended for use in the home and in recreational vehicles, for the detection of fuel gases (natural gas, methane, and propane), in accordance with the Canadian Electrical Code, Part I. No other function is implied or…

1.1 Scope 1.1.1 This standard applies to propane and natural gas-fired unattended portable type infra-red heaters (see Definitions, Part III), hereinafter referred to as heaters with gas inputs up to and including 400 000 Btuh (117.23 kW). 1.1.2 The standard applies to portable unvented infra-red heaters used primarily for temporary heating purposes. 1.1.3 Portable type…

This control is intended essentially for the detection of alcoholic impurities in aceton. The principle consists in treatment of a test portion with Agulhon's reagent (potassium dichromate solution added to nitric acid solution) under specified conditions. The presence of certain impurities, in particular alcoholic ones, is indicated by a blue or violett coloration. International Standards…

Gives general instruction and specifies the methods for the determination of density at 20 °C, the determination of dry residue after evaporation on a water bath, the measurement of colour, the determination of distillation range and the determination of water content. International Standards ISO 757/1 to ISO 757/5 cancel and replace ISO Recommendation R 757-1968, of which they constitute a…

The principle of the method consists in dilution of a test portion with carbon dioxide-free water, titration of the test solution, if acid, with standard volumetric sodium hydroxide solution, using phenolphthalein as indicator. The method is applicable to products having acidities, expressed as acetic acid, equal to or greater than 0,0006 % (m/m). International Standards ISO 757/1 to ISO 757/5…
