The requirements for basic series and sub-series of glass hydrometers of constant mass without built-in thermometer are specified. They are graduated to indicate density at 20 degrees centigrade and 15 degrees centigrade, respectively. Standard categories of surface tension are tabled in annex A, recommended stem diameters in annex B.

After incineration of the product at 525 +/- 25 degrees centigrade the method consists in a) in the case of total ash: addition of an excess of standard volumetric sulphuric acid solution and back titration with standard volumetric sodium hydroxide solution, b) in the case of water-soluble ash: extraction of the ash with hot water and neutralization of the aqueous extract with standard volumetric…

1. Scope 1.1 This Standard provides the minimum criteria for the design, erection and use of single membrane, unreinforced or reinforced air-supported structures. 1.2 This Standard is intended only for single independent air- supported structures and those which are contiguous with other structures and are attached through a common element. 1.3 This Standard does not apply to…

This second edition cancels and replaces the first edition (i. e. ISO 2079:1973). Defines a nuber of generic terms for which the definition is considered necessary in order clarify the scope of these processes. In addition to terms used in the three official ISO languages (English, French and Russian), this International Standard includes the equivalent terms in the German language.

The designations of metals and alloys shall be based on the chemical composition limits given in International Standards. International chemical symbols shall be used for the designation of the principal metal and the major alloying elements followed by numbers indicating the metal grade or the nominal alloy content.

Specifies a method to determiine if a flammable material, when maintained at a selected equilibrium temperature and under the conditions of the test, gives off sufficient flammable vapour at this temperature to cause ignition on application of an external source of flame applied in a standard manner. The method is suitable for use over the temperature range 5 to 65 C.
