Photography — Expendable photoflash lamps — Definition and evaluation of flashability
The specifications are applicable to photoflash lamps in which the light is produced by an electrically initiated combustion within a transparent envelope. The "flashability" of an expendable photoflash lamp is defined, and standard methods for its evaluation and performance requirements are described.
1. Scope
1.1 This Standard covers hexagon and squate galvanized steel tower bolts and
nuts, in three grades corresponding to SAE Grade 2, SAE Grade 5, and SAE Grade
5.2 and ranging in size from ½ to 1 inch in diameter inclusive.
1.2 These bolts are intended for use in metal structures for electrical power
transmission and substations, metal antenna towers and similar structures.

This is a text searchable PDF.
1.1 Scope
1.1.1 These requirements apply to natural and propane gas-fired conversion burners designed and constructed primarily for the purpose of converting heating and process equipment from the use of other fuels to gas firing and/or firing new heating or process equipment.
1.1.2 Section 2, Part A of these requirements apply to conversion…
Éléments standard pour la construction des machines-outils — Bâtis latéraux pour tables de déplaceme...
La présente Norme Internationale fixe certaines dimensions, relatives à l'interchangeabilité, des bâtis latéraux pour tables de déplacement rectiligne utilisés pour la construction des machines spéciales à l'aide d'éléments modulaires.
Potassium sulphate for industrial use — Determination of acidity to methyl orange
The principle of the analysis consists in dissolution of the test solution in water and titration of the acidity, in presence of methyl orange, using standard volumetric sodium hydroxide solution. If the solution is coloured yellow the product is not acid with respect to methyl orange.
Ammonium hydrogen carbonate for industrial use (including foodstuffs) — Determination of ammoniacal ...
Specifies a titrimetric method consisting in distillation of the ammonia after displacement by an alkaline solution; absorption in an excess of standard volumetric sulphuric acid solution and back-titration with standard volumetric sodium hydroxide solution in the presence of an indicator. The absorption of the ammonia may also be carried out in an excess of boric acid solution. The titration, in…
Ammonium hydrogen carbonate for industrial use (including foodstuffs) — Determination of total alkal...
The principle of the analysis consists in acidification of a test solution by addition of an excess of standard volumetric sulphuric acid solution and back-titration with standard volumetric sodium hydroxide solution in the presence of methyl red- methylene blue mixed indicator.
Potassium hydroxide for industrial use — Method of assay
Method for determination of the titre, conventionally expressed as percentages by mass of KOH. There are three ways: a) total alkalinity, b) caustic alkalinity corresponding to the total alkalinity less the alkalinity due to carbonates and c) actual potassium hydroxide corresponding to the total alkalinity less the alkalinity due to carbonates and any hydroxide which may be present. The principle…
Heat-resisting equipment wires for aircraft — Methods of test
This International Standard specifies the rest procedures suitable for establishing the compliance of wires with the performance requirements stated in ISO 2032. They are intended for use as a basis for specifying tests in the relevant national specifications when the national type approving authorities consider that existing tests are inadequate. The test procedures are classified in type tests…
