Eléments standard pour la construction des machines-outils — Consoles
La présente Norme Internationale fixe certaines dimensions relatives à l'interchangeabilité des consoles utilisées pour la construction des machines spéciales à l'aide d'éléments standard.
Steel products for pressure purposes — Derivation and verification of elevated temperature propertie...
Defines a method for deriving minimum elevated temperature proof stress values for inclusion in International Standards for austenitic steel products. Defines further a verification procedure which may be used by a manufacturer as an alternative to hot-testing for satisfying the purchaser that his product meets the specified minimum elevated temperature proof stress values.
Paints and varnishes — Determination of light fastness of paints for interior use
Specifies a method for operating laboratory equment. It does not attempt to define either the minimum accetable standard or the precise techniques to be adopted for the test; these are to be the subject of agreement between the interested parties. The posible forms which the test requirement may take are the following: The test material shall be at least as ligthfast as a specified wool scale…
Fluorochlorinated hydrocarbons for industrial use — Determination of acidity — Titrimetric method
Applicable to products the acidity of which is between 2 mol and 200 mol of univalent acid per kg. Two procedures are given: one is applicable to liquid products (R11, R113, etc.) and the other one to gaseous (R12, R22, etc.). The principle consists in extraction of the acids by water. Titration of the acids in the aqueous phase with standard volumetric sodium hydroxide solution in the presence…
Specifies the objective criteria which make it possible to assess the value of the results obtained in each particular case. It is not intended to prescribe a type of apparatus or a procedure for converting the instrument response to concentrations units because of the broad range of equipment available and the difficulty of completely specifying all working conditions in a spectrographic…
Zinc ingots — Selection and preparation of samples for spectrographic analysis
Sampling may be carried out either by drilling or by sawing slices. Both methods of sampling provide a sample for possible analyses by other standardized methods. ISO 3816 applies only to samples from zinc ingots. Alternatively, the interested parties may agree to select samples of zinc in the liquid state during production.
Zinc alloy ingots — Selection and preparation of samples for spectrographic analysis
Sampling may be carried out either by drilling or by sawing slices. Both methods of sampling provide a sample for possible analyses by other standardized methods. Applies only to samples from zinc alloy ingots. Alternatively, the interested parties may agree to select samples of zinc alloy in the liquid state during production.
The Standard specifies the following characteristics of the oil. Appearance: Clear, mobile liquid. Colour: Pale yellow to pale brownish yellow. Odour: Characteristic, recalling that of citronellal. Relative density at 20/20 °C: 0,880 - 0,895. Refractive index at 20 °C: 1,4660 - 1,4730. Optical rotation at 20 °C: Range from - 5 to 0 . Solubility in 80 % (V/V) ethanol at 20 °C: 1 volume in 2…
Sulphur for industrial use — Determination of acidity — Titrimetric method
Applicable to products having acidities, expressed as H2 SO4 , equal to or more than 0.01 % (m/m). Describes the extraction of acidic substances with a mixture of water and propan-2-ol (isopropyl alcohol). Titration of the extract with standard volumetric sodium hydroxide solution in the presence of phenolphthalein as indicator. The preparation of the sample from the laboratory sample is carried…
Application of Filled Cutback Asphalts for Dampproofing and Waterproofing
Scope
1.1 This standard describes the recommended procedures to be employed in applying filled cutback asphalts, covered by CGSB 37-GP-16M, in dampproofing or waterproofing footings, floors, walls and structural slabs.
