Cellular plastics — Determination of tensile properties of rigid materials
Applies primarily to ceelular materials having a sufficient compression resistance to permit suitable gripping of the test pieces. The test piece of a given shape is subjected to a tensile stress, transmitted to the test piece by means of a suitable device. The corresponding stress-strain curve shall be recorded. In the case of low compression resistance the bonding of reinforcing metall plates…
Glass alcoholometers and alcohol hydrometers not incorporating a thermometer
Three different types of glass instruments for the accurate determination of the ethanol content of simple mixtures of ethanol and water are specified: alcoholometers graduated in percentage of ethanol by volume or by mass and alcohol hydrometers graduated in units of density. Construction, material and scale are described. The dimensions are tabled and the value of the ethanol content by mass or…
Anionic and non-ionic surface active agents — Determination of the critical micellization concentrat...
The method is carried out in the following way: Determination of the surface tension of a series of solutions whose concentrations bracket the critical micellization concentration. Plotting of the graph of surface tension as a function of the logarithm of the concentration: the critical micellization concentration corresponds to a singular point on this curve. In this point the curve shows a…
Tolerances for building — Part 1: Basic principles for evaluation and specification
Describes the nature of dimensional variability in building and the purposes for which it has to be quantified, and defines the factors to be taken into account in the evaluation, specification and verification of tolerances for the manufacture of building components and for site work. Applies to components and buildings generally, including those designed in accordance with the principles of…
Documentation — Abstract sheets in serial publications
Sets out rules for the presentation of an abstract sheet in a periodical or other serial publication. Such abstract sheet provides a detailed description of each article, giving such details as are essential for documentation work. Covers definition, text of abstract sheet, physical presentation, language(s) of abstract sheet and an example of an abstract sheet in English.
Shipbuilding — Inland navigation — Sealing rubber for covers of cargo hatches
Specifies the type, principal dimensions and technical requirements. Does not apply to special rubber packings intended to create heat-insulating labyrinths.
