Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
The test may be carried out on products as received or on a dried sample. The method specified in ISO 2208 shall be applied for drying. The principle of the method consists in cooling the liquid or liquefied test portion and observation of the temperature during crystallization under defined conditions. A simplified crystallization point apparatus is given in the figure. It takes into account the…
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
The method is applicable to products having high cresol contents. The principle consists in distillation of a test portion inder carefully defined conditions. Either determination of the temperatures corresponding to the condensate volumes defined or determination of the volume condensate when the thermometer indicates each of the distillaton temperatures (i.e. plotting temperature as a function…
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
Applicable to products having a high o-cresol content and a high m-cresol content. The principle consists in distillation of a tast portion under carefully defined conditions and determination of the mass of residue obtained. The distillation is carried out according to ISO 918. When all the water has distilled over, continue the distillation without intermediate measurements, until either the…
Road vehicles — Measurement methods for gaseous pollutants emitted by mopeds equipped with a control...
Specifies methods of measurement for gaseous pollutants emitted by mopeds as defined in ISO 3833, equipped with a 4-stroke, a 2-stroke or a rotary controlled ignition engine. Defines a driving cycle in accordance with the requirements of different types of mopeds and provides specifications of the collecting methods for gaseous pollutants, a measuring system and a test bench. This second edition…
Refractory materials — Determination of true density
Establishes a method for measuring the true density of refractory products and raw materials. It is defined as the ratio of the mass of a quantity of dried material to its true volume and is calculated from the expression is the density of the liquid used at the temperature of the thermostatically controlled bath, and m1, m2, m3 are the masses determined in accordance with clause 7.
Lays down a set of check characters systems capable of protecting strings against errors occurring when copying or entering data. Defines conformance requirements for products described as generating check characters or checking strings.
Lays down a set of check characters systems capable of protecting strings against errors occurring when copying or entering data. Defines conformance requirements for products described as generating check characters or checking strings.
Defines the type H and type Z; dimensions are illustrated by figures; tabulates gauge dimensions from No. 0 up to and including No. 4; includes a method of penetration gauging for both types.
Nuclear power plants — Guidelines to ensure quality of collected data on reliability
The output of a data collection system is strongly dependent on the quality of the information collected. Before starting such a system, it is necessary to clearly define the following items: the overall goal, the suppliers of field data, the users of processed data, the terms and expressions used, the means used to collect data and to treat them, the questions to be answered by field data, field…
Defines only the requirements and characteristics of test benches. Applies to test benches suitable for calibration of fuel injection equipment for compression ignition engines requiring fuel delivery up to 300 mm^3/injection/cylinder at full load. Some figures show diagrams as well as a test record sheet (figure 7), an analysis sheet (figure 8), and a field test sheet (figure 9).
