Long-term leach testing of solidified radioactive waste forms
Provided to measure the resistance to leaching of the solidified materials: glass, glass-ceramics, ceramics, bitumen, cement, concrete, plastics, the test being aimed at the comparison of different kinds or compositions, intercomparison between test results from different laboratories on one product or on products of different processes. It is not required to carry out tests in all possible…
Environmental tests for aircraft equipment — Part 3.4 : Acoustic vibration
Specifies laboratory conditions for testing the ability of equipment for subsonic and supersonic civil aircraft to withstand vibration. Two types of tests are specified: tests for the functioning of the equipment and tests for its acoustic endurance. The necessity of such tests, the use of the wide band noise method or harmonic sound method, and the applicable test sound pressure level shall be…
Laboratory glassware — Methods for assessing the chemical resistance of enamels used for colour codi...
Test methods for determining the service performance of enamels are specified, i.e. for determining whether an enamel resists the specified treatment. The procedure insolve treatment for specified periods with an alkine detergent at 80 degrees centigrade and a dilute acid solution at room temperature.
The rules and conventions established are intended for particular use with drawings for laboratory glassware or glassware in other technical fields. Optical parts are not included. The figures merely illustrate the text and should not be considered design examples. They are simplified and not to ecale.
Specifies a test method for passenger cars, which permits the direct comparison of results obtained in different test laboratories. Two figures illustrate shapes and reference quantities of concern. This second edition cancels and replaces the first edition (1977).
Hydraulic fluid power — Filters — Evaluation of pressure drop versus flow characteristics
Specifies the method of measuring the pressure drop across a fluid filter under various conditions of flow. Two standards of measurement are specified: class A - for accurate evaluation for referee purposes - requiring laboratory conditions; class B - for evaluation for general purposes - requiring test facilities less stringent that laboratory conditions. Figure 1 shows an example for a suitable…
Plastics — Measurement of resistivity of conductive plastics
Specifies the requirements for the laboratory testing of the resistivity of specially prepared specimens of plastics made conductive by the incorporation of carbon black. The test is suitable for materials having a resistivity of less than 104 Ohm x m. A stable d.c. current is passed between electrodes at the ends of a test piece. A schematic diagram of the test circuit is given. The voltage drop…
