Laboratory glassware — Volumetric glassware — Methods for use and testing of capacity
The general procedure is based upon a determination of volume of water in the vessel. The described procedures are applicable to ware with capacities in the range of 0,1 to 2000 ml. These include transfer and one-mark pipettes without subdivision, graduated measuring pipettes and dilution pipettes, burettes and volumetric flasks. The apparatus, materials, accuracy, setting of the meniscus,…
Cross-country skis — Determination of mass and location of balance point
Specifies laboratory measurement methods for the characteristics mentioned above. If laboratory measurement data are determined and published by manufacturers, standard measurement procedures are recommended to ensure comparability.
Alpine skis — Determination of mass and polar moment of inertia — Laboratory measurement method
Specifies laboratory measuring methods for the characteristics mentioned above. If laboratory measurement data are determined by the manufacturer, standard measurement procedures are recommended to ensure compatibility. Specifies also a tolerance range which shall be met by the measurement data of all manufactured skis, if for the specific model length measurement data are published by the…
Air distribution and air diffusion — Laboratory aerodynamic testing and rating of air terminal devic...
Specifies laboratory aerodynamic testing and rating as well as test facilities and measurement techniques for air terminal devices. Gives only tests for the assessment of characteristics of the air terminal devices under isothermal conditions. A test method under non-isothermal conditions will be added when approved.
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…
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…
