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…
Laboratory glassware — Graduated pipettes — Part 4: Blow-out pipettes
The special requirements concern the capacity, graduation, figuring, delivery and identification. The lower end of the scale and the delivery time are tabled for the nominal capacity. The handling of the pipettes at the measurement is specified.
Plastics laboratory ware — Graduated measuring cylinders
The requirements specify a series of plastic cylinders having a graduated volumetric scale and a pouring spout. The series of nominal capacities is tabled and so do the dimesions. The construction is illustrated by some figures showing the general appearance and the scales of measuring cylinders. The annex deal with testing of plastic cylinders, test for ionic material extracted by water and with…
The specified requirements deal with two series of inexpensive "commercial" liquid-in-glass thermometers, when great accuracy of measurement is not requirend: a series designated A to H, in which nominal ranges and maximum overall lengths are specified and a series designated J to W of greater accuracy and with specifies ranges and overall length, which may be acceptable for testing by…
Methods of measurement of the suppression characteristics of passive radio interference filters and ...
Prescribes methods of measurement of insertion loss of passive radio
frequency suppression filters, which may consist of single
elements, such as capacitors, inductors or resistors, or
combinations of inductors, capacitors and resistors of either the
lumped or distributed types. The methods include those for use in a
laboratory or on a production line, utilizing fixed impedance
terminations or…
Road vehicles — Brake linings — Resistance to water, saline solution, oil and brake fluid — Test pro...
Specifies a laboratory method for exposing samples to detrimental environments, measuring the effect on strength and shape and comparing the results with those from uncontaminated samples. Applies to drum brake linings and disc brake pads being of organic content and intended for service on road vehicles.
