Standards
This standard specifies general rules for appropriate implementation of radiographic inspection and stresses the technical specifications to be defined for agreement on discontinuity acceptance criteria by this technique. It applies to aluminum castings.
This standard specifies a method for liquid penetrant inspection of discontinuities rising to the surface of aluminium alloy and magnesium alloy products and castings. It also defines severity levels as a function of the nature and number of discontinuities present. This standard applies to all aluminium alloy and magnesium alloy castings, whatever their grade and the casting procedure used to produce them.
This standard gives recommendations on the serviceability of buildings against vibrations. It covers three recipients of vibrations: a) human occupancy in buildings and on pedestrian bridges; b) the contents of the building; c) the structure of the building. It applies to buildings, pedestrian bridges and walkways found within buildings or connecting them and does not include bridges that carry vehicular traffic, nor the design of foundations or supporting structures of machinery.
This standard specifies requirements for the operation of testing and/or calibration laboratories. It is applicable to all laboratories regardless of the number of personnel or the extent of the scope of testing activities.
This standard specifies requirements for dusting powder prepared from a blend of materials to produce the characteristics set out in clause 2. It does not apply to aerosols.
This standard specifies
attachment fused and unfused plugs (caps), shuttered receptacles (sockets) for
flush surface mounting. These plugs and sockets are suitable for alternating
current circuits only of voltages not exceeding 250 volts and currents not
exceeding 15 amperes. The plugs and
receptacles covered by this standard are intended for use in making readily detachable
electrical connections in non-hazardous locations between supply circuits and
portable lamps, appliances and similar equipment.
This standard specifies requirements for bread and rolls and methods of test for these requirements.
The requirements cover television equipment intended for household and commercial use on supply circuits in accordance with the National Electrical Code, NFPA 70.
This standards covers thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80C (176 F) and lower temperatures on joints and splices in wires and cables in accordance with the National Electrical Code. It is intended that rubber tape on a joint or splice be mechanically protected by a covering such as friction tape . Thermoplastic tape is acceptable without the additional mechanical protection.
