Standards
This document specifies a method for the magnetic particle testing of ferro-magnetic steel and iron castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. This document is applicable to all ferro-magnetic castings, independent of the moulding method. A steel and iron casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T
(Tesla) for a magnetic field strength of 2,4 kA/m. This document only applies to those areas of the castings specified for testing, as well as the percentage
of castings to be tested
This document specifies a method for the liquid penetrant testing of steel and iron castings.
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.
This standard specifies requirements and dimensions for PVC insulated cables for operation at nominal voltages up to and including 1900 V to armour or earth and 3300 V between conductors.
This standard covers thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80 C (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.
This standard describes the requirements and operational parameters for electrical appliance protectors for use with equipment at normal voltage of 110V, 120V,220V, 240V and a current of up to including 40 A.
