Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
IEC 60079-17:2013 applies to users and covers factors directly related to the inspection and maintenance of electrical installations within hazardous areas only, where the hazard may be caused by flammable gases, vapours, mists, dusts, fibres or flyings. It does not include:
- other fundamental installation and inspection requirements for electrical installations;
- the verification of electrical…
Ultrasonics - Power measurement - High intensity therapeutic ultrasound (HITU) transducers and syste...
IEC 62555:2013 establishes general principles relevant to HITU fields for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; specifies a calorimetric method of determining the total emitted acoustic power of ultrasonic transducers based on the measurement of thermal expansion of a fluid-filled target; specifies requirements related to the…
Superconductivity - Part 19: Mechanical properties measurement - Room temperature tensile test of re...
IEC 61788-19:2013 covers a test method detailing the tensile test procedures to be carried out on reacted Cu/Nb3Sn composite superconducting wires at room temperature. The object of this test is to measure the modulus of elasticity and to determine the proof strength of the composite due to yielding of the copper and the copper tin components from the stress versus strain curve. Furthermore, the…
Cereals and pulses — Determination of the nitrogen content and calculation of the crude protein cont...
ISO 20483:2013 specifies a method for the determination of the nitrogen content of cereals, pulses and derived products, according to the Kjeldahl method, and a method for calculating the crude protein content. The method does not distinguish between protein nitrogen and non-protein nitrogen.
Vehicle security barriers — Part 1: Performance requirement, vehicle impact test method and performa...
IWA 14-1:2013 specifies the essential impact performance requirement for a vehicle security barrier (VSB) and a test method for rating its performance when subjected to a single impact by a test vehicle not driven by a human being.
