This standard specifies safety requirements for construction and performance requirements of welding power sources

Determination

does not apply to the operation and maintenance phase of the E/E/PE safety-related systems – this is dealt with in IEC 61508-1 – however

Rules for rounding

The tests described in this standard require the quality and performance of the X-ray image receptors to be assured prior to the acceptance testing when they are not an integral part of the mammographic X-ray equipment

Procedure for the comparison of noise emission data for machinery and equipment BS EN ISO 11689 specifies a method for establishing the noise control performance of machinery or equipment on the basis of noise emission data. It applies to any kind of machinery or equipment for which a noise test code exists or comparable noise emmission data is available. The general procedure specified in BS EN ISO 11689 can also be
