Safety and performance criteria for seamless gas cylinders
Offers guidance towards the preparation of future gas cylinder standards, revisions to existing gas cylinder standards, and identifies aspects of design criteria and tests which are recognized as providing information relevant to the safety and performance in service of seamless gas cylinders of water capacities between 0,5 l and 150 l. These principles shall also be applied, where possible, to…
Plastics — Thermoplastic materials — Determination of Vicat softening temperature (VST)
Specifies four methods for the determination: method A50 using a force of 10 N and a heating rate of 50 °C/h, method B50 using a force of 50 N and a heating rate of 50 °C/h, method A120 using a force of 10 N and a heating rate of 120 °C/h, method B120 using a force of 50 N and a heating rate of 120 °C/h. The principle is determining the temperature at which a standard indenter penetrates 1 mm…

Provides developers of OSI recommendations/international standards that contain managed object definitions with generic definitions of managed object classes which may be used as superclasses, using the template notation defined in CCITT Rec. X.722 / ISO/IEC 10165-4, including the definition of any packages, attributes, attribute groups, behaviour, actions, notifications and parameters that may…
Ceramic pressurized hollow insulators for high-voltage switchgear and controlgear
Applies to hollow insulators made of ceramic material, with their fixing devices, intended for use with a permanent gas pressure greater than 50 kPa gauge having an internal volume equal to or greater than 1 litre (1000 cm3). They are intended for use in electrical equipment operating on alternating current with a rated voltage greater than 1000 V and a frequency not greater than 100 Hz or for…
Medical electrical equipment - Part 1: General requirements for safety - 3. Collateral standard: Gen...
Establishes general requirements for protection against ionizing radiation in medical diagnostic X-ray equipment, in order that the dose equivalent to the patient, the operator and other staff can be kept as low as reasonably achievable.
Medical electrical equipment - Characteristics of electro-optical X-ray image intensifiers - Part 2:...
Applies to electro-optical X-ray image intensifiers for medical use, as components of diagnostic X-ray equipment. Describes a method of determining the conversion factor of X-ray image intensifiers.This standard is applicable only to devices whose output light spectra do not significantly deviate from that of a P-20 phosphor.
Replaces IEC 60573.
