Plastics — Methyl methacrylate/acrylonitrile/butadiene/styrene (MABS) moulding and extrusion materia...
The types of MABS plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties Vicat softening temperature, melt flow rate, impact strength, flexural modulus and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing…
Radiotherapy simulators - Guidelines for functional performance characteristics
The guidelines given in this report are recommendations both to manufacturers and to users. They provide guidance to manufacturers about the needs of radiotherapists in respect to the performance of radiotherapy simulators and they provide guidance to users wishing to check the manufacturer's declared performance characteristics to carry out acceptance tests and to check periodically the…

Water quality — Sampling in deep waters for macro-invertebrates — Guidance on the use of colonizatio...
The colonization samplers described allow water quality to be assessed by providing a collection of macro-invertebrates indicative of the water quality at the sites of concern. They do not sample the natural invertebrate fauna, which may be restricted by physical conditions unrelated to water quality, and are to be used when studying lowland river waters of depth over 1 m. The deep water samplers…
Plastics — Ethylene/vinyl acetate (E/VAC) moulding and extrusion materials — Part 1: Designation and...
The types of E/VAC plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties vinyl acetate content and melt flow rate and on information about intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. Applies to all E/VAC copolymers containing from 3 % (m/m…

Information technology — Coding of moving pictures and associated audio for digital storage media at...
Specifies the coded representation of video for digital storage media and the decoding process. Is primarily applicable to digital storage media supporting a continuous transfer rate up to about 1,5 Mbit/s, such as compact disc, digital audio tape, and magnetic hard disc, and for non-interlaced video formats having approximately 288 lines of 352 pels and picture rates around 24 Hz to 30 Hz.…
Information technology — Coding of moving pictures and associated audio for digital storage media at...
Specifies the coded representation of high quality audio for storage media and the method for decoding of high quality audio signals. Is intended for application to digital storage media providing a total continuous transfer rate of about 1,5 Mbit/s for both audio and video bitstreams, such as CD, DAT and magnetic hard disc, and for sampling rates of 32 kHz, 44,1 kHz, and 48 kHz.
Information technology — Coding of moving pictures and associated audio for digital storage media at...
Specifies the system layer of the coding. Was developed principally to support the combination of the video and audio coding methods defined in ISO/IEC 11172-2 and ISO/IEC 11172-3. The system layer supports the following basic functions: the synchronization of multiple compressed streams on playback, the interleaving of multiple compressed streams into a single stream, the initializiation of…
