ISO/IEC 21991:2002 specifies signalling interworking between "QSIG" and "H.323" in support of call completion supplementary services within a Corporate telecommunication Network (CN). "QSIG" is a signalling protocol that operates at the Q reference point between Private Integrated services Network eXchanges (PINX) within a Private Integrated Services Network (PISN).…

ISO/TR 16982:2002 provides information on human-centred usability methods which can be used for design and evaluation. It details the advantages, disadvantages and other factors relevant to using each usability method. It explains the implications of the stage of the life cycle and the individual project characteristics for the selection of usability methods and provides examples of usability…

Gives the requirements for sleeving constructed from polyethylene terephthalate yarn, lightly impregnated with resin to provide mechanical stability. This sleeving has been found suitable for use at temperatures up to 130 °C. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be…

Gives the requirements for glass textile fibre sleeving, uncoated, constructed from a braid of E-type yarn. The sleeving is annealed by heat treatment to assist in maintaining a circular cross-section. This sleeving is suitable for use at temperatures up to 350 °C. It is normally available in internal diameters between 0,5 mm and 30 mm and is normally supplied in its natural colour. Materials…

Gives the requirements for heat-shrinkable (low and high shrink ratio) polytetrafluorethylene (PTFE) sleeving. It is normally available in expanded internal diameter sizes up to 12 mm in three wall thickness ranges as supplied in the low shrink ratio (sheets 240, 241 and 242) and up to 100 mm in one wall thickness range as supplied in the high shrink ratio (sheet 243). It is normally available in…

Gives the requirements for sleeving having the property of expanding its internal diameter when compressed longitudinally and thereafter returning to its initial diameter after release of the compressing force. This expandable braided textile sleeving, uncoated, is constructed of ethylene chlorotrifluoroethylene (E-CTFE) monofilament yarns suitably processed to provide the mechanical ability to…

Gives the requirements for three types of E-type glass sleeving using either braided or knitted construction, with a continuous silicone elastomer coating and differentiated by their breakdown voltage (sheet 400: high breakdown voltage; sheet 401: medium breakdown voltage; sheet 402: low breakdown voltage). These sleevings have been found suitable for temperatures up to 180 °C. Materials which…

This International Standard specifies the physical, mechanical, packaging and labelling requirements for curing polymerizing radio-opaque and non-radio-opaque resin cements based on poly(methacrylic acid esters). It applies to two types of cement, intended respectively for use with a syringe or in the dough state, for the fixation of internal orthopaedic prostheses and supplied as units…
