This International Standard covers the following aspects of fire testing: — selection of appropriate test(s); — listing of reaction-to-fire characteristics which the test(s) can measure; — assessment of the test(s) for their suitability for material characterization, quality control, pre-selection and/or end-product testing; — problems that can arise when plastics specimens are tested in standard fire tests. Particular attention is given to the provision of guidance for inexperienced users who may need to assess the fire performance of materials or products made of, or incorporating, plastics. This International Standard also provides answers to frequently asked questions concerning standard fire tests; these cover factors such as cost, test duration, complexity, required operator skills, quality of the data produced, relevance to fire hazard assessment as well as test repeatability and reproducibility. Preparation of this International Standard has involved a review and assessment of the most frequently used fire tests applied to the materials and products within the scope of ISO/TC 61/SC 4. The main focus in this International Standard is on reaction-to-fire testing. Fire-resistance testing has also been considered, however, in order to take account of the widespread use of advanced polymer composites and related materials with superior thermo-mechanical stability which may be used in applications where there is a demand for some degree of fire resistance. Further development of such plastics composites and related products will predictably increase the demand for fire-resistance testing. The scope of this International Standard does not include the development or design of fire tests for plastics.

Is applicable to end systems concerned with operating in the Open Systems Interconnection environment. It specifies a combination of OSI standards, which collectively provide the connection-mode Transport Service using the connection-mode Network Service. Is applicable to the provision of the connection-mode Transport Service in end systems attached to any type of subnetwork from which the standardized connection-mode Network Service can be made available. Specifies the specific requirements for the TB group.

This International Standard — defines smoking parameters and specifies the standard conditions to be provided for the routine analytical machine smoking of cigarettes; — specifies the requirements for a routine analytical smoking machine complying with the standard conditions. Annex A specifies the ambient air velocities surrounding cigarettes in a routine analytical smoking machine, the mechanical design of the enclosures immediately surrounding them, and the methods of air velocity measurement including the location where air velocity is measured. Annex B describes, as an example, the special characteristics of a typical smoking machine incorporating a piston type of puffing mechanism. Annex C includes a diagram of a puff profile and illustrates definitions and standard conditions.
