Reaction-to-fire tests -- Heat release, smoke production and mass loss rate -- Part 3: Guidance on measurement
Это стандарт пересмотрен ISO/TS 5660-3:2012
ISO/TR 5660-3:2003 examines the limitations of the cone calorimeter as currently used for building products and recommends ways in which some of these may be overcome for other types of products for other application areas. It compiles information from a large body of experience with regard to the use of the instrument into a set of guidelines which will help to standardize the use of the cone calorimeter in this wider scope.
Particular guidance is given on aspects of specimen preparation and on the behaviour, such as melting, spalling and intumescing, of specimens exposed to radiant heat. The relevance of specimen thickness and the use of substrate, and methods of fixing to substrate, are also discussed. Advice is given on approaches to testing a variety of "non standard" products. Recommendations are made on techniques of calibration of the apparatus, selection of appropriate heat flux levels and ignition protocols.
In addition to the guidance given to operators, ISO/TR 5660-3:2003 makes recommendations on presentation of the test results.
