What is PD ISO/TR 16312-2 about?
PD ISO/TR 16312-2 assesses the utility of physical fire models that have been standardized, are commonly used, and/or are cited in national or international standards, for generating fire effluent toxicity data of known accuracy.
The aspects of the models that are considered are the intended application of the model, the combustion principles it manifests, the fire stage(s) that the model attempts to replicate, the types of data generated, the nature and appropriateness of the combustion conditions to which test specimens are exposed, and the degree of validity established for the model.
Who is PD ISO/TR 16312-2 for?
PD ISO/TR 16312-2 on assessing the validity of physical fire models is relevant to:
- Fire model manufacturers
- Designers
- Testers
- Any entity related to production and maintenance of fire models
Why should you use PD ISO/TR 16312-2?
The role of a physical fire model for generating accurate toxic effluent composition is to simulate the essential features of the complex thermal and reactive chemical environment in full-scale fires.
PD ISO/TR 16312-2 provides a set of technical criteria for evaluating physical fire models used to obtain composition and toxic potency data on the effluent from products and materials under fire conditions relevant to life safety. PD ISO/TR 16312-2 covers the application by experts of these criteria to currently used test methods that are used for generating data on smoke effluent from burning materials and commercial products. There are 10 physical fire models discussed in PD ISO/TR 16312-2.
What’s changed since the last update?
PD ISO/TR 16312-2 replaces the first edition (ISO/TR 16312‑2:2007) which has been technically revised. The main changes compared to the previous edition are as follows:
- Fire models have been updated following the publication of certain other standards, including ISO/TS 19021 and ISO/TS 5660‑5
- Deprecated methods have been moved to Annex A
