Controlled equivalence ratio method for the determination of hazardous components of fire effluents - Steady-state tube furnace

ISO/TS 19700:2016 describes a steady-state tube furnace (SSTF) method for the generation of fire effluent for the identification and measurement of its constituent combustion products, in particular, the yields of toxicants under a range of fire decomposition conditions. It uses a moving test specimen and a tube furnace at different temperatures and airflow rates as the fire model. The interlaboratory reproducibility has been assessed with selected homogenous thermoplastic materials and this document is therefore limited in applicability to such materials. The method is validated for testing homogeneous thermoplastic materials that produce yields of a defined consistency. See limitations in Clause 12.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
