Plastics - Reaction to fire - Test method for flame spread and combustion product release from vertically oriented specimens

ISO 21367:2007 specifies a test method for plastics for the determination of the heat release rate, ignitability, surface spread of a flame, falling droplets/particles and smoke production using a "medium" scale specimen that simulates the early development stage of the fire. This test method can be used as a screening test for intermediate scale and large scale tests in addition to its use in factory production control, research and product development.ISO 21367:2007 provides data that is suitable for comparing reaction-to-fire performance of many materials, products, composites or assemblies under end use application conditions.The results of this test method are limited to specimens with heat release rates of less than 10 kW.

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.
