Annex C (informative) Guidance on system application environment

Rubber and plastics hoses. Method of test for flammability Ingestion-build-105964 and air conditioning (HVAC) ducts1 Scope This International Standard specifies a method for assessing the flammability of hoses, except for hoses intended for use with petroleum fuels for combustion engines. The method is restricted to hoses of sizes up to and including nominal bore of 50 mm. NOTE 1 The user is referred to the applicable hose standard for flame afterglow requirements. NOTE 2 The method of test for flammability of hoses for use with petroleum fuels is given in ISO
