CAN/CGSB-4.2 No. 27.3-94

This National Standard of Canada is equivalent to International Standard ISO 6941:1984. 1 Scope and field of application This International Standard specifies a method for the measurement of flame spread properties of vertically oriented textile fabrics intended for apparel, curtains and draperies in the form of single- or multi-component (coated, quilted, multilayered, sandwich construction and similar combinations) fabrics. The method should be used solely to assess the properties of materials or systems in response to heat flame under controlled laboratory conditions. The results may not apply to situations where there is restricted air supply or prolonged exposure to heat as in a conflagration.
