CAN/CGSB-4.2 No. 27.4-94

This National Standard of Canada is equivalent to International Standard ISO 6940:1984. 1 Scope and field of application This International Standard specifies a method for the measurement of ease of ignition 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. This method should be used solely to assess the properties of materials or systems in response to heat and flame under controlled conditions. Results may not apply to situations where there is restricted air supply or prolonged exposure to large sources of intense heat as in a conflagration.
