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.
