Once this has been established, the flammability of the product sample is determined by measuring the flame Flammability of Textile Products in Canada 7 spread time for five test specimens from the same sample and averaging the results. [...] The flame spread time of the product sample is then the average flame spread time for the ten specimens or for the number of specimens that burned. [...] The more loosely woven a fabric, the more combustible it is, and the faster the flame will travel over the surface of the fabric. [...] Children’s Sleepwear or Bedding • ensure that the fabric being used meets the basic HPA flammability requirements for general textile products •. if the fabric is used to manufacture children’s sleepwear, ensure that it meets the more stringent HPA flammability requirements which are applicable to the style of children’s sleepwear they are producing •. if the fabric is used to manufacture bedding,
