  • (b) the hardness of the wash water must be less than 50 ppm of calcium carbonate;

  • (c) for automatic washing machines, the washing cycle must be set for normal washing cycle;

  • (d) a synthetic detergent that conforms to CGSB standard 2-GP-115M, Standard for Detergent, Laundry, Powder, Built, dated January 1979, must be used; and

  • (e) a bleaching agent containing sodium hypochlorite that produces 0.015% of available chlorine when it is added to the washing solution must be used.

Drying Procedure

• 4 The apparatus and drying procedure set out in sections 4.2 and 7.5, respectively, of Method 58, the National Standard of Canada CAN2-4.2-M77, Colour Fastness and Dimensional Change in Domestic Laundering of Textiles, published by CGSB in December 1984, must be used.

Specimen Preparation and Testing

• • 5 (1) Four specimens measuring 89 mm × 254 mm must be cut from the loose-fitting sleepwear that has been washed and dried or dry cleaned in accordance with sections 1 to 4, in such a manner that two specimens are cut in the lengthwise direction and two are cut in the crosswise direction of the sleepwear. The specimens cut from sleepwear made from a multilayered fabric must include all layers of the fabric and must be held in the relative positions they occupy. The direction in which each specimen was cut must be indicated on the specimen.

  • (2) The four specimens must be tested in accordance with the procedures set out in paragraphs 1616.5(a) and (b) and subparagraphs 1616.5(c)(1) to (3) of Standard FF 5-74 of the United States Consumer Product Safety Commission, Standard for the Flammability of Children’s Sleepwear: Sizes 7 through 14, published January 1, 1985 in the Code of Federal Regulations, Part 1000 to end.

  • (3) The average char lengths for the two specimens cut in the lengthwise direction and for the two specimens cut in the crosswise direction must be determined.

  • (4) A fifth specimen must be cut in the same direction as the specimens having the longer average char length and tested in accordance with the procedures referred to in subsection (2).

  • (5) The char length, the direction in which each of the five specimens tested was cut and the average char length of the five specimens must be recorded.
