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

Drying Procedure

• 4 The apparatus and drying procedure set out respectively in sections 4.2 and 7.5 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, shall be used.

Specimen Preparation and Testing

• • 5 (1) Four specimens measuring 89 mm × 254 mm shall be cut from a sample of the product 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 product. The specimens cut from a product made from a multilayered fabric shall include all layers of the fabric and shall be held in the relative positions they occupy. The direction in which each specimen was cut shall be indicated on the specimen.

  • (2) The four specimens shall 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 FF5-74 of the United States Consumer Product Safety Commission, Standard for the Flammability of Children’s Sleepwear: Sizes 7 through 14, dated January 1, 1985 and published 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 shall be determined.

  • (4) A fifth specimen shall be cut in the same direction as the specimens having the longer average char length, as determined pursuant to subsection (3), and this fifth specimen shall be 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 shall be recorded.
