1. The following apparatus shall be used:

• (a) six sample containers made from plywood, three with inside dimensions of 900 mm long by 350 mm wide by 150 mm deep and three with inside dimensions of 450 mm long by 350 mm wide by 300 mm deep;

• (b) a depth gauge, as specified in section 5.2.2.2.1 of CSA A101, except with a pin that is at least 300 mm long; and

• (c) a blowing machine that has an adjustable air setting control and an agitator in its hopper and that is equipped with 30 m of 5 cm diameter corrugated blowing hose.

• 2. (1) Prepare a product labelled as suitable only for blowing application, or as suitable for blowing or pouring application, or that does not have a suitable method of application specified on its label in accordance with subsections (3), (4), (6) and (7).

• (2) Prepare a product labelled as suitable only for pouring application in accordance with subsections (3), (5), (6) and (7).

• (3) Determine the mass of the empty sample containers described in paragraph 1(a).

• (4) Determine the density of the product using the procedure set out in sections 7.4.3 and 7.4.5.1 of the Standard for Cellulose Insulation and subsections (6) and (7).

• (5) Determine the density of the product using the procedure set out in sections 7.4.4 and 7.4.5.1 of the Standard for Cellulose Insulation and subsections (6) and (7).

• (6) Measure the thickness of the insulation in the centre of the container and make four additional measurements at the centre of each quarter of the container and calculate the average thickness. Determine the mass of the specimen. Determine the design density using the following equation:

  Design Density = M_d/V_d × 1.27

  where: 

  M_d  is the mass of the specimen;

  where: 

  V_d  is the volume of the specimen calculated by internal length of container times internal width of container times average thickness of the insulation.

• (7) Calculate the average design density of the product, which is the average of results from all six containers obtained in the manner set out in subsection (6).

3. The apparatus specified in section 7.11.1 of the Standard for Cellulose Insulation shall be used.

• 4. (1) Determine the mass of a clean dry specimen holder (which mass is referred to in section 7.11.4.10 of the Standard for Cellulose Insulation as m_o).

• (2) Attach the sleeve to the specimen holder so as to fit snugly against the outer surface of the four sides of the holder using masking tape on the outer sleeve and specimen holder interface, so that the height of the holder and attached sleeve is 20 cm.

• 5. (1) Determine the mass of the product required to yield a specimen that is sufficient to fill the specimen holder to its top edge when the product is at its average design density as determined in subsection 2(7).

• (2) Pour the specimen evenly into the specimen holder.

• (3) If any portion of the specimen rests above the top edge of the specimen holder, prepare the specimen in accordance with subsection (6).

• (4) If the entire specimen rests below the top edge of the specimen holder, discard the specimen and repeat subsections (1) and (2).

• (5) If the top surface of the entire specimen rests flush with the top edge of the specimen holder, proceed to subsection (7).

• (6) Gently drop the specimen holder in such a manner that the base of the holder lands squarely on a hard surface and continue to drop the holder in this manner until the holder is filled flush to its top edge with the specimen.

• (7) Remove the sleeve and masking tape from the specimen holder.

6. Repeat the procedure set out in section 4 and in subsections 5(2) to (5) and (7) with two additional specimen holders.
