Interpretation

2 In these Regulations,

Act

Act means the Hazardous Products Act; (Loi)

laminated glass

laminated glass means two or more sheets of glass bonded to an intervening layer or layers of plastic material; (verre feuilleté)

safety glass standard

safety glass standard means Standard for Glass: Safety, for Building Construction, 12-GP-1b, August, 1971, a standard of the Canadian Government Specifications Board; (norme sur le verre de sécurité)

tempered glass

tempered glass means glass that has been treated chemically or thermally so that, upon fracture, an entire sheet or pane of the glass disintegrates into many small granular pieces; (verre trempé)

wired glass

wired glass means glass in which a wire mesh has been completely embedded. (verre armé)

General

3 For the purpose of item 17 of Part I of Schedule I to the Act, safety glass is

  • (a) laminated glass that, when subjected to the test referred to in Column I of each of items 1 to 4 of the table to this section, shows the resistance to boiling water and impact described in Column II of each such item;

  • (b) tempered glass that, when subjected to the test referred to in Column I of each of items 4 to 6 of the table to this section, shows the resistance to impact described in Column II of each such item; or

  • (c) wired glass that, when subjected to the test set out in Standard for Glass: Wired, Safety, for Building Construction, 12-GP-11, January, 1973, a standard of the Canadian Government Specifications Board, and referred to in Column I of item 7 of the table to this section, shows the resistance to impact described in Column II of that item.

Column IColumn II
TestResistance
1The test set out in paragraph 7.3.2 of the safety glass standardNo bubbles or other defects develop beyond 1/2 inch (12.7 mm) from the outer edge of the glass or from any crack that develops in the glass.
2The test set out in subparagraph 7.3.3.1 of the safety glass standard

  • (1) The ball does not go through the glass.

  • (2) If fragments of glass at the point immediately opposite the point of impact become detached, the exposed reinforcing or strengthening material is less than one square inch (645 mm2) in area and well covered with tiny particles of tightly adhering glass.

  • (3) The total area of separation of the glass from the reinforcing or strengthening material does not exceed three square inches (1 940 mm2) on each side.

  • (4) Spalling of the outer surface of the glass opposite the point of impact and in the area adjacent to such point may occur.

3The test set out in subparagraph 7.3.3.3 of the safety glass standardGlass may crack or lose its rigidity but no single fragment that becomes detached exceeds one gram in weight.
4The test set out in subparagraph 7.3.3.2 of the safety glass standardThe total weight of the 10 largest particles does not exceed the weight of 10 square inches (6 450 mm2) of the glass intact.
5The test set out in subparagraph 7.3.3.1 of the safety glass standardNo fracture occurs.
6The test set out in subparagraph 7.3.3.3 of the safety glass standardNo fracture occurs.
7The test set out in paragraph 7.3.2 of the standard described in paragraph 3(c)

  • (1) No fracture resulting in a shear or opening that would permit free passage of a sphere three inches (75 mm) in diameter occurs.

  • (2) The glass adjacent to each crack extending from the impact area is held in place by the reinforcing or strengthening material.

  • (3) While small fragments of glass from both sides of the specimen at or immediately around the point of impact become detached, no piece comes loose or detached from any other part of the glass.
