  1. Hazardous Products Regulations - SOR/2015-17 (Section 1)
    Marginal note:Definitions
    •  (1) The following definitions apply in these Regulations.

      flash point

      flash point  means the lowest temperature, corrected to the standard pressure of 101.3 kPa, at which the application of an ignition source causes the vapours of a liquid to ignite. (point d’éclair)

      initial boiling point

      initial boiling point  means the temperature of a liquid at which its vapour pressure is equal to the standard pressure of 101.3 kPa, i.e., the temperature at which the first gas bubble appears. (point d’ébullition initial)

      SADT

      SADT or self-accelerating decomposition temperature means the lowest temperature at which self-accelerating decomposition occurs. (TDAA ou température de décomposition autoaccélérée)


  2. Hazardous Products Regulations - SOR/2015-17 (Section 7.12.1)
    Marginal note:Exclusions
    • [...]

    • (2) A liquid or solid which, in contact with water, emits flammable gases is classified in a category of this hazard class, based on results from testing performed in accordance with test N.5 of sub-section 33.4.1.4 of Part III of the Manual of Tests and Criteria, in accordance with the following table:

      TABLE

      Column 1 Column 2
      Item Category Criteria
      1 Substances and Mixtures Which, in Contact with Water, Emit Flammable Gases — Category 1

      A liquid or solid that

      • (a) reacts with water at ambient temperature and produces a gas that is liable to ignite spontaneously;

      • (b) reacts with water at ambient temperature such that the rate of evolution of flammable gas is ≥ 10 l/kg of liquid or solid over any one minute; or

      • (c) reacts with water at ambient temperature to ignite spontaneously in any step of the test procedure

      2 Substances and Mixtures Which, in Contact with Water, Emit Flammable Gases — Category 2 A liquid or solid that reacts with water at ambient temperature such that the maximum rate of evolution of flammable gas is ≥ 20 l/kg of liquid or solid per hour
      3 Substances and Mixtures Which, in Contact with Water, Emit Flammable Gases — Category 3 A liquid or solid that reacts with water at ambient temperature such that the maximum rate of evolution of flammable gas is ≥ 1 l/kg of liquid or solid per hour

  3. Hazardous Products Regulations - SOR/2015-17 (Section 7.11.1)
    Marginal note:Exclusions
    • [...]

    • (2) Subject to subsection (3), a self-heating substance or mixture is classified in a category of this hazard class, based on results from testing performed in accordance with test N.4 of sub-section 33.3.1.6 of Part III of the Manual of Tests and Criteria, in accordance with the following table:

      TABLE

      Column 1 Column 2
      Item Category Criteria
      1 Self-heating Substances and Mixtures — Category 1 A solid or liquid in respect of which a positive result is obtained in a test using a 25 mm sample cube at 140°C and the spontaneous ignition temperature of a 450 l volume of the solid or liquid is ≤ 50°C
      2 Self-heating Substances and Mixtures — Category 2

      A solid or liquid in respect of which

      • [...]

      • (b) a positive result is obtained in a test using a 25 mm sample cube at 140°C and the spontaneous ignition temperature of a 450 l volume of the solid or liquid is > 50°C

    • Marginal note:Exclusion after evaluation

      (3) A mixture or substance with a temperature of spontaneous combustion higher than 50°C for a volume of 27 m3 need not be classified in any category of this hazard class.


  4. Hazardous Products Regulations - SOR/2015-17 (Section 7.5.1)

     A gas under pressure is classified in a category of this hazard class in accordance with the following table:

    TABLE

    Column 1 Column 2
    Item Category Criteria
    1 Gases Under Pressure — Compressed Gas A gas that when packaged under pressure is entirely gaseous at -50°C, including all gases with a critical temperature ≤ -50°C
    2 Gases Under Pressure — Liquefied Gas A gas that when packaged under pressure is partially liquid at temperatures > -50°C
    3 Gases Under Pressure — Refrigerated Liquefied Gas A gas that when packaged is partially liquid because of its low temperature

  5. Hazardous Products Regulations - SOR/2015-17 (Section 7.5)

     The following definitions apply in this Subpart.

    critical temperature

    critical temperature means the temperature above which a pure gas cannot be liquefied, regardless of the degree of compression. (température critique)
