• 7.14.1 (1) The following solids need not be classified in any category of this hazard class:

  • (a) any organic solid that does not contain oxygen, fluorine or chlorine;

  • (b) any organic solid that contains oxygen, fluorine or chlorine if those elements are chemically bonded only to carbon or hydrogen; and

  • (c) any inorganic solid that does not contain oxygen or halogens.

• Marginal note:Categories

  (2) An oxidizing solid is classified in a category of this hazard class, based on results from testing performed in accordance with test O.1 of sub-section 34.4.1 of Part III of the Manual of Tests and Criteria or test O.3 of sub-section 34.4.3 of that Part, in accordance with the following table:

  	Column 1	Column 2	Column 3
  Item	Category	Criteria Using Test O.1	Criteria Using Test O.3
  1	Oxidizing Solids — Category 1	A solid that, when tested in a 4:1 or 1:1 mixture, by mass, with cellulose, exhibits a mean burning time < the mean burning time of a 3:2 mixture, by mass, of potassium bromate and cellulose	A solid that, when tested in a 4:1 or 1:1 mixture, by mass, with cellulose, exhibits a mean burning rate > the mean burning rate of a 3:1 mixture, by mass, of calcium peroxide and cellulose
  2	Oxidizing Solids — Category 2	A solid that, when tested in a 4:1 or 1:1 mixture, by mass, with cellulose, exhibits a mean burning time ≤ the mean burning time of a 2:3 mixture, by mass, of potassium bromate and cellulose	A solid that, when tested in a 4:1 or 1:1 mixture, by mass, with cellulose, exhibits a mean burning rate ≥ the mean burning rate of a 1:1 mixture, by mass, of calcium peroxide and cellulose
  3	Oxidizing Solids — Category 3	A solid that, when tested in a 4:1 or 1:1 mixture, by mass, with cellulose, exhibits a mean burning time ≤ the mean burning time of a 3:7 mixture, by mass, of potassium bromate and cellulose	A solid that, when tested in a 4:1 or 1:1 mixture, by mass, with cellulose, exhibits a mean burning rate ≥ the mean burning rate of a 1:2 mixture, by mass, of calcium peroxide and cellulose
