"ASTM" means the American Society for Testing and Materials; (ASTM)

"chronic toxic effect" means an adverse effect to the health of a person or test animal that develops

2. from prolonged or repeated exposure to a toxic substance under conditions that do not produce that effect from a single exposure; (toxicité chronique)

"dust" means solid airborne particles that are mechanically generated; (poussières)

"flame projection" means the ignited discharge of the pressurized contents of an aerosol container; (projection de la flamme)

"flashback" means that part of a flame projection that extends from its point of ignition back to the aerosol container; (retour de flamme)

"flash point" means the minimum temperature at which a liquid gives off vapour in sufficient concentration to ignite in test circumstances; (point d'éclair)

INTERPRETATION / DISCUSSION of SECTION 32

Part IV of the Controlled Products Regulations lists the scientific criteria which define controlled products; (see sections 34 to 66).

Definitions for terms used throughout the CPR are found in section 2. Definitions related to classification under WHMIS and, hence, used only in Part IV of the CPR, are found in section 32.
