1.2 In addition to the applicable requirements of this Standard, the requirements of CSA Z62.3 apply to all chain saws. The requirements specified in CAN/CSA-C22.2 No. 147 apply to electrical (Class 2) chain saws.
1.3 In CSA Standards, .shall. is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; .should. is used to express a recommendation or that which is advised but not required; and .may. is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
