Preface:

This is the fourth edition of CSA C22.2 No. 0.15, Adhesive labels. It supersedes the previous editions published in 2001, 1995, and 1990. This Standard is one of a series of Standards issued under Part II of the Canadian Electrical Code.

It is intended that this Standard be referenced by interested groups, such as the Subcommittees of Part II of the Canadian Electrical Code, in their standards-writing activities. The utilization of the test procedures included in this Standard will serve to standardize the diversified test requirements for the various types of adhesive labels and nameplates.

Significant changes from the third edition include the following:
a) the document has been restructured for better flow and organization;
b) abrasion requirements in Clause 8.2.11 have been revised to be in line with adhesive labeling materials that are used today; and
c) Table 1 has been added for clarification of heat-cold-humidity requirements.

Scope:

1.1
This Standard applies to permanent adhesive labels and nameplates intended for use indoors or outdoors on application surfaces that are essentially clean, smooth, flat, or simple curved.
* See Annex A

1.2
This Standard includes requirements for legibility of text and other mandatory information and adhesion of the label when subjected to various environmental conditions.

1.3
This Standard also includes provisions for the testing of unprinted label stocks, overlaminations, and laminating/transfer adhesives.

1.4
General requirements applicable to this Standard are given in the latest edition of CAN/CSA-C22.2 No 0.

1.5
The values given in SI (metric) units are the standard. The imperial values given in parenthesis are for information only.

1.6
In this Standard, "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. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non mandatory) to define their application.
