Preface This is the fourth edition of CSA Z600, Safety of corded window covering products, which is an adoption, with Canadian deviations, of the identically titled ANSI/WCMA (American National Standards Institute/Window Covering Manufacturers Association) Standard A100.1-2012. This CSA Group Standard supersedes previous editions published in 2008, 2006, and 1999. Scope 1.1 The members of the Window Covering Manufacturers Association, Inc. (WCMA), recognizing that unfortunate accidents, including strangulation, have occurred among young children using certain products having flexible loops made or imported by members of the industry, have prepared this Standard in cooperation with the U.S. Consumer Product Safety Commission (CPSC). This Standard is not intended to inhibit, but rather to encourage the development of devices and methods that shall further improve the safety of products manufactured by industry members. Manufacturers and other users of this Standard are requested to submit suggestions for improvements to WCMA. Members of WCMA, in recognition of continuing improvements to be made, shall sponsor appropriate revisions to this Standard on a regular basis. 1.2 This Standard applies to all interior corded window covering products. The items covered include the products listed in 1.3 when used in all reasonably foreseeable environments where young children are present. 1.3 Window covering products covered include, but are not limited to, cellular shades, horizontal blinds, pleated shades, roll up style blinds, roller shades, Roman style shades, traverse rods, and vertical blinds. These products can be manufactured and distributed as either stock or custom products. (See Section 3 for definitions of these terms.)
