Preface This is the first edition of CSA R7005, the second edition of UL 7005, and the most recent version of AHAM 7005, Sustainability Standard for Household Clothes Drying Appliances. This harmonized standard was prepared by the Association of Home Appliance Manufacturers, (AHAM), CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee are gratefully acknowledged. This Standard was prepared by CSA Technical Committee on Sustainability of Household Appliances under the jurisdiction of CSA Strategic Steering Committee on Business Management and Sustainability and has been formally approved by the CSA Technical Committee. The environmental performance of household clothes drying appliances is commonly evaluated on the single environmental attribute of electricity consumption during use. This Standard takes a multi-attribute, life cycle approach to measuring a broad spectrum of environmental and social impacts of household clothes drying appliances as a means of assessing sustainability performance. The multi-attribute approach was developed using representative product life cycle assessment (LCA) information along with other key factors such as hot-spot or hot-button analyses influencing product environmental performance. The attributes and criteria in this Standard are drawn from a much larger list and reflect the understanding of the attributes and criteria that are most prominent in sustainable performance and over which the manufacturers of these products have control. This approach, detailed in Annex A, determined the environmental attributes of household clothes drying appliances for inclusion in this Standard. The authors acknowledge that revisions to this standard will be considered periodically and that future editions may consider a broader range of sustainability criteria. It has been contemplated by all parties that this Standard will be updated to reflect new U.S. Department of Energy or Natural Resources Canada minimum energy performance standards for household clothes drying appliances products. Many of the measurements included in this Standard are unique and have not been conducted on other appliance categories. The Standard\'s committees expect to learn much from the application of this Second Edition in subsequent years. The use of this Standard and self-assessment by household clothes drying appliances manufacturers and external third-party assessment bodies will be used to improve the Standard in drafting the second and subsequent editions. This Standard was written specifically for products placed on the market in the United States and Canada. At the present time, a number of the calculations are based on systems and designs of products in North America. Scope 1.1 This Standard covers clothes drying appliances for households included within the scope of the U.S. Department of Energy (DoE) and Natural Resources Canada (NRCan) minimum energy performance requirements. This includes the following product categories: a) electric clothes dryers; and b) gas clothes dryers. NOTE: Presently gas dryers are not a regulated product in Canada for energy efficiency. 1.2 The clothes dryers covered by this definition include: a) vented gas; NOTE: Presently gas dryers are not regulated product in Canada for energy efficiency. b) ventless or vented electric (standard), 124.6 L (4.4 ft3) or greater capacity; c) ventless or vented electric, compact (120 V) (less than 124.6 L (4.4 ft3) capacity); d) vented electric, compact (240 V) (less than 124.6 L (4.4 ft3) capacity); and e) vented electric, compact (240 V) (less than 124.6 L (4.4 ft3) capacity). 1.3 This Standard excludes water-cooled electric ventless clothes dryers.
