Preface

This is the third edition of CSA P.5, Test method for measuring per-cycle energy consumption, energy factor, and low power mode energy consumption of residential gas clothes dryers. It supersedes the previous editions, published in 1997 and 1993 under the title Testing Method for Measuring Per-Cycle Energy Consumption and Energy Factor of Domestic Gas Clothes Dryers.

Scope

1.1
This Standard specifies the test method to measure per-cycle energy consumption and the calculations required to determine the energy factor of low power residential gas clothes dryers.

1.2
This Standard applies to compact size and standard size gas clothes dryers for use in residential applications.

1.3
This Standard does not apply to the construction and performance safety of residential gas clothes dryers.
Note: Construction and performance safety are addressed in ANSI Z21.5.1/CSA 7.1.

1.4
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; "may" is used to express an option or that which is permissible within the limits of the Standard; and "can" is used to express possibility or capability. 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. Legends to equations and figures are considered requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
