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.

This Standard, which is based on the test methods in CAN/CSA-C361 and 10 CFR, specifies the test conditions, test procedures, measurement methods, and calculation procedures for determining the per-cycle energy consumption, energy factor, and low power mode energy consumption of residential gas clothes dryers.

This Standard was prepared by the Subcommittee on Energy Efficiency of Gas Clothes Dryers, under the jurisdiction of the Technical Committee on Gas Appliances and Related Accessories and the Strategic Steering Committee on Fuel Burning Equipment, and has been formally approved by the Technical Committee.

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.
