Preface
This is the third edition of CSA Standard C300. It has been retitled Capacity Measurement and Energy Consumption Test Methods for Refrigerators, Combination Refrigerator—Freezers, and Household Freezers to indicate that the material previously published as CSA Standard C359,.Energy Consumption, Freezing/Capability, and Capacity Measurement Test Methods for Household Freezers, is now included in C300. This edition replaces previous editions of C300, published in 1984 and 1978. This edition also replaces the previous edition Of-C359, published in 1979.
Maximum energy consumption limits are specified.
In this Standard some of the conversions from Imperial measure to Metric or the reverse; have been derived on the basis of reasonableness for measurement purposes, and are not necessarily direct hard or soft conversions.
Purpose
1.1
The purpose of this Standard is to establish a uniform and repeatable procedure or standard method for measuring specified product characteristics of household refrigerators and household -freezers, and to establish-certain minimum requirements in support of a consumer informative labelling program. The standard methods and the recommended levels Of performance where they appear, are intended to provide a means by which different brands and models of household refrigerators and household freezers may be compared and evaluated with respect to characteristics of significance in the design and use of these products.
1.2
This Standard is not intended to preclude the exercise of ingenuity in the design or improvement of household refrigerators and household freezers.
Scope
2.1
This Standard applies to household refrigerators, combination refrigerator-freezers, and household freezers, as defined in Clause 3, that are electrically operated and designed for a 6O Hz alternating current supply with a nominal voltage of 115 V.
2.2
This Standard covers definitions, methods for computing volumes and shelf areas, methods for determining volumes of special features, performance test procedures, methods for determining energy consumption with associated energy factors, and specifies maximum energy consumption limits.
2.3
The requirements in this Standard are not applicable to electrically operated refrigerators employing an absorption refrigeration system.
2.4
The energy consumption limits in this Standard apply only to household refrigerators and combination refrigerator-freezers with a capacity of 200 L (7 ft ) to 1100 L (39 ft ) inclusive, 3nd to freezers with a capacity of 100 L (3.5 ft3) to 350 L 3o ft inclusive.
