1.8 Special construction provisions applicable to a clothes dryer designed for use with an optional listed conversion kit are outlined under Annex A, Provisions for listed gas appliance conversion kits (optional).Also see Clause 4.22.13.
1.9 This Standard contains SI (Metric) equivalents to the yard/pound quantities, the purpose being to allow the Standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units - Part 1: General (Standard for use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI 10 or ISO 80000-1:2009 Quantities and units一Part 1: General are is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both are to be provided.
1.10 In this Standard,“shall" is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the standard;“should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.
Connection一a diagram that shows the connection of an installation or its component devices or parts. It may cover internal or external connections, or both, and contains such detail as is needed to make or trace connections that are involved. The Connection Diagram usually shows general physical arrangement of the component devices or parts.
Schematic一a diagram that shows, by means of graphic symbols, the electrical connections and functions of a specific circuit arrangement. The Schematic Diagram facilitates tracing the circuit and its functions without regard to the actual physical size, shape, or location of the component devices or parts.
Ladder form of schematic一a diagram drawn in the form of a vertical ladder. The outer vertical lines represent the electrical supply conductors. The horizontal steps represent each individual circuit with all component devices.
Heating value (total)一the number of British Thermal Units produced by the combustion, at constant pressure, of 1 cubic foot (0.03 m3) of gas when the products are cooled to the initial temperature of the gas and air, when the water vapor formed during combustion is condensed, and when all the necessary corrections have been applied.CSA 7.1 pdf download.
