Draft Amendment to C22.1

1.1 General

This standard provides procedural requirements for airflow and static pressure measurements in residential ductwork systems. It also includes calculations for extrapolating static pressure for different airflows based on measured data.

1.2 Inclusions

This Standard applies to ductwork systems installed in housing and small buildings.

Note: In this Standard, housing and small buildings are as defined in Part 9 of the National Building Code of Canada.

1.3 Exclusions

This Standard does not provide calculations for specifying the maximum airflow capacity of a ductwork system. It is the sole responsibility of a system designer to interpret the results of the calculations in this Standard.

This Standard does not encompass equipment commissioning beyond the technical procedures for the measurement of airflow and static pressure.

This Standard does not provide detailed device-specific instructions for different brands of equipment. 

1.4 Terminology

In this Standard, “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; and “may” is used to express an option or that which is permissible within the limits of the Standard.

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.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.5 Units of measure

The values given in metric units are the units of record for the purposes of this Standard. The US customary unit values given in parentheses are for information and comparison only.

1.1 General

This standard provides guidelines on how to plan, deliver and evaluate energy behaviour programs.

1.2 Applications

This standard is applicable to all types of organizations, regardless of their size or the nature of their activities. It is applicable to all energy behaviours, including but not limited to influencing habits, energy technology investment and purchasing decisions, equipment maintenance, and energy literacy. 

1.3 Exclusions

This standard does not prescribe specific energy management strategies or techniques.

1.4 Terminology

In this Standard, “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; and “may” is used to express an option or that which is permissible within the limits of the Standard.

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.

Draft Amendment to C22.1

1.1

These requirements cover devices and systems intended for use in accordance with Annex A, Ref. No. 1, to reduce the risk of electric shock to the user from accessible parts, in grounded or isolated circuits for charging electric vehicles. These circuits are external to or on board the vehicle.

1.2

The devices and systems covered by these requirements are compatible with the designs of charging systems and vehicles where use is intended and are rated accordingly. To assure compatibility, the charging system, the vehicle, or both, are in accordance with the features contained in 1.3 - 1.5.

1.3

The type of vehicle covered by these requirements, including all accessible conductive parts on the vehicle, has one or more of the following:

a) Provision for the connection of an equipment grounding conductor during battery charging, unless the vehicle has a system of reinforced or double insulation or all of the circuitry on the vehicle is electrically isolated from the supply circuit

b) Provision for the connection of ground-monitoring conductors, where required

c) Reinforced insulation, or is double-insulated from the supply circuit, or

d) No direct connection between current-carrying conductors and the vehicle chassis.

1.4

These requirements cover devices and systems where the grounding path impedance of the charging system to the vehicle is less than or equal to the impedance of the ungrounded conductor or conductors.

1.5

These requirements cover devices and systems where a continuous current less than 70 mA RMS is available from any accessible part of the charging system.

1.6

Devices covered by these requirements are intended to interrupt the electric circuit to the load when:

a) A fault current to ground exceeds some predetermined value that is less than that required to operate the overcurrent protective device of the supply circuit

b) The grounding path becomes open-circuited or becomes an excessively high impedance, or

c) A path to ground is detected on an isolated (ungrounded) system.

1.7

These devices and systems are intended to be applied on electrical systems or include derived systems that are:

a) Either end-grounded or centrally grounded when the operating voltage is 150 Vrms or less

b) Centrally grounded when the operating voltage is greater than 150 Vrms, or

c) Isolated (ungrounded).

1.8

Charging circuit-interrupting devices covered by these requirements are investigated for their ability to provide protection based on:

a) The type of current (60 Hz AC, DC, a combination of AC and DC, or AC at frequencies greater than 60 Hz) present in the circuit to be protected, and

b) Voltage.

1.9

In Mexico and the US, these requirements do not cover ground-fault circuit-interrupters (GFCIs) intended for use as personnel protection in accordance with the national electrical codes on grounded 120 Vrms or 127 Vrms to ground, 60 Hz circuits. Such devices are covered under Annex A, Ref. No. 2.

In Canada, these requirements do not cover ground-fault circuit-interrupters (GFCIs) in accordance with the national electrical code on grounded 120 Vrms or 127 Vrms to ground, 60 Hz circuits. Such devices are covered under Annex A, Ref. No. 2.

1.10

This Standard includes the Scope, Definitions, and Description of Requirements, including the required features of protection systems. The standards in Annex A, Ref. No. 3 contain the Performance and Construction requirements for protective devices that would become a part of a charging system.

1.1 General

This Standard provides requirements and guidance related to the performance of periodic safety reviews (PSRs) for nuclear power plants (NPPs).
