1 Scope


This Standard covers the protection from lightning of:

recreational, residential, insititutional, medical, agricultural, industrial, commercial, military, and telecommunications buildings and structures;

tall, slender structures such as smoke stacks, silos, tanks, towers, masts and poles; and

immobile property such as equipment, tents, fences, trees, and solar arrays;

high-risk structures with dangerous contents such as explosives and flammable goods.


This Standard covers the protection from lightning of structures housing electrical generation, transmission, and distribution systems, as well as structures housing communication systems, but not the equipment or installation requirements for such systems.


This Standard does not cover installation requirements for early streamer emission systems or charge dissipation/charge transfer systems.


This Standard also contains non-mandatory sections devoted to the nature of lightning and the general principles upon which lightning protection is based, so that the user of the Standard will be able to assess the need for lightning protection in the case of any given structure (see Appendices).


The values given in SI (metric) units are the standard. The values given in parentheses are for information only.


Clause 2 contains a list of standards referenced in this Standard, and sources from which these reference standards may be obtained.

1 Scope

1.1 Compressor types

This Standard applies to vent gas from reciprocating compressor rod packings and centrifugal compressor seals including any auxiliary and support systems that are required for proper operation of the packing or sealing system.  

The procedures considered in this Standard include vent gas line tracing and alternate flow path identification, minimizing backpressure, vent gas loss management, measurement procedures, calculations, and data recording.

1.2 Exclusions

This Standard does not apply to:

       non-routine venting (e.g. compressor casing blowdown vents, engine starter vents);

fugitive emission management programs;


       measurement devices that do not internally admit the entire vent gas flow volume in order to take a measurement (i.e. remote sensing technologies);

quantification of unburnt hydrocarbon or methane emissions in combustion devices such as flares, engines or boilers; and

area based sources of volatile organic compounds or methane emission such as landfills, sewage treatment facilities, ponds, tailings ponds, coal and oil sands open mine face emissions and underground coal mine emissions. 

1.3 Gauge pressure

All references to "kPa" throughout this Standard are to be considered gauge pressures unless otherwise specified.

This Standard specifies the methods for determining the uniform energy factor for electric storage tank water heaters and heat pump water heaters.

This Standard establishes minimum energy efficiency levels for electric storage tank water heaters and heat pump water heaters.

This Standard applies to
a) electric storage tank water heaters
i) with volumes of 7.6 to 454 L (2 to 120 US gal);
ii) having electric heater elements with power inputs ≤ 12 kW; and
iii) designed to heat and store water at a thermostatically controlled temperature equal to or less than 82 ºC (180ºF); and
b) heat pump water heaters that have
i) a maximum current rating of ≤ 24 A; (including the compressor and all  auxiliary equipment such as fans, pumps, controls, and, if on the same circuit, any resistive elements
ii) A maximum wattage rating ≤ 15kW
iii) a single-phase maximum voltage of ≤ 250 V; and
iv) with volumes of 7.6 to 454 L (2 to 120 US gal);
     v) rated storage volume ≤ 454 L (120 US gal);   

This Standard does not apply to high-temperature water heaters.

The tests contained in this Standard are not intended to represent actual efficiencies realized in the field. Instead, these tests provide a standardized method of comparing performance. 

This Standard is written in SI units. The values given in parentheses are for information only. The SI values have been calculated from the US Customary Units measurements found in the US Department of Energy publication 10 CFR, Part 430, appendix E, subpart

1.1 General


These procedures apply to unitary air conditioners and heat pumps that are

a) factory-made;
b) air-source and air-sink;
c) single-split systems with matching assemblies or single package for use in ducted and/or non-ducted distribution systems;

d) intended for space-heating and/or air-conditioning applications in buildings;
e) electrically driven, mechanical, vapour-compression-type systems; and
f) rated below 65,000 Btu/h (19.0 kW) heating or cooling at standard rating conditions, in accordance with Clause 5.2.

Note: This includes space-constrained single-package or split-system and small-ducthigh-velocity central air conditioners and heat pumps matching assemblies of the type classified in Clause 1.2 and intended for air-conditioning and space-heating applications in buildings.


These procedures do not apply to the following:

a) water to air and/or water units; and
b) heat recovery.

1.2 Unitary equipment

Unitary equipment within the scope of these procedures is outlined in Table 1.

1.3 Terminology

In these procedures, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with these procedures; “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 these procedures; 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.

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

1.4 Units of measurement

The values given in IP (inch-pound) units are normative. Metric values given in parentheses are for information only.
