CSA C22.1-12 Handbook provides background information on the reasons behind the requirements in the Canadian Electrical Code, Part I, and gives an explanation of each Rule in plain, easy-to-understand language. The Handbook is intended to provide a clearer understanding of the safety requirements of the Code.

C22.1-12 Handbook is not meant to form a code of mandatory requirements. The mandatory language ("shall") that is used in the CE Code, Part I, has not been used here. Care has been taken to ensure that the intent of the Code Rules is clear to the users of the Handbook. However, users of the Handbook must not under any circumstances rely on it to determine the current requirements of the Code. As always, reference must be made to the Code itself and any local amendments. CSA does not assume responsibility for any errors or omissions resulting from the information contained in this Handbook.

The Rules in the CE Code, Part I, are divided into two groups. Sections 0 to 16 and 26 are considered General Sections, and the other Sections supplement or amend those General Sections. Therefore a requirement in the supplementary Sections takes precedence over a general requirement. For example,

Rule 12-1008 requires three threads to be engaged when making a threaded connection, whereas Rule 18-106 requires five threads to be engaged when making a threaded connection in a Class I, Zone 1 area.

Section 4 permits the use of aluminum conductors, but Rule 32-100 does not allow aluminum conductors to be used in fire alarm systems.

ANSI/ASSE Z590.3-2011

Prevention through Design: Guidelines for Addressing Occupational Hazards and Risks in Design and Redesign Processes

American Society of Safety Engineers / 23-Jan-2012 / 64 pages

This standard provides guidance on including prevention through design
concepts within an occupational safety and health management system. Through the
application of these concepts, decisions pertaining to occupational hazards and risks can be
incorporated into the process of design and redesign of work premises, tools, equipment,
machinery, substances, and work processes including their construction, manufacture, use,
maintenance, and ultimate disposal or reuse. This standard provides guidance for a life-cycle
assessment and design model that balances environmental and occupational safety and health
goals over the life span of a facility, process, or product.

NFPA (Fire) 268

Standard Test Method for Determining Ignitability of Exterior Wall Assemblies Using a Radiant Heat Energy Source, 2012 Edition

National Fire Protection Association / 02-Jan-2012 / 22 pages

Accurately assess fire risk by testing exterior wall assemblies according to the methodology presented in the 2012 NFPA 268.

Revised to include updated references, the 2012 NFPA 268: Standard Test Method for Determining Ignitibility of Exterior Wall Assemblies Using a Radiant Heat Energy Source describes a method to determine the propensity of ignition of exterior wall assemblies from exposure to 12.5 kW /m2 radiant heat in the presence of a pilot ignition source.

From instrumentation and documentation to safety precautions and calibration, this document provides testing laboratories and manufacturers with comprehensive testing guidance.

ASTM D2513-11c

Standard Specification for Polyethylene (PE) Gas Pressure Pipe, Tubing, and Fittings

ASTM International / 19-Dec-2011 / 16 pages

This specification covers requirements and test methods
for material dimensions and tolerances, hydrostatic burst
strength, chemical resistance, and rapid crack resistance of
polyethylene pipe, tubing, and fittings for use in fuel gas mains
and services for direct burial and reliner applications. The pipe
and fittings covered by this specification are intended for use in
the distribution of natural gas. Requirements for the qualifying
of polyethylene systems for use with liquefied petroleum gas
are also covered.

This specification does not cover threaded pipe. The plastic used to make the pipes and fittings shall be virgin plastic or reworked plastic having Plastics Pipe Institute (PPI) long-term hydrostatic design stress and hydrostatic design basis rating.

ASTM C902-11

Standard Specification for Pedestrian and Light Traffic Paving Brick

ASTM International / 01-Dec-2011 / 4 pages

1.1 This specification covers brick intended for use as paving material subjected to pedestrian and light vehicular traffic. The units are designed for use in pedestrian applications and vehicular areas that are subjected to low volumes of vehicular traffic, such as residential driveways and streets and commercial driveways (passenger drop-offs). The units are not intended to support heavy vehicular traffic covered by Specification C1272 or for industrial applications covered by Specification C410.

Note 1 – Heavy vehicular traffic is defined as high volumes of heavy vehicles (trucks having 3 or more axles) in Specification C1272.

1.2 The property requirements of this specification apply at the time of purchase. The use of results from testing of brick extracted from masonry structures for determining conformance or nonconformance to the property requirements (Section 4) of this specification is beyond the scope of this specification.

1.3 Brick are manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to a heat treatment at elevated temperatures (firing). The heat treatment must develop sufficient fired bond between the particulate constituents to provide the strength and durability requirement of this specification (see Terminology C1232).

1.4 The brick are available in a variety of sizes, colors, and shapes. They are available in three classes according to exposure environment and three types according to type of traffic exposure.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

IEC 60364-5-55 Ed. 2.0 b:2011

Electrical installations of buildings – Part 5-55: Selection and erection of electrical equipment – Other equipment

Edition: 2.0
International Electrotechnical Commission / 14-Dec-2011 / 53 pages

IEC 60364-5-55:2011 covers requirements for the selection and erection of low-voltage generating sets and for the selection and erection of luminaires and lighting installations intended to be part of the fixed installation. This second edition cancels and replaces the first edition, published in 2001, its Amendment 1 (2001) and its Amendment 2 (2008). The major technical changes with respect to the previous edition are:
– additional requirements for connection of luminaires to the fixed wiring;
– modification of requirements regarding the fixing of luminaires;
– inclusion of alternative solutions for connecting devices used for through wiring and for connection of luminaires to the supply;
– withdrawal of Clause 556, as IEC 60364-5-56 now covers this matter.
