This is the second edition of CSA Standard W59.2, Welded aluminum construction. It supersedes the previous edition published in 1991 and CSA 5244-1969, Welded Design and Workmanship (Inert Gas Shielded Arc Processes), which was replaced by the 1991 edition.
This edition represents a major rework of the Standard in both format and content. The following is a brief description of some of the most significant changes to the current edition of CSA W59.2:
• the structure of this Standard has been modified to parallel CSA W59 where appropriate for ease of use;
• Clause 3 has been revised to add several new materials;
• Clause 5 includes new requirements for weld acceptance criteria;
• Clause 7 has been reworked to provide clarity on roles and responsibilities for welding inspection;
• Clause 8 has been added to provide comprehensive requirements for non-destructive testing;
• Clause 10 has been added to provide requirements for friction stir welding; and
• Annex A has been added to provide recommended joint geometries for aluminum welding.
This Standard was prepared by the Technical Committee on Welding of Bridges, Buildings, and Machinery and the Offshore Welding Task Group, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and has been formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

This Standard covers the manufacturing process requirements of fibre-reinforced polymer (FRP) bars or bars that are part of a grid for use in non-pre stressed internal reinforcement of concrete components of structures (e.g., bridges, buildings, and marine structures).
1.2
This Standard covers FRPs comprised of (a) glass, carbon, or aramid fibres; and (b) isophthalic polyester, vinylester, or epoxy resins.
1.3
This Standard covers FRP bars having nominally circular or square cross-section.
1.4
This Standard does not include FRP bars made of more than one type of fibre.
1.5
In this Standard, FRPs are classified on the basis of their fibres, strength, stiffness, and durability.
1.6
In CSA Standards, 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.

This is the first edition of CSA S345, Design and construction of steel storage racks. It replaces CSA S16, Annex N, prepared under the same title in 2019, which superseded the previous edition of Annex N in CSA S16-14 (update 1) published in 2016.
CSA published A344.1 and A344.2 in 2005 as a two-part document: a user guide and a design standard for steel storage racks. Following the withdrawal of CSA A344.2 in 2016, and its subsequent incorporation into CSA S16, this Standard has been developed as a stand-alone document. The contents of this new Standard are linked with both CSA A344 and CSA B335, which establish the requirements for a safe environment where steel storage racks and lift trucks are the primary equipment of the workplace.
No technical changes have been made to the content originating from CSA S16, Annex N. Editorial changes to this edition include the updating of referenced standards.
This Standard was prepared by the Technical Committee on Industrial Storage Racks, under the jurisdiction of the Strategic Steering Committee for Construction and Civil Infrastructure, and has been formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

The design and construction of electrical equipment for elevators and escalators presents complex requirements in the application of industrial control equipment and elevator equipment. With the need to have identical Canadian and U.S. requirements for this type of equipment, the applicable portions of CSA C22.2 No. 14 and UL 508 were reviewed and adapted to elevator equipment.
Highlights of B44.1:
Provides guidance to reduce the risk of injury and potential damage to property from fire and electrical shock
Harmonized standard combining applicable portions from CSA C22.2 No. 14 and UL 508 adapted for elevator equipment
Harmonized guidelines enable manufacturers to have their products certified by an approved testing laboratory in Canada or the United States and to have the certification ratified for acceptance in either country
Indented to reduce the risk of injury to persons and damage to property from fire and electrical shock

Concrete remains a fundamental basis for the Australian construction industry. It provides a number of
benefits – social, economic and environmental – that means it is a sustainable material.
This edition of Guide to Concrete Construction represents a major review of the volume. The contents
were last reviewed in 2002 and much has changed in the composition and specification of concrete.
The reader will notice changes in the structure and content of this volume to address these changes
and ensure a contemporary description of concrete – its composition and performance.
