CSA PLUS 4000-93

Preface

Purpose: This is the third edition of Construction Plus. It supersedes the previous editions, which were published in 1988 and 1990.

Construction Plus provides summaries of all CSA construction Standards and many construction-related Standards. Users of CSA's construction and construction-related Standards need to identify the basic content of each Standard quickly and accurately. Titles and simple subject indices alone do not reveal th e products covered or the requirements stated by the Standard. These summaries, key words and comprehensive indices will thus make CSA's construction and construction-related Standards much more accessible to the user.

Users of this Plus publication may also be interested in the CSA electrical Standards, which are summarized in Electrical Plus (CSA, Toronto, 1993).

Content of Summaries: Each page summarizes the purpose of the Standard, the products or services covered, the requirements, and the test methodology, together with a set of key words and a full bibliographic citation. The first paragraph comprises a summary of the Standard scope, preface, and content, as well as a listing of the products and services covered. Other paragraphs summarize the requirements and test methodology; where appropriate, the packaging, documentation, and marking requirements are mentioned. Where there are SI (metric) and yard-pound editions of Standards, the summary and its bibliography cover the SI edition.

Note: These summaries do not replace the Standards themselves, which remain the only source for specific information on the scope and requirements. Use the Order Form on the last page to obtain CSA publications cited in this edition.

Key Words and Index Terms: The key words have been selected from the controlled vocabulary of the Root Thesaurus (British Standards Institution, 3rd edition, 1988). This Thesaurus was chosen because it includes the range of subject matter covered by the Canadian Standards Association and because it is available in French as well as English. There is no equivalent North American technical and scientific thesaurus.

The Root Thesaurus, however, occasionally favours terms not used in Canada. For example, it gives ""roads"" rather than ""highways"". In such cases both the Root terms and the other key words are list ed with the summary.

Key words and principal concepts have been used to prepare a set of index terms for each Standard and to assemble the Product Ind ex for this publication. The CSA designation and summary may be identified under the appropriate index term headings; this makes it easier to determine what subject is common to the various Stand ards. The Standard Designation Index provides the page number for each summary.

New editions and new listings are noted in the Standard Designation In dex.
