JBS CERTIFICATION MARK PROGRAMME

The general policies of the JBS Certification Mark Programme are as follows:

- The JBS provides certification services for manufacturers participating in the programme and

licensed to use the gazetted JBS Certification Marks to indicate conformity with Jamaican

Standards.

- Where feasible, programmes will be developed to meet special requirements of the submitter.

Where applicable, certification may form the basis for acceptance by inspection authorities

responsible for enforcement of regulations.

- In performing its functions in accordance with its policies, JBS will not assume or undertake any

responsibility of the manufacturer or any other party.

Participants in the programme should note that in the event of failure to resolve an issue arising from

interpretation of requirements, there is a formal appeal procedure.

Further information concerning the details of the JBS Certification Mark Programme may be obtained

from the Bureau of Standards, 6 Winchester Road, Kingston 10.

National foreword

This standard is an adoption of and is identical to ASTM A992/A992M – 11(2015) Standard Specification for Structural Steel

Shapes published by ASTM International.

Scope

1.1 This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes.

1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such

requirements apply only when specified in the purchase order.

1.3 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See

Appendix X3 of Specification A6/A6M for information on weldability.

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the

SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used

independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5 The text of this specification contains notes or footnotes, or both, that provide explanatory material; such notes and footnotes, excluding

those in tables and figures, do not contain any mandatory requirements.

Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For

dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any

amendments) applies.

Standards Council

The Standards Council is the controlling body of the Bureau of Standards Jamaica and is responsible for the policy and general administration of the Bureau.

The Council is appointed by the Minister in the manner provided for in the Standards Act, 1969. Using its powers in the Standards Act, the Council appoints committees for specified purposes.

The Standards Act, 1969 sets out the duties of the Council and the steps to be followed for the formulation of a standard.

Preparation of standards documents

The following is an outline of the procedure which must be followed in the preparation of documents:

1. The preparation of standards documents is undertaken upon the Standard Council’s authorisation. This may arise out of representation from national organisations or existing Bureau of Standards’ Committees or Bureau staff. If the project is approved it is referred to the appropriate

sectional committee or if none exists a new committee is formed, or the project is allotted to the Bureau’s staff.

2. If necessary, when the final draft of a standard is ready, the Council authorises an approach to the Minister in order to obtain the formal

concurrence of any other Minister who may be responsible for any area which the standard may affect.

3. The draft document is made available to the general public for comments. All interested parties, by means of a notice in the Press, are invited to

comment. In addition, copies are forwarded to those known, interested in the subject.

4. The Committee considers all the comments received and recommends a final document to the Standards Council

5. The Standards Council recommends the document to the Minister for publication.

6. The Minister approves the recommendation of the Standards Council.

7. The declaration of the standard is gazetted and copies placed on sale.

8. On the recommendation of the Standards Council the Minister may declare a standard compulsory.

9. Amendments to and revisions of standards normally require the same procedure as is applied to the preparation of the

original standard.

Overseas standards documents

The Bureau of Standards Jamaica maintains a reference library which includes the standards of many overseas standards organisations. These standards can be inspected upon request.

The Bureau can supply on demand copies of standards produced by some national standards bodies and is the agency for the sale of standards produced by the International Organization for Standardization (ISO) members.

Application to use the reference library and to purchase Jamaican and other standards documents should be addressed to:
