ISO/CEN PARALLEL ENQUIRY

This draft International Standard is a draft standard developed within the European Committee for

Standardization (CEN) and processed under the CEN-lead mode of collaboration as defined in the

Vienna Agreement. The document has been transmitted by CEN to ISO for circulation for ISO member

body voting in parallel with CEN enquiry. Comments received from ISO member bodies, including those

from non-CEN members, will be considered by the appropriate CEN technical body. Should this DIS be

accepted, a final draft, established on the basis of comments received, will be submitted to a parallel two-

month FDIS vote in ISO and formal vote in CEN.

In accordance with the provisions of Council Resolution 15/1993 this document is circulated in

the English language only.

Conformément aux dispositions de la Résolution du Conseil 15/1993, ce document est distribué

THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE

REFERRED TO AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.

IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES, DRAFT

INTERNATIONAL STANDARDS MAY ON OCCASION HAVE TO BE CONSIDERED IN THE LIGHT OF THEIR POTENTIAL TO BECOME STANDARDS TO

WHICH REFERENCE MAY BE MADE IN NATIONAL REGULATIONS.
