The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been established has liaison with IsO, also take part in the work. sO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEc Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 2094 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 12, Textilefloor coverings. This third edition cancels and replaces the second edition (isO 2094:1986) clause 5 of which has been technically revised. @ISO1999 All rights reserved.

It is applicable to all types of textile floor coverings with a surface that is level in height and construction. It does not apply to other textile floor coverings unless the areas of different thickness or construction can be tested separately. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.
