This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2001, and conflicting national standards shall be withdrawn at the latest by November 2001. This Europe
16、an Standard EN 13150 is applicable with date of publication (dop.) For workbenches for laboratories complying with a national standard before dop, this previous national standard may continue to apply for production and placing on the market until 2 years after dop. This standard does not apply to w
17、orkbenches for laboratories, which have been put into service in the laboratory before 2 years after dop. Annex A is normative. Annex B is informative. According to the CENICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this Europ
18、ean Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. I Scope This European Standard specifies safety requirements and test methods for workbenc
19、hes for laboratories including laboratory tables and gives recommendations for their dimensions. This European Standard applies to workbenches, movable tables and workbench shelves designed for use in research, educational, quality control and similar laboratories. This European Standard does not ap
20、ply to workbenches for pupils in scientific class rooms of schools. It does not apply to workbenches for special purposes, e.g. for heavy diagnostic or processing machines. It should be understood that fulfilling the requirements does not ensure that failure will not occur as a result of habitual mi
21、suse or after an excessively long period of service. The tests are designed to be applied to a stand- alone workbench that is fully assembled and ready for use. Page 3 EN 13150:2001 Requirements and test methods related to the fire safety of workbenches and to the resistance of the work surface are
22、not included in this European Standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated refere
23、nces, subsequent amendments to or revisions of any of these publications apply to this European standard only when incorporated in it by amendment or revision.
