4、s secretary.Additional informationBS EN 12899-2:2007 fully takes into account the requirements of the European Commission Mandate M/111, Circulation fixtures, given under the EU Construction Products Directive (89/106/EEC).BS EN 12899-2:2007 is a standard which sets down performance values (classes)
5、 rather than a method of manufacture. It has, in most cases, several performance classes for each characteristic.Some of these classes have a range of values. A manufacturer can supply a product that has the lowest value and still meet that class. Purchasers need to be aware of this when specifying
6、requirements.BS EN 12899-2:2007 gives guidance and background information to manufacturers of transilluminated traffic bollards on the use of BS EN 12899-2:2007. In particular it provides guidance in relation to the information that a manufacturer requires from purchasers. This would enable transill
7、uminated traffic bollards to be designed and manufactured on the basis of that information whilst conforming to BS EN 12899-2:2007.Information on visual and physical performance classes is also included.Recommended classes for visual and physical performance properties considered most suitable for U

26、BS EN 12899-2:2007EN 12899-2:2007 (E) 4 Introduction This European Standard is designed for use by road authorities. It can also be used by private developers who wish to use signs on their own land similar to those used on public highways. It can be used to implement type approval and certification
27、 testing. It derives from performance requirements and test methods published in CEN, CENELEC, CIE and ISO documents together with standards of the CEN member organizations. BS EN 12899-2:2007EN 12899-2:2007 (E) 5 1 Scope This Part 2 of EN 12899 specifies requirements for new transilluminated traffi
28、c bollards (TTBs) including their fixing, which may incorporate traffic signs (type 1 TTB) or may support traffic signs (type 2 TTB) to be used in traffic circulation areas. It covers performance requirements and test methods. Colorimetric and retroreflective properties as well as luminance of trans
29、illuminated illuminated portions are specified taking into account CIE recommendations. Structural requirements for TTBs include performance under static and dynamic loading. Provision is made for safety in use, including vehicle impact. Devices of similar function, but without transillumination or
30、less than 600 mm in height, are not covered. NOTE Foundations are not specified in this standard but should be adequate to support the loads to be carried. Unless otherwise stated, clauses in this standard apply to both type 1 and type 2 TTBs. 2 Normative references The following referenced document
