No. Date Comments,National foreword,This British Standard is the official English language version of EN 12329:2000.,It supersedes BS 1706:1990 which is withdrawn.,CAUTION EN 12329 was approved as a European Standard as it received the,requisite support amongst the 19 member bodies of the European Committee for,Standardization (CEN). The UK therefore has an obligation to implement EN 12329,as its national standard and to withdraw BS 1706 with which it conflicts. However,attention is drawn to the fact that the UK did not support this standard on the basis,of possible safety implications, these being related to the commencement of heat,treatment as described in clause 6. The UK concern is that once a sub-microscopic,crack forms in the coated article, at present there is no means for its detection and,it cannot be aremovedo. Following the initiation of a sub-microscopic crack no,subsequent heat treatment can repair the damage already sustained. It is essential,therefore that the delay in applying heat treament is as short as practicable. The UK,recommendation therefore was to amend the requirement in clause 6 to aheat,treatment shall commence as soon as possible, preferably within 1 h, but not later,than 3 h after platingo in accordance with those conditions given in ISO 9588. The,recommendation was not accepted by the CEN Technical Committee responisble,for the development of EN 12329.,The UK participation in its preparation was entrusted to Technical Committee,STI/33, Electrodeposited and related coatings, which has the responsibility to:,D aid enquirers to understand the text;,D present to the responsible European committee any enquiries on the,interpretation, or proposals for change, and keep the UK interests informed;,D monitor related international and European developments and promulgate,them in the UK.,A list of organizations represented on this committee can be obtained on request to,its secretary.,Cross-references,The British Standards which implement international or European publications,referred to in this document may be found in the BSI Standards Catalogue under the,section entitled aInternational Standards Correspondence Indexo, or by using the,aFindo facility of the BSI Standards Electronic Catalogue.,A British Standard does not purport to include all the necessary provisions of a,contract.
