12、lity of the part is not compromised.If adequate space is not available,all suppliers,including original equipment manufacturers(OEMs),contract manufacturers(CMs),and original design manufacturers(ODMs),must notify HP in writing to determine the recycling impact of the unmarked part.All manufacturers
13、,including OEMs,CMs,and ODMs,are strongly encouraged to include physical marking,where practical,on all parts weighting less than 25 grams.Where physical marking on parts weighing less than 25 grams is required,this requirement will be noted on applicable drawings or procurement documents.3.2 Charac
14、ter size The physical marking code location,size,and process must be specified on the applicable part drawing.The marking process must be compatible with the recycling process.Marking should be placed where it is readily visible to product disassemblers.The preferred character size is 3mm to 5 mm hi
15、gh and with a profile depth of approximately 0.2 mm.On smaller parts where 3mm to 5 mm text is not possible,smaller text can be used.The materials identification text must be no smaller than the part number or identifier that is engraved on the part.If a part number or identifier is present on the p
16、art,there should also be adequate room for the plastic(polymer)identification symbols.3.3 Marking legibility Physical marking of plastic parts and products must remain legible during the entire part life.On molded plastic parts and products,integrally molded-in marking is preferred,with the provision for future 名师资料总结-精品资料欢迎下载-名师精心整理-第 2 页，共 16 页 -中国 RoHS 网,专注于,RoHS 认证,REACH 认证,RoHS 资讯,RoHS 法律法规及RoHS 体系建设,RoHS 专业论坛,传播 RoHS 资讯,共享绿色未来!原件载自：http:/5951-1741-1 29-Mar-2005 Page 3revisions.Production C
