ASME英文版数据报告/ASME产品注册? 请问哪位前辈有ASME 英文版数据报告,WORD和PDF版的都可以,我自己编辑了一份WORD版的,但是美国那边说我字体太小了,我把字体调整到他们的要求后,发现超出一张纸了,PDF的则是不能编辑字体大小(我们的厂名和地址加起来太长了,一行写不下,我的PDF软件不能编辑) 还有关于ASME产品注册的问题,他们所谓的原始数据报告是不是就是指AI签字的纸质版数据报告,是发到“1055 CRUPPER AVENUE COLUMBUS, OH 43229”这个地址吗? 是Donna Radcliff Registration Processing/EDT Coordinator National Board of Boiler & Pressure Vessel Inspectors这个人接收吗? 这个是美国那边发给我的,说我的设备没有成功注册的原因,我看了一下,应该是说: 1、没有寄原始数据报告, 2、数据报告的第四行,National Board number,这个我原本编的是NB-001,他们说不能有前缀后缀,那改成001是不是就行了 3、说我字体太小,最起码要8号字体,封头和喷嘴两张表格里可以用7号字体 We have received the data reports that were mailed. They are going to be returned to you unregistered for the following reasons: The original data report was not sent. The National Board requires the original signed data report for registration. Please remove the "NB" prefix from the National Board Number on line 4. National Board Numbers cannot have prefixes or suffixes. The font size of the print on much of the report falls below our minimum requirements. The National Board requires the use of at least a 6 point font size in creating data report forms and an 8 point font size on any information provided on the form by your company (Arial 8 or comparable size in any other font style). The only exception to this will be in sections which have a table format (i.e. – heads and nozzles). In these sections a 7 point font will be acceptable if the data remains legible. Due to the number of reports and emails we get on a daily basis we are not able to pre-review data reports. Please let me know if you have any questions.
