From: Diego on 30 Oct 2007 11:07 Anyone familiar with this? I have a print from a customer with the note "DIMENSIONS WITHOUT TOLERANCE ARE ACCORDING TO GB/T1804-m." The part is a simple sheet metal angle so I'm not too nervous, but we've been bit before with unclear standards. I googled GB/T1804-m and didn't find anything useful. Thanks in advance for any help. Diego
From: <IYM> on 30 Oct 2007 11:38 This type of thing happens to me all the time...Odd spec callouts usually turn out to be your customer's internal documents/standards that you would know nothing about. Most companies create internal standards documents....Anyway, your best bet is to call up your customer for their spec that should have been included when they submitted the job.

The "-m" indicates the tolerance class. This standard is equivalent to ISO 2768-1. A copy is posted here: <http://www.chinavalveinfo.net/2005BZ/1/GB1804.doc> Keith

Please excuse my ignorance but this link opens a Word document with SimHei font. All I see is a few lines of English and then rows of squares representing text. Is there a translated version, or a font that displays this document in English? Diego |
