These are calibration standards. For example, Here is a document (http://www.tisi.go.th/lab/pdf_clb/c0042_e.pdf) that refers to them.

JIS B7502 Info (http://www.webstore.jsa.or.jp/webstore/Com/FlowControl.jsp?lang=en&bunsyoId=JIS+B+7502%3A1994&dantaiCd=JIS&status=1&pageNo=0).

JIS B7507 Info (http://www.webstore.jsa.or.jp/webstore/Com/FlowControl.jsp?lang=en&bunsyoId=JIS+B+7507%3A1993&dantaiCd=JIS&status=1&pageNo=0).

Stijloor.

I hope we are not having a language issue here.

JIS refer to Japanese Industrial Standards. Documents with designation: JIS X XXXX are standards issued by them.

JIS B 7507 is a calibration standard for Calipers
JIS B 7502 is for Micrometers

They can usually be purchased directly from from your national standards agency. As I pointed out in another of your earlier post, your local engineering university should have them and you can have a view there.
