GB/T 22062-2020Microscopes - Graticules for eyepieces (English PDF)

Foreword

This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This Standard replaces GB/T 22062-2008 "Microscopes - Graticules for

oculars". Compared with GB/T 22062-2008, the main technical changes in this

Standard are as follows:

- added the dimensions of Type I graticule in Table 1 (see 3.1 of this Edition);

- added the content of reference standard in Table 2 (see 3.2 of this Edition);

- deleted the footnote f in Table 2 (see 3.2 of Edition 2008).

his Part uses redrafting method to modify and adopt ISO 9344:2016

"Microscopes - Graticules for eyepieces". The degree of consistency with ISO

9344:2016 is non-equivalent.

This Standard was proposed by China Machinery Industry Federation.

This Standard shall be under the jurisdiction of National Technical Committee

on Optics and Photonics of Standardization Administration of China (SAC/TC

103).
