GB/T 22056-2018Microscopes -- Marking of objectives and 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 22056-2008 "Laboratory of Objectives and Eyepieces of Microscopes". Compared with GB/T 22056-2008, mainly

The changes are as follows.

--- Added Chapter 2 normative references;

--- Table 1 adds an example of the cover glass thickness range of 0.14mm~0.20mm; the sign of the number of fields of view of the objective lens is increased;

--- Table 2 adds the mark of the correction ring, and the contents of the note have been modified as appropriate;

--- In Table 3, the footnote was changed to Note, and the original Note 2 was deleted;

--- Table 5 removes the mark of the correction type.

This standard uses the redrafting method to modify the use of ISO 8578.2012 "marks of microscope objectives and eyepieces."

There are technical differences between this standard and ISO 8578.2012, and the terms involved in these differences have been passed through the margins on the outer side of the page.

The vertical single line (|) is marked.

The main technical differences between this standard and ISO 8578.2012 and their reasons are as follows.

--- Increased the scope of application of the standard.

---About the normative reference documents, this part has made technical adjustments to adapt to China's technical conditions, specific

The national standards are as follows.

* Replace ISO 8036 with GB/T 26600 modified to international standards.

This standard was proposed by the China Machinery Industry Federation.

This standard is under the jurisdiction of the National Optical and Photonics Standardization Technical Committee (SAC/TC103).
