GB/T 22093-2018Internal micrometer with electronic digital display (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 22093-2008 "Electronic Digital Internal Diameter Micrometer". This standard is compared with GB/T 22093-2008, except for editing In addition to the series of changes, the main technical changes are as follows:

---Expand the measurement range of the electronic digital internal diameter micrometer to 1000mm (see Chapter 1, Chapter 1 of the.2008 edition);

--- Modified the definition of electronic digital display digital display device (see 3.1,

3.1 edition of.2008);

--- Increased the definition of the electronic digital display internal micrometer (see 3.2);

--- Increased the electronic digital internal diameter micrometer with a micrometer screw pitch of 2mm (see 4.2.1);

--- Added provisions for the measurement range of the electronic digital internal diameter micrometer (see 5.5);

--- Revised the requirements and specified values of the maximum allowable error of the indication (see

5.13 and Table 2,

5.13 and Table 2 of the.2008 edition);

--- Increased the maximum allowable error of the indication value of the electronic digital internal diameter micrometer with a range greater than 25mm (see 5.13.1);

--- Increased the inspection method for the locking change of the A-type electronic digital display internal micrometer (see 6.1);

--- Revised Note 2 of the Indexing Error Test Method (see 6.3.1,

6.2.1 of the.2008 edition);

1 Scope

GB/T 22093-2018 is the Chinese national standard on internal micrometer with electronic digital display, in the field of metrology and measurement. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 May 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2018. Classification: ICS 17.040.30, CCS J42. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions, types and basic parameters, requirements, test methods, test methods, electronic digital internal diameter micrometers. Logo and packaging. This standard is applicable to the number of electrons with a resolution of 0.001mm, a range of less than or equal to 100mm, and an upper limit of the measurement range to 1000mm. The internal diameter is micrometer. Refer to Appendix A for the A-type electronic digital internal diameter micrometer with a measuring range of 1000mm~6000mm.
