JB/T8372-96
No similar ISO standards were found during the formulation of this standard. This standard was formulated based on relevant domestic product classification standards and machine tool product model compilation methods.
This standard has a normative and guiding role in the design, development, operation and sales of measuring tools and measuring instruments. This standard divides geometric measuring instruments into four levels: major categories, minor categories, varieties and product names. At the same time, the characteristic code, variant code and main parameters and secondary parameters are used to specify the product model. This standard will be implemented from July 1, 199%6. This standard is proposed and managed by the National Technical Committee for Standardization of Measuring Tools and Meters. The responsible drafting unit of this standard is Chengdu Tool Research Institute of the Ministry of Machinery Industry. The main drafter of this standard is Han Chunyang. This standard was first issued on April 22, 199%6. 1 Scope

Method for compiling geometric measuring instrument models
This standard specifies the method for compiling geometric measuring instruments (hereinafter referred to as measuring instruments). This standard is applicable to the compilation of measuring instrument models. 2 Classification of measuring instruments
JB/T8372-96
Measuring instruments are divided into ten categories according to their use and structural performance (see Table 1). In addition, "measuring chain and its components" and "general measuring instrument components and accessories" are listed as a category in Table 1.
2.1 Length measuring instrument
Generally used for measuring length in a plane. Angle measuring instrument
Generally used for measuring angle in a plane. 2.3 Shape and position error measuring instrument
Specially used for measuring shape and position error. 2.4 Surface quality measuring instrument
Specially used for measuring surface geometric parameters such as surface roughness and waviness. 5 Three-coordinate measuring machine
Specially used for measuring spatial coordinates.
5 Gear measuring instrument
Specially used for measuring gear geometric parameter values ​​2.7 Thread measuring instrument
Specially used for measuring thread geometric parameters. 2.8 Active measuring instrument
Specially used for online measurement and control in the machining process. Approved by the Ministry of Machinery Industry on April 22, 1996
Implementation on July 1, 1996
2.9 Special inspection machines and sorting machines
JB/T 8372-96
Special inspection machines are measuring instruments used to measure one or more geometric parameters of specific parts and determine whether the parts are qualified or not. Sorting machines are measuring instruments that automatically group parts according to the required dimensions based on the measurement results. 2.10 Other measuring instruments
Measuring instruments other than the above-mentioned measuring instrument categories,
2.11 Measuring chain and its components
A complete part composed of a series of units that constitute the measurement signal from input to output channel. The functional units that make up the measuring chain are called components.
2 General devices and accessories
Refers to the general functional components, standard components and measuring components of measuring instruments. 3. Indication of measuring instrument model
1“口” indicates capital Chinese phonetic letters: 2“△” indicates Arabic numerals:
3No indication when there is no code in brackets:
4All codes should be written continuously.
3.1Class code
Variant code
General characteristic code
Second parameter code
Main parameter
Product name code
A subclass and variety code
Class code
The class code is indicated by one capital Chinese phonetic letter (see Table 2), which is placed at the first position of the model. Table 2
3.2 Sub-category and variety code
JB/T8372-9
Various types of measuring instruments, measuring chains and their components, general devices and accessories are divided into several sub-categories according to their specific uses, principles and structures, and each sub-category includes several varieties. Sub-categories and varieties are represented by a capital Chinese phonetic letter, which is placed after the category code. 3.3 Product name code
is used to represent specific products in the same variety. Its code is represented by capital Chinese phonetic letters except I and O. 3.4 Main parameters
Main parameters represent the main specifications or other main technical parameters of measuring instruments, measuring chains and their components, general devices and accessories, and are expressed in Arabic numerals. The length unit is millimeter, and the angle unit is not uniformly specified. Except for the main parameters of three-dimensional coordinate measuring machines, which are expressed in converted values, other main parameters do not use converted values. When the main parameter value is less than 1, it should be expressed in numbers after the decimal point.
When the resolution or division value is a length value and is used as the main parameter, the code in Table 4 is used to represent the main parameter. 3.5 Second parameter
When the main parameters are the same but the resolution or division value is different, the second parameter is used to distinguish them. The second parameter only represents the resolution or division value of the measuring instrument, and its code is as specified in Table 3.
Resolution or division value
Resolution or division value
General characteristic code
Used to indicate the form of the reference measurement chain adopted by the measuring instrument, its code is represented by a capital Chinese phonetic letter (see Table 4). Table 4
General characteristic
3.7 Variant code
Induction synchronizer
When only part of the structure and performance of the original model measuring instrument is changed, a variant code is added to indicate it. The variant code uses the sequence number of Arabic numerals and is placed after the general characteristic code. If there is no general characteristic code, "two" is added to separate it from the previous number. 4 Measuring instrument model compilation table
