General specification of analytical instruments
1 Scope
This document specifies terms and definitions, classification and naming of instruments, requirements, test methods, inspection rules and marking, packaging, transportation and storage of analytical instruments.
This document is applicable to all types of analytical instruments.
This document is also applicable to devices for sample processing, preparation, signal processing and transmission, and auxiliary analysis, which are used with instruments or form independent products.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 13966 and GB/T 6592 and the following apply.
3.1
quality property
description of the technical state of the instrument, generally consists of three parts: technical parameters, functions and performance characteristics
3.2
technical parameter
description of the main characteristics of the instrument (measuring object, measuring range, minimum detection quantity, input quantity, output quantity, etc.)
Note: When these characteristic parameters require quantitative assessment, they are instrument (quantity) indicators.
3.3
performance characteristic
quantitative description of the instrument performance (sensitivity, accuracy, repeatability, stability, etc.), which is the basis for the quantitative assessment of instrument inspection and delivery (payment)
Note: In the technical standards of instruments, there are corresponding inspection methods for each performance characteristic.
3.4
function
description of the ways and means (operating software, calibration method, data processing method, alarm method, signal transmission method, etc.) by which the specified performance and characteristics of the instrument achieve its intended use
Note: When there is a quantitative assessment requirement for a specific function of the instrument, this function is the instrument (value) index.
3.5
mean time between failure; MTBF
average value of time between two adjacent failures
Note: It reflects the time quality of the instrument, which is an index to measure the reliability of the instrument, and reflects the ability of the instrument to maintain its due performance and function within the specified time, in "h".
4 Classification and naming of instruments
4.1 Classification
4.1.1 Classification according to detection principle
According to the detection principle, it is classified into electrochemical instruments, optical instruments, chromatographic instruments, mass spectrometry instruments, spectral instruments, energy spectrum and ray instruments, thermal instruments, etc.
4.1.2 Classification according to applications
According to the applications, it is classified into laboratory instruments, portable or mobile instruments, online or process instruments, etc.
4.2 Naming
4.2.1 Naming principle
The naming of analytical instruments mainly considers the detection principle and measurement object, and uses the name appropriately according to the habit.
4.2.2 Naming of instruments
The definitions and naming methods of "meter", "analyzer", "scope", "system" and "instrument" are as follows:
a) Special analytical instruments for measuring the mass of a single substance (excluding gas) and assigning value should be called "meters", such as pH meter, salinometer, and viscometer;
b) Instruments whose measurement object are gas may be called "analyzer", such as carbon monoxide analyzer and carbon dioxide analyzer;
c) Analytical instruments that study the morphology of material surfaces by analyzing images may be called "scopes", such as transmission electron microscopes and scanning electron microscopes.
d) Analytical instruments, which are composed of sample processing, analytical instruments, data management and auxiliary facilities (or parts) and realize the whole process from sample extraction to output analysis results, are generally called "systems", such as air quality monitoring system and water quality monitoring system;
e) Analytical instruments other than a), b), c) and d) are usually (or generally) called "instruments";
f) Instruments for safety alarm, with only sound and light warning, are generally called "alarm instruments"; where there are other display modes, they are generally called "explosimeter, detecting instrument and detector".
