1 Scope
This document specifies the terms and definitions, instrument classification and naming,
requirements, test methods, inspection rules and marking, packaging, transportation and
storage of analytical instruments.
This document applies to various types of analytical instruments.
This document also applies to sample processing, preparation, signal processing and
transmission, and auxiliary analysis devices that are used with instruments or form
independent products.

mean time between failure; MTBF
The average time between two adjacent failures.
NOTE. It reflects the time quality of the instrument, is an indicator for measuring the reliability of
the instrument, and reflects the ability of the instrument to maintain the required performance and
function within the specified time, and the unit is “h”.
4 Instrument classification and naming
4.1 Classification
4.1.1 Classification by test principle
According to the test principle, it is divided into electrochemical instruments, optical
instruments, chromatographic instruments, mass spectrometers, spectral instruments,
energy spectrum and radiation instruments, thermal instruments, etc.
4.1.2 Classification by application occasions
According to the application occasions, it is divided into laboratory instruments,
portable or mobile instruments, online or process instruments, etc.
4.2 Naming
4.2.1 Naming principles
The naming of analytical instrument products mainly considers the test principle and
the measuring object, and appropriately takes into account the habits.
4.2.2 Naming of instruments
The meaning and naming method of “meter”, “analyzer”, “microscope”, “system” and
“instrument” are as follows.
a) Special analytical instruments that measure the mass of a single substance
(excluding gas) and assign values should be called “meter”, such as pH meter,
salt meter, viscometer, etc.;
b) Instruments that measure gas can be called “analyzer”, such as carbon monoxide
analyzer, carbon dioxide analyzer, etc.;
c) Analytical instruments that study the morphology of the surface of substances by
analyzing images can be called “microscopes”, such as transmission electron
microscopes, scanning electron microscopes, etc.;
d) Analytical instruments that are composed of sample processing, analytical
instruments, data management and auxiliary facilities, etc. (or parts) to achieve
the whole process from sample extraction to output of analytical results are
generally called “systems”, such as air quality monitoring systems, water quality
monitoring systems, etc.;
e) Analytical instruments other than a), b), c) and d) are usually (or generally) called
“instruments”;
f) Safety alarm instruments that only have sound and light warnings are generally
called “alarms”; those with other display methods are generally called “explosion
detectors, testers, and detectors.”
5 Requirements
5.1 Working conditions of instruments
The working conditions of instruments include. normal working conditions, reference
working conditions, and extreme working conditions.
The conditions of use are as follows.
a) According to the design and use conditions of the instrument, refer to the
environmental conditions given in Table 1 of GB/T 11606-2007, and select all
quantities that will have a non-negligible impact on the quality characteristics of
the instrument and their reference values or reference value ranges as normal
working conditions. When it is not possible to fully comply with the provisions
of GB/T 11606-2007, the differences shall be indicated in the document.
b) When the evaluation of certain quality characteristics of the instrument needs to
exclude the influence of environmental factors, reference working conditions
shall be given (see Table 2 in GB/T 11606-2007).
c) If necessary, extreme working conditions shall be given.
5.2 Appearance and structure
The appearance and structure of the instrument shall meet the following requirements.
a) The appearance shall be neat, the color shall be uniform, and there shall be no
burrs;
b) The nameplate and logo shall be durable and clear, and the content shall comply
with the requirements of relevant laws and standards;
c) The fasteners shall not be loose, the various adjustment parts shall be flexible, and
the functions shall be normal;
d) The detachable parts of the instrument shall be easy to disassemble and assemble.
5.7.2 Special requirements
If necessary, special environmental requirements such as low pressure, mold, salt spray,
explosion-proof, etc. shall be specified by the product standard.
5.7.3 Transportation, transportation and storage
The circulation conditions shall be specified in the product standard. After testing in
accordance with the requirements of Clause 8, Clause 15, Clause 16, Clause 17 and
Clause 18 of GB/T 11606-2007, the packaging box shall not have large deformation
and damage, and the tested instrument shall not have mechanical damage such as
deformation, loosening, and peeling of the coating layer, and its performance
characteristics shall comply with the provisions of the product standard.
5.8 Reliability
If necessary, reliability indicators such as the mean time between failures shall be
specified.
5.9 Electromagnetic compatibility
If necessary, electromagnetic compatibility requirements shall be specified.
The instrument immunity and emission requirements shall be in accordance with GB/T
18268.1-2010.
5.10 Completeness
The completeness of the instrument and its accessories shall be specified in the product
