"Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents".
This document is Part 14 of GB/T 42125 "Safety requirements for electrical equipment
for measurement, control and laboratory use". The following parts of GB/T 42125 have
been issued:
- Part 10: Particular requirements for measurement equipment for insulation
resistance and test equipment for electric strength;
- Part 14: Particular requirements for automatic and semi-automatic laboratory
equipment for analysis and other purposes;
- Part 19: Particular requirements for electrically operated valve actuators.
This document replaces GB 4793.9-2013 "Safety requirements for electrical equipment
for measurement, control and laboratory use -- Part 9: Particular requirements for
automatic and semi-automatic laboratory equipment for analysis and other purposes".
Compared with GB 4793.9-2013, the main technical changes in this document are as
follows:
- Add the equipment not included in the scope of this document (see 1.1.2 of this
document);
- Change the biohazard symbols in Table 1 (see Table 1; Table 1 of Edition 2013);
- Add the requirements for marking of flow direction [see 5.1.5.101 c) of this
Edition];
- Delete equipment transportation, installation and assembly instructions (see 5.4.3
of Edition 2013);
- Change the overview, equipment operation, equipment maintenance,
decommissioning or disposal requirements (see 5.4.1, 5.4.4 Note, 5.4.101 of this
Edition; 5.4.1, 5.4.4 Note, 5.4.101 of Edition 2013);
- Delete moving parts, accessibility during normal use, and accessibility outside
normal use (see 7.2, 7.2.101, and 7.2.102 of Edition 2013);
- Add the exception requirements (see 7.3.2 of this Edition);
- Change the overview (see 8.1 of this Edition; 8.2.1 of Edition 2013);
- Delete toxic and harmful gases and substances (see 13.1 of Edition 2013);
- Add the requirements for biohazardous substances (see 13.101 of this Edition);
- Add overview (see 15.1 of this Edition).
This document identically adopts IEC 61010-2-081:2019 "Safety requirements for
electrical equipment for measurement, control and laboratory use - Part 2-081:
Particular requirements for automatic and semi-automatic laboratory equipment for
analysis and other purposes".
This document has made the following minimal editorial changes:
- To harmonize with the existing documents, change the name of this document to
"Safety requirements for electrical equipment for measurement, control and
laboratory use - Part 14: Particular requirements for automatic and semi-
automatic laboratory equipment for analysis and other purposes".

Safety requirements for electrical equipment for
measurement, control and laboratory use - Part 14:
Particular requirements for automatic and semi-automatic
laboratory equipment for analysis and other purposes
1 Scope and object
Clause 1 of IEC 61010-1 is applicable except as follows:
1.1.1 Equipment included in scope
Replacement:
Replace the text, except the first paragraph, by the following new text:
This document applies to automatic and semi-automatic laboratory equipment for
analysis and other purposes.
Automatic and semi-automatic laboratory equipment consists of instruments or systems
for measuring or modifying one or more characteristics or parameters of samples,
performing the complete process or parts of the process without manual intervention.
Equipment forming part of such a system is within the scope of this document.
Examples of equipment within the scope of this document include:
- analytical equipment;
- automatic sampler (pipettor, aliquoter);
- equipment for sample replication and amplification.
NOTE 1: In the case of analytical equipment, the complete process usually includes the following
steps:
- taking a specific quantity of the sample;
- preparing the sample by chemical, thermal, mechanical or other means;
- measurement;
Replace the first paragraph with the following new text:
Markings required by 5.1.2 to 5.2 shall be removable only with a TOOL or by
appreciable force and shall remain clear and legible under conditions of NORMAL USE,
and resist the effects of temperature and rubbing, and of solvent and reagents likely to
be encountered in NORMAL USE, including cleaning and decontaminating agents
specified by the manufacturer.
Addition:
Add the following new paragraph after the second paragraph:
