Foreword
All technical contents of this section is mandatory.
GB 4793 "measurement, control and laboratory safety requirements for electrical equipment" is currently divided into seven parts.
--- Part 1. General requirements (IEC 61010-1);
--- Part 2. Particular electrical measurement and test requirements held and hand operated current sensors (IEC 61010-2-032);
--- Part 3. laboratory mixing and stirring equipment Particular requirements (IEC 61010-2-051);
--- Part 4. Particular requirements for laboratory use (IEC 61010-2-041) Autoclave treatment of medical material;
--- Part 5. Safety electrical measurement and test requirements of the handheld probe assembly (IEC 61010-031);
--- Part 6. Laboratory Particular requirements (IEC 61010-2-010) heating of materials;
--- part 7. Particular requirements for laboratory centrifuges (IEC 61010-2-020).
Note. The name of the section will change with changes in IEC standard names.
This is Part 7 GB 4793's.
This section is equivalent to using 61010-2-020 IEC .2006 "measurement, laboratory control and the second section 2-020 Safety requirements for electrical equipment
Points. Particular requirements for laboratory "with centrifuges (in English). Technical content, structure, and text expressions and IEC 61010-2-020.
2006 exactly the same. For ease of use, the present editorial changes made the following section.
"." --- replaced by a decimal decimal comma ",";
--- omitted IEC 61010-2-020.2006 contents Foreword and "Appendix H (informative) defined Index";
--- For IEC 61010-2-020.2006 references other international standards have been adopted as identical or modified our standards, this
Partially replaced with corresponding international standards of national standards or industry standards; the rest No equivalent or modify adopted as our standard
Quasi-international standards, are directly referenced in this section.
This section is GB 4793.7-2001 "measurement, control and laboratory centrifuge for special electrical safety laboratory equipment
Seeking ". Revision (IEC 61010-2-020 1992, IDT) is.
This section must be combined GB 4793.1 "measurement, control and laboratory use Part 1 safety requirements for electrical equipment. General Requirements"
Since use. Stated in this section "applicable" portion represents the corresponding strips GB 4793.1 apply to this section; this section states that "place" or
"Edit" section, to show that this part of the article subject; in this section indicate the "increase" portion, in addition to meeting indicate corresponding GB 4793.1
To section, this section must meet the increased strip. In order to distinguish the bar GB 4793.1, this part of the increase in the number of bars 101 open
Beginning, e.g. 3.1.101, this part of the increase in Appendix begin with AA, AA e.g. Appendices, Appendix BB.
This part of GB 4793.7-2001 have more major changes. many of the provisions in the text has been modified, with a standard structure
GB 4793.1-2007 were adjusted for a number of test methods to do a more detailed explanation.
--- Test Method rotating assembly of moving parts;
--- protection method of scattering or ejection of parts parts;
--- Test Method for preventing dangerous part of the fluid and the freezing of the water-cooled laboratory centrifuge;
--- dynamic seal microbiological testing methods.
Appendix AA in this section are normative, Appendix BB is an informative annex.
This section was proposed by China Machinery Industry Federation.
