Foreword
The entire technical content of this section is mandatory.
GB 4793 "Safety requirements for electrical equipment for measurement, control, and laboratory use" is currently divided into 7 parts.
--- Part 1. General requirements (IEC 61010-1);
--- Part 2. Particular requirements for hand-held and hand-operated current sensors for electrical measurement and testing (IEC 6110-2-0232);
--- Part 3. Particular requirements for laboratory mixing and stirring equipment (IEC 61010-2-0051);
--- Part 4. Special requirements for autoclaves for medical materials used in laboratories (IEC 6110-2-0241);
--- Part 5. Safety requirements for hand-held probe assemblies for electrical measurement and testing (IEC 6110-1031);
--- Part 6. Special requirements for laboratory material heating equipment (IEC 6110-2-0-10);
--- Part 7. Special requirements for laboratory centrifuges (IEC 6110-2-20).
Note. The names of the above parts will change as the IEC standard names change.
This part is Part 6 of GB 4793.
This part is equivalent to adopting IEC 6110-2-0-10..2005 "Safety requirements for electrical equipment for measurement, control and laboratory use-Part 2-10
Sub-Special Requirements for Laboratory Heating Equipment (English version). Its technical content, text structure, and expression are in accordance with IEC 6110-
2-10..2005 is completely equivalent.
For ease of use, the following editorial changes have been made in this section.
--- Replace the comma "," with a decimal point "." As a decimal point;
--- Omit the content of the preamble of IEC 6110-2-0-10..2005;
--- For other international standards referenced in IEC 6110-10-2-10..2005, which are equivalent or modified and adopted as our national standards, this
Some of our national standards or industry standards replace the corresponding international standards; the rest are not equivalent or modified and adopted as our national standards
Standard international standards are directly cited in this section.
This section is for GB 4793.6-2001 "Safety laboratory material heating equipment for measurement, control and laboratory electrical equipment
"Special Requirements" (IEC 6110-2-10..1992, IDT).
This section must be combined with GB 4793.1 "Safety requirements for electrical equipment for measurement, control and laboratory use-Part 1. General requirements"
Use. The part that says "applicable" in this part means that the corresponding clause of GB 47.93.1 applies to this part; this part says "replaces" or
The "modified" part indicates that the provisions of this part shall prevail; the part that is marked with "added" in this part indicates that the division shall comply with the corresponding requirements of GB 47393.1.
In addition to the article, the article added in this section must also be met. In order to distinguish the bars in GB 47.93.1, the numbers of the bars added in this section start with 101.
Start, such as 5.2.1101.
Compared with GB 4973.6-2001, this section has major changes. Many clauses have been modified in text. The standard structure follows
GB 4793.1-2007 was adjusted, and some test methods were explained in more detail.
--- Increased the dynamic test of the horizontal heating surface of glass or ceramic materials;
--- Increased surface temperature limits for burn prevention.
