Product Overview
IEC 61010-2-012 contains particular safety requirements for equipment used for climatic and environmental testing and other forms of temperature conditioning. Its scope includes equipment in which refrigerating systems, heating functions or other environmental-conditioning functions can introduce additional hazards. The standard is intended to be used together with IEC 61010-1.
The KP-ST10 IEC 61010-2-012 Figure 103 Scratching Tool provides the mechanical scratching tip required for the applicable scratch-test procedure.
This is not a general-purpose coating scratch tester or a measurement instrument for determining scratch resistance. Its purpose is more specific: it provides a defined scratching tool for use where the IEC 61010-2-012 test procedure requires an applicable surface to be scratched before the subsequent safety assessment.
The scratching tool therefore represents one component of the overall compliance test setup. Use of the KP-ST10 alone does not demonstrate conformity with the complete IEC 61010-2-012 standard.
What Does the Scratching Tool Test?
The KP-ST10 is used to create scratches on applicable surfaces specified by the relevant IEC 61010-2-012 test procedure.
In refrigerating-system safety evaluation, scratching is used to assess surfaces that may be exposed to foreseeable mechanical damage. Related IEC 61010 refrigerating-equipment requirements use scratch testing on accessible surfaces of protected cooling systems, followed where applicable by further pressure evaluation.
For IEC 61010-2-012 projects, the exact:
- surface to be scratched,
- number and location of scratches,
- applied test conditions,
- subsequent test procedure, and
- acceptance criteria
should always be determined from the applicable edition and clause of the standard for the equipment under test.

IEC 61010-2-012 and the Figure 103 Requirement
IEC 61010-2-012:2019 is titled “Safety requirements for electrical equipment for measurement, control, and laboratory use – Part 2-012: Particular requirements for climatic and environmental testing and other temperature conditioning equipment.” Figure 103 in this standard is identified as the figure showing the details of the scratching tool tip.
IEC explains that Part 2-012 specifically addresses hazards associated with equipment where heating and refrigerating systems interact in a manner that can create additional or more severe hazards. It can also apply to certain equipment involving other environmental-conditioning factors.
This distinction matters when selecting the test tool because the IEC 61010 series contains different Part 2 standards for different equipment architectures.
How the Scratching Tool Is Used
A typical laboratory workflow is:
Figure 103 Tool Construction
Hard-Soldered K10 Carbide Tip
The KP-ST10 uses a hard-soldered K10 carbide tip. This is the principal working element that contacts the test surface during scratching. The source product specification identifies K10 carbide as the tip material.
Surface Roughness
The specified surface roughness is:
This value is retained from the original KP-ST10 technical information and should be treated as a tool specification rather than as a DUT acceptance criterion.
Figure 103 Geometry
The product is referenced to IEC 61010-2-012 Figure 103, which defines the details of the scratching tool tip.
Where dimensional inspection data are required for an accredited laboratory or certification project, the required drawing dimensions and verification documentation should be confirmed before quotation.
Typical Test Objects
Depending on the equipment design and applicable clause, the Figure 103 scratching tool may be relevant when evaluating accessible surfaces associated with refrigerating systems in equipment within the scope of IEC 61010-2-012.
Typical equipment categories covered by the standard can include:
Who Uses the KP-ST10 Scratching Tool?
The KP-ST10 is suitable for organizations performing controlled product-safety evaluation, including:
For these users, the main purchasing requirement is not simply carbide hardness. It is confirmation that the supplied tool corresponds to the applicable standard, edition and Figure 103 test requirement.
Engineering Notes
Compliance & Regulatory Assurance
- The KP-ST10 Scratching Tool is designed for scratching-tool applications associated with IEC 61010-2-012 Figure 103, supporting standard-oriented laboratory and certification testing where the applicable edition, clause and test procedure have been confirmed.
- Final suitability should be confirmed against the applicable standard edition and test procedure. Inspection or material documentation can be provided according to the confirmed configuration.
Technical Inquiry & Expert Support
To confirm whether KingPo KP-ST10 is appropriate for your test project, please provide:
- Applicable standard: IEC 61010-2-012 or other standard
- Standard edition: if specified by the project
- Clause / Figure: Figure 103 and the applicable test clause, if known
- Equipment under test: climatic chamber, environmental test equipment, temperature-conditioning equipment or other EUT
- Refrigerating-system configuration: where relevant to the test
- Required documentation: dimensional report, material information, calibration or accredited laboratory documentation
