KINGPO Standard Test Equipment Guide
IEC 60335-1 defines general safety requirements for household and similar electrical appliances. Testing laboratories use a combination of measurement instruments, access probes, mechanical fixtures, electrical safety equipment, environmental systems and fire-test apparatus to evaluate the relevant requirements.
This guide organizes the principal equipment and materials associated with IEC 60335-1 clauses and annexes, then connects them to relevant KINGPO product pages and categories. It also covers supporting instruments, accessories and appliance-specific fixtures that may be required by the applicable Part 2 standard.
Scope note: The reference file supplied for this guide is titled as an interim IECEE equipment list. This guide supports equipment selection but does not replace the official IEC publication or the certification body’s current requirements. Confirm the currently accepted list, applicable edition, Part 2 standard, test method and laboratory scope before final selection.

Additional and Appliance-Specific Equipment
These quotation-derived items are separated from the core IECEE checklist. Where the source list does not specify a subclause, the table does not invent one. Part 2 and related-standard equipment is identified by its own standard.
Important distinction: A related test method or accessory is not automatically a universal IEC 60335-1 requirement. For example, dust ingress testing is separate from Clause 15 moisture resistance, and a tumbling barrel is not a substitute for the specified free-fall apparatus.

Engineering Selection Tips for IEC 60335-1 Test Equipment
Start with the appliance type and the exact clause or figure to be tested. IEC 60335-1 sets general requirements, while the relevant IEC 60335-2 standard can add, replace or modify test conditions. A fixture that looks similar may not have the required probe geometry, force range, cycle profile, temperature capability or measurement input characteristics.
Before procurement, confirm the standard edition, test clause, specimen dimensions, rated voltage/current, required force or torque, temperature and humidity conditions, test duration, fixture geometry, data recording needs and calibration documentation. For battery-operated products, also review the battery chemistry, state-of-charge requirements, shorting resistance, pressure/air delivery setup and safety containment.
For tests marked as subcontractable or requiring a specialized facility, the laboratory should confirm whether the work will be performed in-house or through an accepted external laboratory. The selection should follow the certification programme and the laboratory’s intended accreditation scope.

FAQ: IEC 60335-1 Test Equipment
What equipment is needed for IEC 60335-1 testing?
The required setup depends on the clauses being evaluated and the appliance type. Common categories include electrical measurement instruments, access probes, temperature measurement equipment, moisture-resistance systems, mechanical fixtures, torque tools and heat/fire test apparatus. The relevant Part 2 may add product-specific requirements.
Does every laboratory need all equipment listed on this page?
No. IECEE equipment classifications distinguish equipment that is required, may be subcontracted or needs a specialized facility. The final list should match the laboratory’s test scope and certification programme.
What is the difference between IEC 60335-1 and IEC 60335-2?
IEC 60335-1 provides general safety requirements for household and similar electrical appliances. The relevant IEC 60335-2 standard addresses a particular appliance type and may specify additional or modified tests.
Is an IP5X/IP6X dust chamber part of Clause 15 moisture-resistance testing?
No. IP5X/IP6X dust ingress testing is a separate method under IEC 60529 and may be required by an applicable product standard. It should not be presented as the same test as Clause 15 moisture resistance.
How does a tumbling barrel relate to free-fall testing?
A tumbling barrel can be used for repeated free-fall testing when the specified procedure calls for it. The quotation cites IEC 60068-2-32:1975, which has been withdrawn and replaced by IEC 60068-2-31:2008. Confirm the applicable procedure and appliance-specific requirements before selecting the apparatus.
Can KINGPO help configure a complete test setup?
Yes. KINGPO can help laboratories and manufacturers identify the relevant equipment, accessories and fixture configurations based on the appliance type, standard edition, clause, test ranges and laboratory requirements.
Need Help Selecting IEC 60335-1 Test Equipment?
Share the appliance type, applicable IEC 60335-2 standard, clause numbers and required test capabilities. KINGPO can help identify the relevant instruments, fixtures, accessories and configuration options for your laboratory.
