IEC 60335-1 Household Appliance Safety Testing Overview
This IEC 60335-1 test equipment guide helps household appliance manufacturers, certification teams, CBTL laboratories
and procurement engineers identify typical instruments, fixtures and materials used for safety testing of household
and similar electrical appliances.
KingPo structures this page as a practical clause-based equipment selection guide. The checklist maps IEC 60335-1:2020
and IEC 60335-1:2020/AMD1:2025 test items to required testing and measuring equipment, with a reserved column for
recommended KingPo equipment categories and future product anchors.
This page is an equipment selection framework and website navigation guide. It is not a replacement for the official
IEC 60335-1 standard or IECEE documentation. Final compliance decisions should be based on official publications and
certification body requirements.
As of now, not all available test equipment and customized configurations are listed on our website.

Engineering Selection Tips by KingPo for IEC 60335-1 Test Equipment
IEC 60335-1 test equipment selection should begin with the basic safety tests that apply to most household appliance
laboratories: access to live parts, power input and current, heating, leakage current, electric strength, abnormal
operation, mechanical strength, supply cord tests, earthing, creepage and clearance verification, and resistance to heat
and fire.
KingPo recommends planning IEC 60335-1 equipment as a modular laboratory system instead of isolated instruments.
A complete setup normally combines electrical safety testers, thermal measurement systems, mechanical fixtures, IP test
equipment, material fire test apparatus and appliance-specific fixtures required by the relevant IEC 60335-2 particular standard.
A common procurement mistake is buying the general IEC 60335-1 instruments without checking the applicable Part 2 standard.
For example, liquid heating appliances, personal care appliances, cooking appliances and battery-operated appliances may
require additional fixtures, endurance systems or abnormal-operation configurations beyond the general Part 1 checklist.

FAQ: IEC 60335-1 Test Equipment
What is IEC 60335-1 test equipment used for?
IEC 60335-1 test equipment is used for safety evaluation of household and similar electrical appliances. Typical tests
include access to live parts, power input, heating, leakage current, electric strength, moisture resistance, abnormal
operation, mechanical strength, supply cord testing, earthing and resistance to heat and fire.
How should a laboratory select IEC 60335-1 test equipment?
Laboratories should first define the appliance category, rated supply, applicable IEC 60335-2 particular standard, test
volume and automation needs. KingPo can help map the general IEC 60335-1 checklist to appliance-specific fixtures and
complete laboratory configurations.
Is IEC 60335-1 enough for appliance certification testing?
IEC 60335-1 provides general safety requirements, but most household appliances also require the relevant IEC 60335-2
particular standard. Equipment selection should therefore include both general Part 1 instruments and appliance-specific
test fixtures from the applicable Part 2 standard.
What equipment is required for leakage current and electric strength tests?
The typical setup includes metal foil, a leakage current meter or low-impedance ammeter, isolation transformer, high
voltage tester and measuring network where required. The exact configuration should follow the applicable clause and
certification body interpretation.
What test equipment is used for resistance to heat and fire?
Resistance to heat and fire tests may require a ball pressure test apparatus, glow-wire test apparatus, needle flame test
apparatus, low-power circuit determination apparatus and, where applicable, horizontal and vertical burning test equipment.
Can KingPo provide a complete IEC 60335 household appliance test setup?
Yes. KingPo supports clause-based equipment planning for IEC 60335-1 and related IEC 60335-2 appliance standards,
including electrical safety instruments, environmental chambers, mechanical fixtures, fire test apparatus and customized
appliance endurance test systems.
Need Help Building an IEC 60335-1 Household Appliance Test Equipment Setup?
