Introduction

Scope of application of the standard and technological evolution

This standard applies to smart bathroom equipment with a rated voltage of ≤250V, including 7 types of products such as smart toilets and flush seats. Compared with the 2002 version, the main changes are:

Version	Core changes	Scope of impact
2002 version	Basic safety requirements	Traditional electric toilets
2021 version	New software evaluation requirements	Smart products with program control
A12:2023	Application of test probe 19	Upgrade of anti-electric shock protection

Analysis of key safety requirements

Electrical safety

• Protection level: Toilet products must at least meet IPX4 waterproofing
• Leakage current: Bare heating element water heating equipment ≤0.25mA (test method see Figure 101)
• Insulation requirements: Excrement contact areas are designed according to pollution level 3

Mechanical safety

Case: The seat ring needs to pass the 21.103 clause test:

1. 1250N vertical force cycle test 20,000 times
2. 890N lateral force alternating test 10,000 times

Abnormal operation protection

Components	Normal temperature rise (℃)	Abnormal temperature rise (℃)
Human body contact surface	23	36(metal)/55(non-metal)
Drying hot air	40	65
Rinsing water temperature	≤45	≤65

New requirement 19.101: The risk of simultaneous startup of multiple heaters/motors due to program failure must be evaluated

Implementation recommendations

Design phase

• Metal supports should adopt Class II structure or be reliably grounded
• Vacuum toilets must implement a cover closing linkage mechanism (22.104)
• Rubber seals must pass a 100°C mineral oil immersion test

Certification preparation

1. Prepare a salt spray test report (IEC 60068-2-52)
2. Complete software evaluation documentation (Annex R)
3. Mark safety warning labels (Clause 7.101)

EU Compliance Guide

This standard meets the core requirements of the Low Voltage Directive 2014/35/EU, and establishes a corresponding relationship through Annex ZZA:

• Protection against electric shock: Clauses 8, 13, 16, and 27
• Mechanical hazards: Clauses 20 and 21
• Overheat protection: Clauses 11 and 19
