IEC 60335-2-84:2019

Overview

IEC 60335-2-84:2019 is the IEC product-family safety standard that specifies particular requirements for electric toilet appliances (rated voltage ≤ 250 V). It is Part 2-84 of the IEC 60335 series and is intended to be used together with IEC 60335-1 (general requirements). The 2019 third edition is a technical revision that updates definitions, installation instruction requirements, normative notes, and adds requirements for appliances with programmable electronic circuits.

Keywords: IEC 60335-2-84, toilet appliances, electrical safety, household appliances, spray seats, heated seats

What the standard covers

• Scope: Electric toilets and associated equipment where excrement is stored, dried or destructed, or appliances that wash/dry parts of the human body. Rated voltage not more than 250 V.
• Appliance examples: mouldering toilets, package toilets, freezing toilets, vacuum toilets.
• Equipment for conventional toilets: automatic seat covering devices, hopping units, heated seats, pumping units, water heaters for spray seats, spray seats.
• Excluded: chemical toilets; toilets where excrement is destructed by combustion; appliances for corrosive or explosive atmospheres.
• Hazards addressed: electrical, mechanical, thermal, fire, radiation and related hazards in normal and expected abnormal operation.

Key technical topics and requirements

• Mandatory conjunction with IEC 60335-1: Part 2-84 supplements or modifies Part 1 clauses as required.
• Marking and instructions: Updated requirements for installation instructions and possible appliance labeling options.
• Construction and components: Requirements covering protection against access to live parts, internal wiring, earthing, terminals, clearances/creepage and resistance to heat, fire and corrosion.
• Electrical tests: Leakage current and dielectric strength tests at operating temperature, transient overvoltage considerations and moisture resistance.
• Temperature limits and endurance: Normal and abnormal temperature rise limits and endurance testing.
• Software and electronics: New requirements (including Annex R) for programmable electronic circuits that limit concurrent heating elements and motors.
• Special national/regulatory considerations: Additional requirements may be required for vehicle, ship or aircraft installations or by national health/water/labour authorities.

Practical applications - who uses this standard

• Manufacturers and product designers of electric toilets, spray seats, heated seats, water heaters and related toilet equipment.
• Certification bodies and test laboratories performing safety compliance testing and type approval.
• Compliance engineers, regulatory authorities and purchasing/specification teams who need to ensure products meet international safety norms.
• Software/firmware engineers implementing safety-limiting programmable circuits referenced by Annex R.

Related standards

• IEC 60335-1 (Household and similar electrical appliances - Safety - General requirements) - mandatory companion.
• IEC 60364 (national wiring rules referenced in the introduction) and other IEC 60335 series parts when multiple appliance functions overlap.

This standard is a key reference for ensuring safe design, testing and certification of electrically powered toilet appliances and their components in household and similar environments.
