IEC 60436:2025

Overview

IEC 60436:2025 is the fifth edition of the International Standard by the International Electrotechnical Commission (IEC) addressing performance measurement methods for electric dishwashers for household use. This standard applies to dishwashers supplied with hot and/or cold water, including free-standing, built-in, integrated, and multi-compartment models. The document defines principal performance characteristics and elaborates on standardized test methods to assess these key features. Importantly, the standard focuses solely on performance measurement and does not cover safety or minimum performance requirements.

Updated in 2025, IEC 60436 replaces the 2015 edition and the 2020 amendment, introducing a range of technical revisions aimed at reflecting modern dishwasher technologies and market formulations.

Key Topics

• Reference Machine and Detergent: Introduction of a new reference machine better suited to evaluate energy and water-saving innovations in modern dishwashers. The standard also updates to a new reference detergent type E that includes upgraded enzymes and a lower silicate content to reduce alkalinity, easing global transportation and usage.

• Cleaning Performance Alignment: A scientific alignment factor has been implemented to correlate previous cleaning performance test results with those obtained using the updated reference system.

• Component Replacements: New replacements for key soiling components like pans and knives have been introduced due to discontinuation of previous models.

• Temperature Control Enhancements: Room temperature measurement is now conducted inside the dishwasher just prior to test start for improved accuracy.

• Load Weight Updates: The weight of load items has been revised and specified ranges adjusted to better reflect actual tableware weights.

• Low Power Mode Testing: An updated, stepwise method for evaluating low power consumption modes, including network standby, has been developed. This addresses the energy profile of dishwashers with internet-connected smart features.

• Unit Variation Assessment: A new approach allows testing of multiple dishwasher units from the same model to better understand performance variations.

• Loading and Handling Instructions: New requirements provide clearer guidance for test institutes to standardize loading and handling during testing.

• Multi-Compartment Dishwashers: Specific testing methodologies for dishwashers with multiple compartments have been incorporated.

• Soil Preparation Process: Improvements to the ballast soil preparation process ensure consistent soiling used in cleaning tests.

Applications

IEC 60436:2025 serves as an essential framework for a variety of stakeholders in the dishwasher industry:

• Manufacturers can use this standard to benchmark dishwasher models, guide product design improvements, and verify performance claims related to cleaning efficacy, energy use, water consumption, and drying efficiency.

• Testing Laboratories benefit from detailed instructions on test load preparation, standardized test sequences, and methodology to guarantee reproducible and valid performance measurements according to international best practices.

• Certification Bodies utilize these methods to evaluate compliance with performance declarations, enabling consistent labeling and consumer information.

• Energy and Environmental Regulators leverage standard measurement methods when defining energy efficiency regulations and water usage guidelines for household dishwashers.

Additionally, the update supports the industry’s move towards smart appliances by including procedures to assess power consumption in network-connected low power modes and account for real-world variations across units.

Related Standards

IEC 60436:2025 aligns with and complements several other IEC standards and international norms within the electrotechnical and household appliance sectors:

• IEC 60335-2-5 - Safety requirements for dishwashers, addressing safety rather than performance.

• ISO 14040 Series - Environmental management standards related to life cycle assessment, useful when considering energy and water consumption impacts of dishwasher use.

• Energy labeling regulations (regional) - Standards adopted by various regions for energy efficiency labeling, which often reference performance test methods like IEC 60436.

• Testing protocols for connected appliances - Emerging standards focusing on measuring and monitoring energy consumption in network-integrated household appliances.

By adhering to IEC 60436:2025, manufacturers and laboratories ensure harmonized, accurate, and reproducible measurement of electric dishwasher performance globally, supporting innovation, consumer confidence, and regulatory compliance in the rapidly evolving home appliance market.
