Overview
EN 60456:2016 (CLC adoption of IEC 60456:2010, modified) defines standardized methods for measuring the performance of household clothes washing machines, including washer‑dryers and spin extractors. The standard covers machines with or without internal heating that use cold and/or hot water, and includes provisions for machines that specify “no detergent” for normal use. EN 60456:2016 is the harmonized test basis used for product evaluation, energy labelling and ecodesign compliance in Europe.
Key Topics and Requirements
- Performance measurements: standardized procedures to evaluate washing performance, rinsing efficiency, water extraction (spin), remaining moisture content and programme times.
- Energy & water consumption: methods to measure consumption per programme and annualized metrics (AE/SAE), including low power modes such as “OFF” and “Left On”.
- Test loads and preparation: specifications for conditioned test loads, detergent use, folding and loading procedures tailored to vertical/horizontal/twin‑tub systems (Annex H).
- Reference machine & programmes: use of reference machine specifications and new reference programmes for lower temperatures and vertical axis systems (Annex D).
- Stain testing: defined stain/soil sets and standardized stain test strips for objective washing performance evaluation (Annex A).
- Instrumentation and accuracy: requirements for measurement instruments, ambient water/electricity supply conditions and accuracy (Clause 5).
- Uncertainty and tolerances: guidance on measurement uncertainty and control procedures (new annex on uncertainty; Annex ZB).
- Combined test sequences: procedures for full and partial load combined test series supporting energy label and ecodesign assessment (Annex ZA, ZZA, ZZB).
- Informative procedures: additional guidance for manual washing machines, test load sizing where rated capacity isn’t declared, and left‑on mode energy measurement (Annices M, N, L).
Practical Applications - Who Uses It
- Appliance manufacturers: to verify performance data, declare rated values and demonstrate compliance with EU energy‑labelling and ecodesign rules.
- Test laboratories and conformity assessors: to perform repeatable, comparable performance and energy tests.
- Regulators and market surveillance: to check declared values and apply tolerances/control procedures.
- R&D and QA teams: for product development, benchmarking and validating new wash programmes or low‑temperature cycles.

The introduction of soft water options enhances the relevance of the standard in diverse geographical markets where water quality may vary. Additionally, the standard has improved procedures for loading and folding test items, ensuring that performance assessments accurately represent real-world usage for vertical axis, horizontal axis, and twin tub washing systems. This detail underscores the standard's adaptability and its commitment to delivering relevant and reliable performance metrics. Significantly, EN 60456:2016 has expanded its stain and soil set parameters, reflecting advancements in textile technology and consumer needs. The revision of reference machine specifications to incorporate the Electrolux Wascator CLS is a forward-thinking approach that ensures the standard remains up-to-date with innovations in washing machine technology. The inclusion of new reference programmes for lower temperature and vertical axis systems responds to the increasing consumer demand for energy-efficient and environmentally friendly washing solutions. Furthermore, the refined rinsing efficiency method demonstrates a commitment to improving wash outcomes while minimizing water usage, aligning with sustainability goals. The introduction of low power modes such as "OFF" and "Left On" is another notable advancement, addressing energy efficiency in household appliances. This aligns the standard with modern concerns about energy consumption and encourages manufacturers to develop machines that are not only effective in cleaning but also considerate of energy use. Finally, the addition of an annex on measurement uncertainty provides greater transparency and reliability in the performance data derived from the testing processes outlined in the standard. This level of rigor enhances the standard’s authority and trust among manufacturers, consumers, and regulatory bodies alike. In summary, EN 60456:2016 stands as a critical document in the field of household appliance standards, offering robust methodologies for evaluating washing machine performance, incorporating adaptable practices for various technologies, and remaining relevant to both consumer needs and environmental challenges.

SIST EN 60456:2016 표준은 가정용 세탁기 성능 측정을 위한 방법을 규정하고 있으며, 이 문서는 세탁기 테스트의 기준을 체계적으로 제시하고 있습니다. 이 표준의 범위는 세탁기에서 사용하는 냉수 및 온수 공급 장치를 포함하며, 세탁 및 건조 기능을 모두 가진 세탁기와 원심력에 의한 물 추출 장비인 스핀 익스트랙터에도 적용됩니다. 또한, 일반적인 사용 시 세제로 세탁하지 않는 세탁기에 대해서도 다루고 있어 다양한 사용 환경을 아우르는 중요성을 지니고 있습니다. 이 표준의 강점은 다양한 테스트 항목의 개선을 반영하여 보다 정확하고 신뢰할 수 있는 성능 평가를 가능하게 한다는 점입니다. 새롭게 수정된 시험 하중 질량Requirements는 테스트 기계의 정격 용량이 명시되지 않은 경우에도 적용될 수 있도록 했으며, 소프트 워터 옵션의 도입과 오염 세트의 확대는 실제 세탁 환경을 더욱 충실히 반영합니다. 또한, 세탁물의 적재 방법을 개선하여 수직 축, 수평 축 및 쌍둥이 통 시스템에 보다 적합하도록 설정한 것이 눈에 띕니다. 이 표준은 또한 저온 및 수직 축 시스템을 위한 새로운 기준 프로그램을 도입하고, 세척 효율성 평가 방법을 세밀하게 조정했습니다. 저전력 모드 "OFF"와 "LEFT ON"의 도입은 에너지 절약 측면에서도 중요한 개선 사항입니다. 새로운 부록에서는 측정의 불확실성에 대한 내용을 다루어, 테스트 결과의 신뢰성을 한층 높이는 기여를 합니다. 따라서 SIST EN 60456:2016 표준은 가정용 세탁기의 성능을 측정하는 데 있어 필수적인 지침을 제공하며, 다양한 세탁기 모델의 평가를 위한 근거로서 중요한 역할을 합니다. 이 표준에 따라 기술된 겨울, 여름, 세탁기 및 건조기 관련 기능은 모든 사용자에게 실질적인 도움이 될 것입니다.
