In the context of increasingly high requirements for the quality and quietness of household appliances, especially products such as refrigerators, material testing acoustics – refrigerator noise measurement and certification of noise levels according to international standards become an indispensable step in the product evaluation process.
At the DASM Institute of Acoustics Materials Application and Development, we provide refrigerator noise measurement services in accordance with ISO 7779:2018 and within standard-compliant laboratory environments of ISO 3745:2012, comprehensively supporting manufacturers and contractors in product development, certification, and export.
Introduction to ISO 7779:2018 and ISO 3745:2012
ISO 7779:2018 is an international standard specifying methods for measuring noise levels emitted by information technology (IT) equipment, refrigeration equipment, and household appliances during operation.
Meanwhile, ISO 3745:2012 specifies requirements for anechoic chambers and procedures for determining overall sound pressure levels in measurement environments.
These standards are applied globally and play a crucial role in determining noise classification, improving performance, and enhancing user experience.
Benefits of ISO-compliant refrigerator noise measurement for manufacturers and contractors
Measuring noise levels and refrigerator noise according to ISO standards brings practical benefits:
+ Product quality certification: Helps affirm that the product meets international market noise requirements, increasing competitiveness when exporting or participating in projects.
+ R&D support: Serves the research and development process of new products, optimizing performance and noise levels.
+ Conformity/compliance certification: Supplements the conformity certification dossier for domestic circulation or export equipment.
+ Improving user experience: Products that are quiet, not too noisy, and more stable are key factors consumers care about when choosing.
