The science of appliance

摘要

paraBlack boxes are need to be tested for long life and robustness as service engineers are unlikely to be able to carry out repairs on site. The testing regime for black boxes is an integral part of the total appliance lifecycle test. Some electronic standards overlap and some are unique to the micro and software-based systems. In view of the costly, extensive and difficult testing of software and electronics, appliance manufacturers prefer to rely on the mechanical approach for safety critical systems. Electrolux Home Products maintains a design and research and development (RD) office for core technology and innovation in Pordenone, Italy. The company has in place design rules that predict the life of the component, backed up by a huge amount of statistical data. Vent-Asia on the other hand carries in-house functionality tests to ensure that each product is compliant with the Low Voltage Directive for safety, and the EMC (electro-magnetic compatibility) directive. Most testing is done with ASTA-BEAB third party approval./para
