Recommendations for renewable energy and hybrid systems for rural electrification - Laboratory evaluation of lamps and lighting appliances for off-grid electricity systems Ingestion-build-260237 850 nm or 1 3001 Scope This part of IEC 62257 establishes the framework for creating a product specification for lamps and lighting appliances to serve as the basis for evaluating quality for a particular context. Product specifications include minimum requirements for quality standards, warranty requirements, and or performance criteria. Products are compared to specifications based on test results and other information about the product. The product specification
