These include the Spanish Association for Standardisation and Certification (Aenor), the body devoted to standardisation and certification (S&C) of all industrial and service sectors; and, on an international level, the International Organisation for Standardisation, or ISO, which promotes international standards in manufacturing (for both products and services), commerce and communications for all industrial areas except electricity and electronics.
