CHEKS AND TESTS IN ALL MANUFACTURING PHASES

Converters should undergo extensive routine and type tests in all important phases of the manufacturing process

Tests are performed according to the specifications of the customer and international standards

Comprehensive tests make sure that customers high demands for quality and reliability are fully met
