Low voltage switchboardsQuality inspection guide2010
ForewordOn the strength of its experience, Schneider Electric has always sought to produce hight-quality equipment, fully complying with IEC 60439-1 and IEC 61439-2 standards.
But what exactly do we mean by Quality?
The ISO 9000 standard defines quality as:the degree to which a set of inherent characteristics fulfils requirements.Although final inspection is in some respects a recognition of failure (as we have not been able to control the necessary quality throughout the assembly process), it is nevertheless a vital stage in equipment production.
This stage must be performed with care and rigour, in compliance both with customer specifications (explicit needs) and with proper operating procedures (implicit needs), in order to satisfy the customer.
Quality is also the determination of all the staff, from the manager to the line worker, to satisfy the customer. This guide is a good means to help you in this and to achieve excellence.
Thank you for your contribution.
