Applies to proximity devices with an enhanced resistance to fault. Specifies requirements for four different types of PDF: PDF with desifned reliability; PDF with test capability, PDF with single fault tolerance and PDF with self-monitoring. This Standard is identical with and reproduced from IEC 60947-5-3:1999.

This part of IEC 60947 applies to proximity devices with an enhanced resistance to failure (PDF).It specifies requirements for four different types of PDF.NOTE – Due to their enhanced resistance to failure, PDFs apply for instance to:– interlocking devices (see ISO 14119);– the detection of the presence or absence of protective devices (see ISO/TR 12100-1).For a PDF used in applications where additional characteristics, dealt with in other standards, are required, it will be necessary to satisfy the requirements of all relevant standards.
