Explanatory notes

Standards DIN 13 Parts 16 to 18 give instructions relevant to the manufacturer and use of gauges for checking ISO metric screw threads with diameters of 1 mm and larger complying with DIN 13 Parts 1 to 10. Other methods of checking, for example measurement with indicating instruments, may be used, care being taken to ensure that the results achieved are the same as those obtained by using the gauges. The results of inspection using gauges complying with DIN 13 Parts 16 to 18 shall always be definitive. The purpose of these standards is to provide means of distinguishing between workpiece threads that comply with the limits of size and those that do not.
