NOTE Metering devices are not covered by this standard.
This European Standard does not deal with hazards caused by the processing of materials and which may lead to a risk of fire or release of health hazardous materials.
An extruder conforming to this document is not regarded as a pressure vessel as defined in the Pressure Equipment Directive 97/23/EC.
Extruders usually do not produce explosive atmospheres. Where materials are processed, which may cause an explosive atmosphere, the Directive 94/9/EC on the Equipment intended for use in Potentially Explosive Atmospheres (ATEX) should be applied.
