Trapped Key Interlocks

In addition to ISO 9001: 2008 certification, Haake has introduced the Full Quality Assurance System (FQA) in accordance with the guidelines of Annex X of the Machine Directive 2006/42/EC. This system was subsequently certified by the Notified Body DGUV. It enables Haake to deliver every individual HST® system without further certification by a Notified Body. This is mandatory for safety components that are supplied individually and are not covered by harmonized European standards. In short: Where other trapped key interlock systems in the market still have to be individually certified by a Notified Body after delivery, the Haake HST® system immediately meets the required safety standard up to a maximum Performance Level 4 (PLd). This not only saves time, but also significant costs.
