The site documents and implements how often, how and by whom sieves, screens, filters and other foreign-matter detection or removal equipment are used, checked, maintained and calibrated (11.7.4.1). If the site uses detection or removal systems, it fixes detection limits based on assessing the risk posed by the product and its pack and detector locations identified (11.7.4.2); metal detectors and other detection technologies are routinely monitored, validated and verified and designed to isolate defective product and signal rejection (11.7.4.3). Records cover inspections of detection devices, products they reject or remove, and resulting corrective and preventive action (11.7.4.4). Any batch or item contaminated with foreign matter is set aside and then inspected, reworked or discarded, and the outcome recorded (11.7.4.5).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
