I'm struggling with this one in respect to ISO 9001:2015 188.8.131.52. We use a number of assembly fixtures that error proof our assembly process (preventing bowing in MDF cabinets while they're screwed together). Each product SKU has its own fixture. Do these fixtures constitute "monitoring and measuring resources"? Or, maybe fixtures fall more into 7.1.3 as "equipment" which has no requirement for documented information? Thanks!
