Does the requirement for traceability only apply to physical quantities?


No. The requirement for metrological traceability applies to all quantities (chemical, biological, etc.). Establishing the traceability of measurements is clearly more complex in these fields than in conventional fields, such as the metrology of mass. But the fact that it is more difficult does not mean that it can be ignored.
