1. I have a question about achieving ISO 17025 accreditation for a specific lab at fixed premises. Once you attain accreditation for a lab can you also expand the accreditation to another premises? Would the lab tests being performed in the new premises have to be re-validated etc?
2. Another question regarding calibration due dates. Is it ok to write a calibration due date on a calibration cert for a device we have calibrated? Do we need to write a disclaimer saying the calibration interval is determined by the customer? I've seen this on a number of ISO17025-accredited certificates.
3. One last question, we use a subfraction of an ISO 12103-1 standard dust for calibrating our dust monitors. Does this material need to be tested (particle distribution) by an ISO 17025 accredited laboratory? we have a particle distribution from a non-accredited lab for the material. I am concerned that as we are using it as a reference material we would need to have an accredited certificate of the particle distribution.
