ISO/IEC 17025:2017 Decision Rule:

When a customer requests a statement of conformity to a specification or standard for the test calibration, ILT's simple accept decision rule shall apply:

When making a statement of compliance (in tolerance / out of tolerance), we base strictly on established tolerance with no accountability, unless otherwise agreed upon prior to calibration.

ILT requires all customers complete an online RMA request form prior to shipping goods to ILT for service.  Goods arriving without an RMA will require a hard copy PO or written confirmation prior to commencing service.  Submitting an RMA form, purchase order or written order confirmation will be considered as acceptance of ILT's Decision Rule as is designated, unless otherwise agreed to in writing prior to the start of calibration.
