Acoustical Standards
Ordering Calibration Services
If all the services you wish to order have a fixed fee, please use the Agreement for Standard INMS Calibration Services. Otherwise, you must request a quote from the technical contact providing the calibration service and a custom agreement will be provided.
DO NOT ship any equipment to NRC before sending a signed copy of the agreement to the technical contact. By email with electronic signature or by fax is acceptable.
The calibration costs quoted DO NOT include shipping, insurance or the cost of a customs broker. The client must arrange and pay for these services separately.

Loan of a calibrated portable NRC ultrasound power balance
Fee on request |
A calibrated portable NRC ultrasound power balance, which has a range of 10 W, is delivered to the client's address by courier service. The client may use the balance for two days before returning the balance to NRC by courier service. An additional $100 per day is added to the fee if the balance remains with the client for more than two days. The balance is calibrated upon return and the client notified in writing. |
A33-01-05-02
