3 Certificates
3.1 Class Type Approval
According to IACS UR‐Z17, the ultrasonic tightness testing equipment used by Class Service Suppliers for testing the
weathertight integrity of hatch covers should be class type approved.
Like its predecessor – the SDT Sherlog TA – both the Sherlog Kit Cadet (with SDT200 receiver) and Sherlog Kit Master
(with SDT270 receiver) have been developed in order to meet with Class criteria for Type Approval. Both equipments
have the necessary features on board to comply with, and exceed, Class type approval requirements. The high quality of
SDT equipment reassures ship owners and their managers that their ships have been inspected with state of the art
equipment that meets with the highest industry standards.
3.2 The calibration certificate
SDT recommends annual recalibration of SDT instruments and sensors. This periodicity is coherent with the observed
long‐term stability of SDT electronic equipment’s.
However
-
The first SDT certificate is valid for a period of 15 months (to avoid penalizing a customer receiving an instrument
that stayed in stock for 3 months).
-
SDT recognizes that each customer may have their own Quality Assurance Standards and internal requirements.
If a customer has established a Quality Assurance Program that includes a documented procedure for
measurement deviations, and if an instrument and the relevant sensor show acceptable deviations and do not
show signs of physical damage, then calibration periodicity could be extended to two years.
-
Third party organizations having more authority (Class, or State Administrations) may have defined their own
regulations for example 6 months, or 2 years calibration interval: by evidence, local legally applicable regulations
supersede SDT rules.
For these reasons, SDT Calibration Certificates do no more mention a “calibration due date”, but simply the “last
calibration date”.
For user convenience, the date of the last calibration of an SDT200 or 270 instruments can also be found in the menu
screens.

3.3 The certificate of qualification
A certificate of qualification is obtained after having successfully passed the theoretical and practical on‐ board training
program. The validity of the certificate is limited to three years. A copy of the Calibration Certificate is available in the
Appendixes section.
