Classification of chemicals used at Atest-Gaz
Because of the need to present a
consistent and high level of maintenance services
, to ensure
the
safety of the calibration process
and to
create a basis for a rational calculation of the costs
of this process,
Atest-Gaz developed the "Classification of Chemical Substances" described below.
The classification determines the complexity of the calibration process of a particular detector type,
consider two criteria:
stability of the calibration mixture (criterion
A
):
•
ease of generate and its stability,
•
ergonomic complexity of operations,
•
required experience and knowledge of the employee performing the calibration,
•
required equipment,
•
environmental requirements for the process (e.g. weather conditions).
safety / potential hazard generated by the mixture (criterion
B
).
These both criteria have an impact on the final cost of the calibration services and level of competence
required from the employee conducting the calibration.
This classification is applied both by Atest-Gaz and the entities cooperating with it – distributors, authorized
service providers and users of the systems.
In the case of calibration with the "crossover" substances, the classification is made in accordance with the
substance category that is applied (e.g. for the detector with a PID sensor this substance is isobutylene, i.e.
B0 A0).
The detector are classified on the stage of offer.
On the next page we present tables showing the above relationships.
