laboratory simulation, usually severe, of the climatic, mechanical, biological, electrical (including electrostatic) and chemical environmental influences acting on the specimen during assembly, storage,transport and operation, in order to establish any changes in the behaviour of the specimen in a short time
instrument whose function is mainly based on optical phenomena, consisting of several assemblies and/or components, ilumination systems, instruments with light conduction and instruments which,apart from optical units, contain assemblies and/or components from other fields
EXAMPLE Electronic components.
sum of the external influences acting on the specimen during the test, such as the conditioning method and degree of severity employed, and of the internal influences resulting from the state of operation of the specimen, such as movements and/or temperature changes
individual or combined environmental influences to which the specimen is submitted during the test
EXAMPLE Shock or damp heat.
parameter containing all the individual quantities required for the test
EXAMPLE Temperature, humidity, conditioning time.
Note 1 to entry: Conditioning time (exposure time) is the minimum time if no tolerance is indicated in the relevant parts of ISO 9022.
state defining the operating status of the specimen during conditioning
Note 1 to entry: Three states of operation are distinguished: state of operation 0, state of operation 1 and state of operation 2.
Unless the relevant part of ISO 9022 or the relevant specification gives different directions for the test sequence, the test shall be performed in accordance with 3.2 to 3.8. Preconditioning, recovery, initial and final tests shall be carried out in as constant ambient atmospheric conditions as possible.
Preconditioning brings the specimen into the state necessary for initial testing and conditioning,e.g. cleaning of the exterior of the specimen, drying of the interior of the specimen, changing of the desiccator cartridges, or greasing of the areas liable to corrosion. The temperature of the specimen shall be adjusted to the ambient temperature to within 3 K.
After preconditioning, an examination shall be performed according to the relevant specification. This shall include a visual examination for damage, such as scratches on optical parts or cracks in other materials, which might influence the behaviour of the specimen.
After the initial test, the specimen shall be submitted to the conditioning method at the defined degree of severity and the state of operation given in the relevant specification.ISO 9022-1 pdf free download.
