EUROLAB laboratory provides testing and compliance services within the scope of IEC 60068-2-13 standard. This part of the IEC 60068 standard specifies test methods applicable to specimens that may be exposed to low air pressure during transport, storage or service. The purpose of low air pressure testing is to determine the ability of components, equipment or other objects to be used, transported or stored at low air pressure.
Components, equipment or other objects to be used, transported or stored under the simultaneous combination of high or low temperature and low air pressure are subsequently tested as appropriate where the combination is significant for the voltages applied to the objects or for failure mechanisms.
The sample is given to the test chamber, then the chamber air pressure is reduced to the appropriate value specified in the relevant specification. These conditions are maintained for the specified period. The test chamber must be able to meet the given air pressure conditions. Care should be taken to avoid air contamination with ancillary equipment and devices, and with supplied air when pressure returns to normal.
When testing heat-dissipating samples, the relevant specification may require applicable requirements for the test chamber according to IEC 60068‑2‑2 test Bd or test Be.
It will be possible to maintain the air pressures specified in the relevant specification within the room with a tolerance of ±5% or ±0,1 kPa, whichever is greater. At 84 kPa, the tolerance will be ±2 kPa. At the start of the test and throughout the test, the test chamber must be within the required temperature range specified by the standard atmospheric conditions for testing according to IEC 60068-1.
The sample should be placed in the chamber in an orientation, configuration and operating condition as specified in the relevant specification. The pressure in the chamber should then be reduced to the value appropriate for the intensity. The relevant specification may limit the rate of pressure change to no more than 15 kPa/min if deemed necessary.
If required by the relevant specification, the sample should be operated and/or functioned in accordance with the procedures specified in the relevant specification. For heat dissipating samples, the relevant specification may require that the sample temperature be stabilized before any functional checks and/or measurements are made.
Intermediate measurements will be made if required by the relevant specification. Air pressure should be maintained for the specified time. Air pressure should be returned to normal. If required by the relevant specification, the air pressure change rate will not exceed 15 kPa/min.
The sample must remain under standard atmospheric conditions for not less than 1 hour and not more than 2 hours before final measurements, unless otherwise specified in the relevant specification.
