EMS performance criterion

Performance criterion A:

Without operator intervention, the equipment should be able to continue to work as expected. When the equipment is used as intended, no performance degradation or loss of function below the performance level specified by the manufacturer is allowed. The performance level can be replaced with an allowable performance reduction. If the manufacturer does not stipulate the minimum performance level and allowable performance reduction, it can be known from the product specification or technical documentation, and the user has reason to require the equipment used to meet this requirement.

Performance criterion B:

After the start of the test, without the need for operator intervention, the equipment should continue to work as expected. When the equipment is used as expected, after the harassment is applied, no performance degradation or loss of function below the manufacturer's specifications is allowed. The performance level can be replaced with an allowable performance reduction. During the test, performance degradation is allowed. However, after the test, the working state should not change and the stored data should not be lost. If the manufacturer does not stipulate the minimum performance level and allowable performance reduction, it can be known from the product specification or technical documentation, and the user has reason to require the equipment used to meet this requirement.

Performance criterion C:

The loss of function that can be recovered by itself or can be restored by the user according to the manufacturer's instructions is allowed.

Functions and / or information stored in non-volatile memory or protected by a backup battery should not be lost.
