8.2.2 Voltage variations
The EUT shall be tested for each of the specified voltage variations, three times at 1 0 s intervals in the most representative operating modes.
When requested, the EUT shall be tested with the gradual voltage variation representing the charging and discharging cycle of the batteries, the level and duration of this voltage variation being defined in the relevant product standard.
9 Evaluation of test results
The test results shall be classified in terms of the loss of function or degradation of perform-ance of the equipment under test, relative to a performance level defined by its manufacturer or the requester of the test, or agreed between the manufacturer and the purchaser of the product. The recommended classification is as follows:
a) normal performance within limits specified by the manufacturer, requester or purchaser;
b) temporary loss of function or degradation of performance which ceases after the disturbance ceases, and from which the equipment under test recovers its normal performance, without operator intervention;
c) temporary loss of function or degradation of performance, the correction of which requires operator intervention;
d) loss of function or degradation of performance which is not recoverable, owing to damage to hardware or software, or loss of data.
The manufacturer’s specification may define effects on the EUT which may be considered insignificant, and therefore acceptable.
This classification may be used as a guide in formulating performance criteria, by committees responsible for generic, product and product-family standards, or as a framework for the agreement on performance criteria between the manufacturer and the purchaser, for example where no suitable generic, product or product-family standard exists.
1 0 Test report
The test report shall contain all the information necessary to reproduce the test. In particular,the following shall be recorded:
– the items specified in the test plan required by clause 8 of this standard;
– identification of the EUT and any associated equipment, e.g. brand name, product type,serial number;
– identification of the test equipment, e.g. brand name, product type, serial number;
– any special environmental conditions in which the test was performed, e.g. shielded enclosure;
– any special conditions necessary to enable the test to be performed;
– performance level defined by the manufacturer, requester or purchaser;
– performance criterion specified in the generic, product or product-family standard;
– any effects on the EUT observed during or after the application of the test disturbance, and the duration for which these effects persist;
