Immunity against radiated high frequency disturbances

    Testing of the immunity of a VAS/AS/immobiliser in a vehicle may be performed according to one of the methods described in the International Standard ISO 11451 - 1 through 4-1993, or laboratory testing may be performed according to one of the methods described in the International Standard ISO 11452 - 1 through 7-1993.

    Test severity level II shall be applied.  The functional status A shall be maintained during and after the test.  For values of severity level see relevant part of the International Standards ISO 11451-1993 and 11452-1993.  A description of the functional status is given in part 1 of both standards.

Electrical disturbance from electrostatic discharges

    Immunity against electrical disturbances shall be tested in accordance with ISO/TR (Technical Report) 10605-1993.

Radio frequency interference (RFI) suppression

Tests according to the relevant clause of CISPR 12-1990.

2. ACCORDING TO THE IEC METHOD

Electromagnetic field

    The VAS/AS/immobiliser shall undergo the basic test.   It shall be subjected to the electromagnetic field test described in IEC Publication 839-1-3-1988 test A-13 with a frequency range extended to 1000 MHz and 50 V per m.

And

    The VAS/AS/immobiliser shall be subjected to the electrical transient conducted and coupled tests described in the International Standard ISO 7637

Parts 1-1990 and 3-1993 as appropriate.

Immunity against radiated high frequency disturbances

    The VAS/AS/immobiliser shall be subjected to testing for immunity against radiated high frequency disturbances as described in the International Standard ISO 11452-1993 Parts 1 to 7 as appropriate.
    Electrical disturbance from electrostatic discharges

    The VAS/AS/immobiliser shall undergo the basic test.  It shall be subjected to the electrostatic discharge test described in IEC Publication 839-1-3-1988 test A-11 (severity 3).

Or

    The VAS/AS/immobiliser shall be subjected to testing for immunity against electrostatic discharge as described in ISO TR (technical report) 10 605-1993.

Radio frequency interference (RFI) suppression

    The VAS/AS/immobiliser shall be subjected to testing for the suppression of radio frequency interference according to tests prescribed in the relevant clauses of CISPR12-1990.

Electrical spikes

    The VAS/AS/immobiliser shall undergo the basic test.  It shall be subjected to the electrical spikes as described in IEC Publication 839-1-3-1988 test A-9 (severity 4).
