ANNEX 6

Operation parameters and test conditions for an immobilizer

1. Operation parameters

The requirements below do not apply to:

(a) Those components that are fitted and tested as part of the vehicle, whether or not an immobilizer is fitted (e.g. lamps, alarm system, device to prevent unauthorized use by mean of a locking system); or

(b) Those components that have previously been tested as part of the vehicle and documentary evidence has been provided.

All components of the immobilizer shall operate without any failure under the following conditions.

1.1. Climatic conditions

Two classes of environmental temperature are defined as follows:

(a) – 40 °C to + 85 °C for parts to be fitted in the passenger or luggage compartment,

(b) – 40 °C to + 125 °C for parts to be fitted in the engine compartment unless otherwise specified.

1.2. Degree of protection for installation

The following degrees of protection in accordance with IEC publication 60529:1989 shall be provided:

(a) IP 40 for parts to be fitted in the passenger compartment,

(b) IP 42 for parts to be fitted in the passenger compartment of roadsters/convertibles and cars with moveable roof-panels if the installation location requires a higher degree of protection than IP 40,

(c) IP 54 for all other parts.

The immobilizer manufacturer shall specify in the installation instructions any restrictions on the positioning of any part of the installation with respect to dust, water and temperature.

1.3. Weatherability

7 days according to IEC publication 60068-2-30:1980.

1.4. Electrical conditions

Rated supply voltage: 12 V

Operation supply voltage range: from 9 V to 15 V in the temperature range according to paragraph 1.1.1

Time allowance for excess voltages at 23 °C:

U = 18 V, max. 1 h

U = 24 V, max. 1 min.

2. Test conditions

All the tests shall be carried out in sequence on a single immobilizer. However, at the discretion of the test authority, other samples may be used if this is not considered to affect the results of the other tests.

2.1. Normal test conditions

Voltage U = (12 ± 0,2) V

Temperature T = (23 ± 5) °C

3. Operation test

All components of the immobilizer shall comply with prescriptions given in paragraphs 3.2. to 3.9. of this Regulation.

3.1. Upon completion of all the tests specified below, the immobilizer shall be tested under the normal test conditions specified in paragraph 2.1. of this Regulation to check that it continues to function normally. Where necessary, fuses may be replaced prior to the test.

If some of the tests required in each of these paragraphs prior to the operation tests are performed in series on a single immobilizer, the operation test may be carried out one time only after the chosen tests are completed instead of performing the operation tests required in the paragraphs after each of the chosen tests. Vehicle manufacturers and suppliers have to guarantee satisfactory results only on non-accumulated procedures.

3.2. Resistance to temperature and voltage changes

Compliance with the specifications defined under paragraph 3.1 shall also be checked under the following conditions:

3.2.1. Test temperature T (– 40 ± 2) °C Test voltage U = (9 ± 0,2) V Storage duration 4 hours

3.2.2. For parts to be fitted in the passenger or luggage compartment: Test temperature T = (+ 85 ± 2) °C Test voltage U = (15 ± 0,2) V Storage duration 4 hours

3.2.3. For parts to be fitted in the engine compartment unless otherwise specified: Test temperature T = (+ 125 ± 2) °C Test voltage U = (15 ± 0,2) V Storage duration 4 hours

3.2.4. The immobilizer, in both set and unset state, shall be submitted to an excess voltage equal to (18 ± 0,2) V for 1 hour.

3.2.5. The immobilizer, in both set and unset state, shall be submitted to an excess voltage equal to (24 ± 0,2) V for 1 min.

3.3. Safe operation after foreign body and water-tightness testing

After the test for tightness to foreign body and water according to IEC publication 60529:1989 for degrees of protection as in paragraph 1.1.2., the operation tests according to paragraph 3.1. shall be repeated.

With the agreement of the Technical Service this requirement need not apply in the following circumstances:

(a) Type Approval of an immobilizer which is to be type approved as a separate technical unit In this case, the manufacturer of the immobilizer shall: (i) Specify in item 4.5. of the information document (Annex 1 b), that the requirement of this paragraph was not applied to the immobilizer (in accordance with paragraph 7. of this Regulation), and (ii) Specify in item 4.1. of the information document, the list of vehicles to which the immobilizer is intended to be fitted and the relevant installation conditions in item 4.2.

(b) Type approval of a vehicle in respect of an immobilizer In this case, the manufacturer shall specify in item 3.1.1.1. of Annex 1a of the information document (Annex 1a), that the requirement of this paragraph does not apply to the immobilizer due to the nature of installation conditions and the vehicle manufacturer shall prove it by submitting related documents.

(c) Type approval of a vehicle in respect of the installation of an immobilizer which is type approved as a separate technical unit.

In this case, the vehicle manufacturer shall specify in item 3.1.1.1. of Annex 1a of the information document (Annex 1a), that the requirement of this paragraph does not apply to the installation of the immobilizer where the relevant installation conditions are met.

This requirement does not apply in cases where the information required in item 3.1.3.1.1. of Annex 1a has already been submitted for the approval of the separate technical unit.

3.4. Safe operation after condensed water test

After a resistance-to-humidity test to be carried out according to IEC publication 60068-2-30:1980 the operation tests according to paragraph 3.1. shall be repeated.

3.5. Test for safety against reversed polarity

The immobilizer and components thereof shall not be destroyed by reversed polarity up to 13 V during 2 min. After this test the operation tests according to paragraph 3.1. shall be repeated with fuses changed, if necessary.

3.6. Test for safety against short-circuits

All electrical connections of the immobilizer must be short-circuit proof against earth, max. 13 V and/or fused. After this test the operation tests according to paragraph 3.1. shall be repeated, with fuses changed if necessary.

3.7. Energy consumption in the set condition

In this case, the vehicle manufacturer shall specify in item 3.1.3.1.1. of the information document (Annex 1a), that the requirement of this paragraph does not apply to the installation of the immobilizer where the relevant installation conditions are met. This requirement does not apply in cases where the information required in item 3.1.3.1.1. of Annex 1a has already been submitted for the approval of the separate technical unit.

3.8. Safe operation after vibration test

3.8.1. For this test, the components are subdivided into two types: Type 1 : components normally mounted on the vehicle, Type 2 : components intended for attachment to the engine.
