1. Checks for conformity with the standards prescribed in this annex shall be made:

a) before equipment enters into service;

b) periodically, at least once every six years; and

c) whenever required by the competent authority.

Except in the cases provided for in appendix 2, sections 5 and 6, to this annex, the checks shall be made at a testing station designated or approved by the competent authority of the country in which the equipment is registered or recorded, unless, in the case of the check referred to in (a) above, a check has already been made on the equipment itself or on its prototype in a testing station designated or approved by the competent authority of the country in which the equipment was manufactured.

2. The methods and procedures to be used in checking for compliance with the standards are described in appendix 2 to this annex.

3. A certificate of compliance with the standards shall be issued by the competent authority of the country in which the equipment is to be registered or recorded. This certificate shall conform to the model reproduced in appendix 3 to this annex.

The certificate of compliance shall be carried on the equipment during carriage and be produced whenever so required by the control authorities. However, if a certification plate of compliance, as reproduced in appendix 3 to this annex, is fixed to the equipment, the certification plate of compliance shall be recognized as equivalent to a certificate of compliance. A certification plate of compliance may be fixed to the equipment only when a valid certificate of compliance is available. Certification plates of compliance shall be removed as soon as the equipment ceases to conform to the standards laid down in this annex.

In the case of equipment transferred to another country, which is a Contracting Party to ATP, it shall be accompanied by the following documents so that the competent authority of the country in which the equipment is to be registered or recorded can issue a certificate of compliance:

a) in all cases, the test report of the equipment itself or, in the case of serially produced equipment, of the reference equipment;

b) in all cases, the certificate of compliance issued by the competent authority of the country of manufacture or, for equipment in service, the competent authority of the country of registration. This certificate will be treated as a provisional certificate, if necessary, with a maximum validity of six months. For multi-temperature, multi-compartment equipment also the declaration of conformity (see 7.3.6 of annex I, appendix 2) shall be provided;

c) in the case of serially produced equipment, the technical specification of the equipment to be certified as issued by the manufacturer of the equipment or his duly accredited representative (this specification shall cover the same items as the descriptive pages concerning the equipment which appear in the test report and shall be drawn up in at least one of the official languages). For multi-temperature, multi-compartment equipment also a calculation sheet (see 7.3.6 of annex I, appendix 2) based on the iterative method shall be provided.

In the case of equipment transferred after it has been in use, the equipment may be subject to a visual inspection to verify its conformity before the competent authority of the country, in which it is to be registered or recorded, issues a certificate of compliance.

4. Distinguishing marks and particulars shall be affixed to the equipment in conformity with the provisions of appendix 4 to this annex. They shall be removed as soon as the equipment ceases to conform to the standards laid down in this annex.

5. The insulated bodies of ‘insulated’, ‘refrigerated’, ‘mechanically refrigerated’, ‘heated’ or ‘mechanically refrigerated and heated’ transport equipment and their thermal appliances shall each bear a durable manufacturer’s plate firmly affixed by the manufacturer in a conspicuous and readily accessible position on a part not subject to replacement in use. It shall be able to be checked easily and without the use of tools. For insulated bodies, the manufacturer’s plate shall be on the outside of the body. The manufacturer’s plate shall show clearly and indelibly at least the following particulars:

3) These requirements shall apply to new plates only. A transitional period of three months shall be granted from the date of entry into force of this requirement.

Country of manufacture or letters used in international road traffic;

Name of manufacturer or company;

Model (figures and/or letters);

Serial number;

Month and year of manufacture.

6.

a) New equipment of a specific type serially produced may be approved by testing one unit of that type. If the unit tested meets class specification, the resulting test report shall be regarded as a Type Approval Certificate. This certificate shall expire at the end of a period of six years beginning from the date of completion of the test.

The date of expiry of test reports shall be stated in months and years.

b) The competent authority shall take steps to verify that production of other units is in conformity with the approved type. For this purpose it may check by testing sample units drawn at random from the production series.

c) A unit shall not be regarded as being of the same type as the unit tested unless it satisfies the following minimum conditions:

(i) If it is insulated equipment, in which case the reference equipment may be insulated, refrigerated, mechanically refrigerated, heated or mechanically refrigerated and heated equipment,

the construction shall be comparable and, in particular, the insulating material and the method of insulation shall be identical;

the thickness of the insulating material shall be not less than that of the reference equipment;

the interior fittings shall be identical or simplified;

the number of doors and the number of hatches or other openings shall be the same or less; and

the inside surface area of the body shall not be as much as 20% greater or smaller;

minor and limited modifications of added or exchanged interior and exterior fittings may be permitted:

* The present provisions regarding minor and limited modifications apply to equipment manufactured after the date of their entry into force (date to be included).

• if the equivalent volume of accumulated insulation material of all such modifications is less than 1/100th of the total volume of the insulating material in the insulated unit;

• if the K coefficient of the tested reference equipment, corrected by a calculation of the added thermal losses, is less than or equal to the K coefficient limit of the category of the equipment; and

• if such modifications of interior fittings are carried out using the same technique, particularly as concerns glued fittings.

All modifications shall be done by or be approved by the manufacturer of the insulated equipment.

(ii) If it is refrigerated equipment, in which case the reference equipment shall be refrigerated equipment,

the conditions set out under (i) above shall be satisfied;

inside circulating fans shall be comparable;

the source of cold shall be identical; and

the reserve of cold per unit of inside surface area shall be greater or equal;

(iii) If it is mechanically refrigerated equipment, in which case the reference equipment shall be either:

a) mechanically refrigerated equipment;

– the conditions set out in (i) above shall be satisfied; and

– the effective refrigerating capacity of the mechanical refrigeration appliance per unit of inside surface area, under the same temperature conditions, shall be greater or equal;

or

b) insulated equipment which is complete in every detail but minus its mechanical refrigeration unit which will be fitted at a later date.

The resulting aperture will be filled, during the measurement of the K coefficient, with close fitting panels of the same overall thickness and type of insulation as is fitted to the front wall. In which case:
