The competent authority which has granted type-approval may at any time verify the conformity  control methods applicable to each production unit. 2.8.4.1. In every inspection, the test books and production survey records shall be presented to the  visiting inspector. 2.8.4.2. The inspector may take samples at random which will be tested in the manufacturer`s laboratory. The  minimum number of samples may be determined according to the results of the manufacturer's own  verification. 2.8.4.3. When the quality level appears unsatisfactory, or when it seems necessary to verify the validity of  the tests carried out in application of item 2.8.4.2, the inspector shall select samples to be sent  to the technical service which has conducted the type-approval tests. 2.8.4.4. The competent authority may carry out any test prescribed in this Directive. 2.8.4.5. The normal frequency of inspections authorized by the competent authority shall be two per year. In  the case where negative results are recorded during one of these inspections, the competent  authority shall ensure that all necessary steps are taken to re-establish the conformity of  production as rapidly as possible.'Items 3.1 to 3.1.5 are replaced by the following: '3.1. Vehicle equipment (1)3.1.1. Any vehicle covered by Article 9, in categories M and N (except those vehicles which include places  specially designed for standing passengers in categories M2 over 3,5 t and M3 must be equipped with  safety belts or restraint systems which satisfy the requirements of this Directive. 3.1.2. The types of safety belts or restraint systems for each seating position where installation is  required shall be those specified in Annex XV (with which neither non-locking retractors (1.8.1)  nor manually unlocking retractors (1.8.2) can be used). For all seating positions where lap belts  type B are specified in Annex XV lap belts type Br3 are permitted except in the case that, in use,  they retract to such an extent as to reduce comfort in a notable way after normal buckling up. 3.1.3. However, for outboard seating positions, other than front, of vehicles of the category M1 shown in  Annex XV and marked with the symbol o, the installation of a lap belt of the type B, Br3 or Br4m is  allowed, where there exists a passage between a seat and the nearest side wall of the vehicle  intended to permit access of passengers to other parts of the vehicle. A space between a seat and  the side wall is considered as a passage, if the distance between that side wall, with all doors  closed, and a vertical longitudinal plane passing throw the centreline of the seat concerned -  measured at the R-point position and perpendicularly to the median longitudinal plane of the  vehicle - is more than 500 mm. 3.1.4. Where no safety belts are required any type of safety belt or restraint system conforming to this  Directive may be provided at the choice of the manufacturer. A-type belts of the types permitted in  Annex XV may be provided as an alternative to lap belts for those seating positions where lap belts  are specified in Annex XV. 3.1.5. On three point belts fitted with retractors, one retractor must operate at least on the diagonal  strap. 3.1.6. Except for vehicles of category M1 an emergency locking retractor of type 4N (1.8.5) may be  permitted instead of a retractor of type 4 (1.8.4) where it has been shown to the satisfaction of  the services responsible for the tests that the fitting of a type 4 retractor would not be  practical. 3.1.7. For the front outboard and front centre seating positions shown in Annex XV and marked with the  symbol *, lap belts of the type specified on that Annex shall be considered adequate where the  windscreen is located outside the reference zone defined in Annex II to Directive 74/60/EEC. As regards safety belts, the windscreen is considered as part of the reference zone when it is  capable of entering into static contact with the test apparatus according to the method described  in Annex II to Directive 74/60/EEC. 3.1.8. For all seating positions in Annex XV marked with the symbol ll=, lap belts of the types specified  in Annex XV must be provided where an "exposed seating position'` as defined in 3.1.9 exists. 3.1.9. An "exposed seating position'' is one where there is no "protective screen'' in front of the seat  within the following defined space: - between two horizontal planes, one through the H-point and the other 400 mm above it, - between two vertical longitudinal planes which are symmetrical in relation to the H-point and are  400 mm apart, - behind a transverse vertical plane 1,30 m from the H-point. For the purpose of this requirement "protective screen'' means a surface of suitable strength and  showing no discontinuities such that, if a sphere of 165 mm diameter is geometrically projected in  a longitudinal horizontal direction through any point of the space defined above and through the  centre of the sphere, nowhere in the protective screen is there any aperture through which the  geometrical projection of the sphere could be passed. A seat is considered to be an "exposed seating position'', if the protective screens within the  space defined above have a combined surface area of less than 800 cm$.'After item 3.2.2.3, a new  item 3.2.2.4 is added: '3.2.2.4. The design and installation of every safety belt provided for each seating position shall be such  as to be readily available for use. Furthermore, where the complete seat or the seat cushion and/or  the seat back can be folded to permit access to the rear of the vehicle or to carry goods or  luggage, after folding and restoring those seats to the seating position, the safety belts provided  for those seats shall be accessible for use or can be easily recovered from under or behind the  seat by one person, according to instructions in the vehicle users handbook, without the need for  that person to have training or practice.`Item 3.3.2, the fourth sentence is amended as follows: 'In the case of safety belts or restraint systems for front outboard seating positions, except if  these are harness belts, the buckle shall also be capable of being locked in the same manner.`The  last sentence of item 3.3.2 is replaced by the following: 'A check shall be made to ensure that if the buckle is in contact with the wearer, the contact  surface satisfies the requirements of 2.4.2.1 of this Annex.`Annex II, item 1, add: . . ./device for height adjustment of the upper loop In Annex II after the type approval  certificate the following model document shall be added: Appendix 1MODEL DOCUMENTINSTALLATION OF SEAT BELTS AND RESTRAINT SYSTEMS(Maximum format A  4)Name of Administration issuing notification .

In the case of belts fitted with an emergency locking retractor, the following number of samples  shall be subjected to the test prescribed in item 1.6.2 of this Annex: 2.2.2.1.1. for a production of not less than 5 000 belts per day, two belts per 25 000 produced with a minimum  frequency of one per day, per sort of locking mechanism; 2.2.2.1.2. for a production of less than 5 000 belts per day, one belt per 5 000 produced with a minimum  frequency of one per year, per sort of locking mechanism. 2.2.2.2. In the case of belts fitted with an automatically locking retractor and of static belts, the  following number of samples shall be subjected to the test prescribed in item 1.6.2 of this Annex: 2.2.2.2.1. for a production of not less than 5 000 belts per day, two belts per 25 000 produced with a minimum  frequency of one per day, per approved type, 2.2.2.2.2. for a production of less than 5 000 belts per day, one belt per 5 000 produced with a minimum  frequency of one per year, per approved type. 2.2.3. ResultsTest results shall meet the requirements set out in item 2.6.1.3.1 of Annex I. The forward displacement of the manikin may be controlled with regard to item 2.6.1.3.2 of Annex I  (or item 2.6.1.4 where applicable) during a test performed with conditioning according to item  1.6.1 of this Annex by means of a simplified adapted method. 2.3. Where a test sample fails a particular test to which it has been subjected, a further test to the  same requirements shall be carried out on at least three other samples. In the case of dynamic  tests if one of the latter fails the test, the holder of the approval or his duly accredited  representative shall notify the competent authority which has granted type approval indicating what  steps have been taken to re-establish the conformity of production.'(1) OJ N° L 139,  19. 5. 1982, p. 17.
