When manufacturers apply the statistical procedure set out in point 5.10 for the Type 1 test, the number of sample lots shall be set on the basis of the annual sales volume of an in-service family in Great Britain, as described in the following table:
Table B.1
Number of sample lots for ISC testing with Type 1 tests
GB Registrations per calendar year of vehicles in the sampling period
Number of sample lots (for Type 1 tests)
up to 100 000
1
100 001 to 200 000
2
above 200 000
3
Each sample lot shall include enough vehicle types, in order to ensure that at least 20 % of the total family sales are covered. When a family requires more than one sample lot to be tested, the vehicles in the second and third sample lots shall reflect different vehicle use conditions from those selected for the first sample.
