Commission Directive 2012/49/EUShow full title

PART I Supplementary provisions

1. Marking of on-board sewage treatment plants

1.1 The type-tested on-board sewage treatment plant must bear the following information (marking):

1.1.1

manufacturer’s trademark or trade name;

1.1.2

on-board sewage treatment plant type and serial number of the plant;

1.1.3

number of the type approval in accordance with Part IV of this Appendix;

1.1.4

year of construction of the on-board sewage treatment plant.

1.2 The marking in accordance with point 1.1 must be durable, clearly legible and indelible throughout the working life of the on-board sewage treatment plant. If adhesive labels or plates are used, they must be affixed so as to stay on throughout the working life of the on-board sewage treatment plant and in such a way that they cannot be removed without being destroyed or rendered indecipherable.

1.3 The marking must be affixed to a part of the on-board sewage treatment plant necessary for normal operation of the on-board sewage treatment plant and not normally requiring replacement during the working life of the on-board sewage treatment plant.

1.3.1

The marking must be affixed in such a way that it is clearly visible after the on-board sewage treatment plant has been fitted with all the auxiliary equipment necessary for its operation.

1.3.2

If necessary, the on-board sewage treatment plant must bear an additional removable plate made of a durable material which must contain all the information in referred to in point 1.1 and which shall be affixed in such a way that that information is clearly legible and easily accessible after the on-board sewage treatment plant has been installed in a craft.

1.4 All parts of the on-board sewage treatment plant which may have an effect on the treatment of sewage must be clearly marked and identified.

1.5 The exact location of the marking referred to in point 1.1 shall be indicated in Section I of the type approval certificate.

2. Testing

The procedure for testing an on-board sewage treatment plant is laid down in Appendix VII.

3. Evaluation of conformity of production

3.1 With regard to the verification of the existence of satisfactory arrangements and procedures for ensuring effective control of production conformity before granting type approval, the competent authority must accept the manufacturer’s registration to harmonised standard EN ISO 9001:2008 (whose scope covers the production of the on-board sewage treatment plants concerned) or an equivalent accreditation standard as satisfying the requirements. The manufacturer must provide details of the registration and undertake to inform the competent authority of any revisions to its validity or scope. Appropriate production inspections shall be carried out in order to ensure that the requirements of Article 14a.02(2) to (5) are consistently being fulfilled.

3.2 The holder of the type approval must:

3.2.1

ensure that procedures are in place for the effective control of the quality of the product;

3.2.2

have access to the testing equipment necessary for checking conformity with each type-approved type;

3.2.3

ensure that the results of the tests are recorded and that these records and the relevant documentation remain available for a period to be agreed with the competent authority;

3.2.4

analyse closely the results of each type of test, in order to verify and ensure the consistency of the on-board sewage treatment plant’s characteristics, making allowance for normal variations in series production;

3.2.5

ensure that any samples from on-board sewage treatment plants or test pieces revealing apparent non-conformity in the type of test in question give rise to further sampling and testing, all necessary measures being taken to restore conformity of production.

3.3 The competent authority which has granted type approval may at any time verify the conformity control methods applied at each production works.

3.3.1

The test and production documentation shall be made available to the tester at each test.

3.3.2

If the quality of the tests appears unsatisfactory, the following procedure shall be applied:

3.3.2.1

one on-board sewage treatment plant shall be taken from the series and tested by means of random sample measurements in the normal load condition of the Appendix VII after one day operation. The treated sewage must according to the test methods in Appendix VII not exceed the values set out in Article 14a.02(2), Table 2;

3.3.2.2

should any on-board sewage treatment plant taken from the series fail to satisfy the requirements laid down in point 3.3.2.1 the manufacturer may ask for random sample measurements to be carried out on a number of on-board sewage treatment plants of the same specification taken from the series. This new sample must include the on-board sewage treatment plant originally taken. The manufacturer shall determine the scope n of the series in consultation with the competent authority. The on-board sewage treatment plants shall undergo testing by means of random sample measurement with the exception of the plant originally taken. The arithmetical mean of the results obtained with the random sample of the on-board sewage treatment plant must then be determined. The series production shall be regarded as conforming with requirements if the following condition is fulfilled:

where:

k

is a statistical factor which is dependent on n and is given in the following table:

n	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19
k	0,973	0,613	0,489	0,421	0,376	0,342	0,317	0,296	0,279	0,265	0,253	0,242	0,233	0,224	0,216	0,21	0,203	0,198

if n≥20,

S_t =

, where x_i is any individual result obtained from the random sample n;

L

is the admissible limit value set out in Article 14a.02(2) Table 2 for each pollutant studied;

3.3.3 if the values as set out in Article 14a.02(2), Table 2 are not complied with, a new test shall be carried out according to point 3.3.2.1 and, in case that tests has no positive results, in accordance with point 3.3.2.2 a full test is carried out, following the test procedure provided in Appendix VII. The limit values as set out in Article 14a.02(2), Table 1 may not be exceeded for either the composite sample or the random sample.

3.3.4 The competent authority must carry out the tests on on-board sewage treatment plants which are partially or fully functional according to the information supplied by the manufacturer.

3.3.5 The normal frequency of tests of conformity of production which the competent authority is entitled to conduct shall be one per year. In case of non-compliance with the requirements of point 3.3.2 the competent authority shall ensure that all necessary steps are taken to restore production conformity without delay.
