Tests to be conducted in compliance with the principles of good laboratory practice.

"3.2 Laboratory testing for the presence of scrapie in ovine and caprine animals

Take a laboratory test sample that is representative of the laboratory bulk sample and sufficient to provide all the specimens, each of at least 1 g, that are required.

Take from the pre-treated laboratory test sample a test specimen of at least 1 g (in mass).

For this purpose, it is sufficient to apply either the EN ISO/IEC standard or the principles of good laboratory practice, except for those tests for which the principles of good laboratory practice have been made mandatory.

The control laboratory shall analyse the laboratory sample for enforcement in at least two independent analyses, and calculate the mean of the results.

This guidance document will also specify, where appropriate, those tests for which the principles of good laboratory practice should be applied.

The reference method for laboratory testing of surfactant ultimate biodegradability in this regulation is based on the en iso standard 14593:

Where considered necessary by the customs office, it initiates, or causes to be initiated, laboratory testing, indicating the objective of the test."

Each Member State shall inform the Commission monthly of favourable and unfavourable results of laboratory testing that has been carried out in its border inspection posts.

The reference method for the laboratory testing of surfactants in this Regulation is based on the Confirmatory test procedure in the OECD method, described in Annex VIII.1.

Tissues from ovine and caprine animals sent for laboratory testing pursuant to the provisions of Annex III, Chapter A, Section II (Monitoring in ovine and caprine animals) shall be examined by a rapid test.

When it has been ascertained from the application file that the pattern conforms to the provisions of this Directive, laboratory tests will be carried out on a number of instruments under the following conditions:

Tissues from ovine and caprine animals sent for laboratory testing pursuant to the provisions of Article 12(2) shall be subject to a histopathological examination as laid down in the latest version of the Manual, except where the material is autolysed.

Take from the pre-treated laboratory test sample a specimen of mass not less than 1 g. For a very fine yarn, the analysis may be made on a minimum length of 30 m, whatever its mass.

The tests specified for the biodegradability of surfactants should be carried out in laboratories meeting an internationally recognised standard, namely EN/ISO/IEC/17025 or the principles of good laboratory practice;

Directive 2004/10/EC of the European Parliament and of the Council of 11 February 2004 on the harmonisation of laws, regulations and administrative provisions relating to the application of the principles of good laboratory practice and the verification of their application for tests on chemical substances (codified version)(21);

Although it is not possible to examine all the products presented for export, because the capacity for laboratory analysis is limited, where the sound and fair marketable quality of a product is the object of definite suspicions further verifications should be carried out; if necessary by means of laboratory testing;

It is therefore appropriate to repeal the requirement for 20 % of consignments of meat imported from the United States of America to be tested for the possible presence of hormones, and in respect of laboratory tests to treat such imports on the same basis as imports of meat from other third countries.

Take from the pre-treated laboratory test sample a specimen of mass not less than 1 g, not including a selvedge with edges carefully trimmed to avoid fraying and running parallel with weft or warp yarns, or in the case of knitted fabrics in the line of the wales and courses.

Paragraph 4.3.1.1 of the interpretative document No 2 specifies that to enable the reaction to fire performance of products to be evaluated, a harmonised solution will be developed which may utilise full or bench scale tests that are correlated to relevant real fire scenarios.

Directive 2004/9/EC of the European Parliament and of the Council of 11 February 2004 on the inspection and verification of good laboratory practice (GLP) (codified version)(22); and Council Directive 86/609/EEC of 24 November 1986 on the approximation of laws, regulations and administrative provisions of the Member States regarding the protection of animals used for experimental and other scientific purposes(23).

Where the laboratory tests are carried out on the basis of suspicion of irregularity, available intelligence, a previous notification from the rapid alert system for food and feed (RASFF) or a safeguard measure, and when testing concerns a substance or a pathogenic agent which presents a direct or immediate animal or public health risk, the official veterinarian responsible for the border inspection post who carried out the test or the competent authority must withhold the consignment from veterinary clearance and release until satisfactory results of the laboratory tests are received.

LABORATORY TESTS

Laboratory testing

reagents, test animals, small laboratory supplies, etc.

These checks may include the taking of samples for laboratory tests;

- as a laboratory internal check on possible experimental errors,

Sampling and laboratory testing for the presence of BSE in bovine animals

Sampling and laboratory testing for the presence of a TSE in ovine and caprine animals

The positions tested by the laboratories shall be indicated in the test report.

The measurement system shall be laboratory tested to check the accuracy of the measured force.

The purpose of these principles of good laboratory practice is to promote the development of quality test data.

Emphasis is put on the sampling procedures, principles and applications of laboratory tests and evaluation of their results, as well as on detailed laboratory techniques.

Where laboratory trials cannot be supportive of efficacy, the performance of field trials alone may be acceptable.

For test items used in field studies (e. g. tank mixes), these may be determined through separate laboratory experiments.

Necessary laboratory tests must be performed with due respect for the principles of 'good laboratory practice' as laid down in Directive 87/18/EEC and for the provisions of Directive 86/609/EEC.

Unless justified, results from laboratory trials shall be supplemented with data from field trials.

Test sample means a sample prepared from a laboratory sample and from which test portions will be taken.

(c) reasonable evidence of the presence of ISAV from two independent laboratory tests such as RT-PCR (Part IV) and IFAT (Part V);

(d) is directed towards both the authorities responsible for the control of ISA and the laboratory personnel performing the tests with regard to this disease.

Laboratory sample means a sample prepared for sending to a laboratory and intended for inspection or testing.

The control laboratory shall analyse the laboratory sample for enforcement in at least two independent analyses, and calculate the mean of the results.

- the test facilities shall be recognised to be in conformity with good laboratory practice in accordance with the principles applicable respectively in the EC and Israel.

A reference substance may be tested as a means of demonstrating that under the laboratory test conditions the response of tested species have not changed significantly.
