B.2 General The collect of samples for the tests is carried out by TÜV Rheinland do Brasil. B.2.1 Initial or Certification Tests The certification tests and the respective samplings for each product established in this Complement are defined in the annexes B.3.x.1. In case of prototypes, the manufacturer can collect and forward the necessary samples to the Laboratory and/or TÜV Rheinland do Brasil, in accordance with them, and under responsibility of TÜV Rheinland do Brasil. The approval on the tests does not exempt TÜV Rheinland do Brasil about validating the products after the beginning of the operation of the line of production. B.2.2 Surveillance tests The conduction of the surveillance tests will be carried out by TÜV Rheinland do Brasil, being taken from the commerce (or from the factory s logistics) and from the stock of the manufacturer, alternately. The periodicity of the tests performance will be at each 6 months, after the grant of the license for the use of the Conformity Marking. At the end of the cycle of 04 (four) semesters, the sequence must be restarted. The collected samples must be sent to the laboratory within a term of 15 days after the collect. If these samples are not sent within the established term, the certificates will be able to be suspended. The surveillance tests for the products established in this Complement are established in the annexes B.3.x.2. One section of each conductor class will be collected, 1 and 2, made, and for the conductor classes 4, 5 or 6, just on one unique sample (except for standard NBR 247-3, that have a collect according rule nº 85/2003), of its highest conductor class, preferably. For each surveillance test of one kind of product, will be collected one different section, preferably. The necessary quantity is of 1 unit of logistics, if coil of 100m, or if reel, or length of 30 meters, at minimum.
