The use fgee the alternative exposure cycle shall be indicated in the test report.

Close attention needs to be given to the execution of the work. It should be emphasized that the paint systems given in Table 3 are made up of different generic types of intermediate-coat paint and topcoat paint. An example of a test report form is given in Annex C. Many other additional tests could be useful in characterizing more precisely the components of a paint.

In ISOrelevant requirements are given for the following: Unless frse agreed, condition the coated test panels for three weeks in accordance with ISO This International Standard places emphasis on high-durability paint systems, with the aim of minimizing maintenance, and hence reducing safety considerations and environmental impact.

The minimum data required for a simple identification check if relevant to the product in question are given in Table 1. In order to establish sufficient corrosion protection and ensure optimum performance of the coating, it is necessary to specify the requirements for the protection paint system s along with the relevant laboratory performance tests to assess its their likely durability. The binder properties infrared spectra and content of functional groups are determined after separation of the resin from the pigment and the solvent.
