AWL are pleased to be helping Eco-Sol Ltd confirm the weathering durability of their fire-retardant coatings that are impregmated into various types of timber cladding after accelerated weathering in accordance with EN927-6 / Method B. This weathering test is required prior to cone calorimeter flammability testing according to EN 16755 -2017.

This corrosion performance standard still remains popular at AWL, but please remember there are 2 test regimes allowed to reach your required performance standard. One of which requires water condensation AND neutral salt spray testing. The other requires just cyclic ageing in accordance with the old ISO 20340, now ISO 12944-9.
Please also be reminded there are essentially 3 parts to establishing an ISO 12944-6 corrosion performance standard. These are:
- Pre-exposure adhesion tests (test method depends on total dry film thickness)
- The exposure cycles (test regimes 1 or 2)
- Post-exposure adhesion tests.
There may also be a requirement for a Cathodic Disbondment test in accordance with ISO 15711 if coating protection is cathodic rather than just barrier. In the 2018 version of the standard this is a recommendation only. AWL can offer CD testing if required.
All tests must be satisfactory before a certificate of conformance can be issued by AWL Ltd. For more information please contact us
