ISO 12944-9 uses three well established laboratory procedures as its 7 day test cycle:
• 72 hours accelerated UV weathering in accordance with ISO 16474-3 / Method A / Cycle 1 (formally ISO 11507)
• 72 hours neutral salt spray exposure in accordance with ISO 9227
• 24 hours steady state low temperature testing at -20˚C
This tough test regime is repeated for up to 25 cycles (4200 hours) and only the most durable of coating systems will withstand this test cycle and exposure period.
ISO 12944-6 testing alongside ISO 12944-9 are used to demonstrate the durability of new paint systems. Durability categories are assessed at AWL Ltd after the humidity condensation test (ISO 6270-2), the neutral salt spray test (ISO 9227), and resistance to the effects of water or chemicals (ISO 2812-1 or 2812-2).
