This standard is used to evaluate changes in the performance of water-based paints after freezing and thawing cycles. Since freezing and thawing are more damaging to water-based paints than stable freezing, this test method focuses on the effect of freezing-thaw cycles on Coating viscosity and film Appearance to help understand Coating durability in cold climates. SI units are standard units, values in brackets are for reference only. It is up to the user to determine the applicable safety measures.
