This Standard provides a practical procedure for use in the field to determine the surface temperature of a metal substrate to which a protective coating is to be applied to confirm that the metal temperature is an appropriate margin above the dewpoint temperature. The range of surface temperature measurements covered by this Standard is limited to ambient (field) applications.

This Standard provides a practical procedure for use in the field to determine the surface temperature of a metal substrate to which a protective coating is to be applied to confirm that the metal temperature is an appropriate margin above the dewpoint temperature. The range of surface temperature measurements covered by this Standard is limited to ambient (field) applications. Applications of coatings to ‘hot’ surfaces above 80°C are not covered by this Standard.NOTE: AS/NZS 2312 provides guidance on atmospheric conditions and their affect on painting conditions involving iron and steel substrates. It recommends that the surface temperature is at least 3°C above the dewpoint.
