Note 2: as specified in U.S. government regulations, the term VOCs is limited to those compounds with photochemical activity in the atmosphere (see ASTM D3960), while any other compounds are defined as exempt compounds. [See ISO 4618: 2006] Note 3: as specified in European regulations such as European Union directive 2004/42/EC, the term VOCs refers to the volatile organic compounds with boiling points up to 250℃ under 101.325kPa of standard pressure. 3.9 volatile organic compounds content, VOCs content content of volatile organic compounds measured in the coatings under specified condition Note 1: the property and quantity of compound to be considered depend on the application field of coating. For each application field, the determination or calculation method and the limit are specified by laws or agreed by both parties. [See ISO 4618: 2006] Note 2: if the term VOCs refers to compounds defined with the highest boiling point, the compounds with boiling points lower than the limit are taken as VOCs content, while those with boiling points higher than the limit are taken as non-volatile organic compounds. 4 Requirements High solids, ultra high solids and solvent-free epoxy coating shall meet the requirements of Table 1. ?
