ISO 4586‑3:2015 applies to laminates less than 2 mm thick normally intended for bonding to supporting substrates to produce HPL composite panels and establishes a classification system for high-pressure decorative laminates according to their performance and main recommended fields of application, including materials with special characteristics, for example formability or defined reaction to fire. ISO 4586‑3:2015 also specifies requirements for the properties of the various types of laminates covered by this classification system.
