CLP and testing of hazardous substances

CLP stands for “classification, labeling, and packaging” and determines whether a substance or mixture should be classified and labelled as hazardous (Regulation (EC) No 1272/2008 on classification, labeling and packaging of chemicals). The objective of the CLP Regulation is to ensure a high level of protection of health and the environment, as well as the free movement of substances, mixtures and articles.

On the December 19, 2022, the European Commission proposed a revised CLP Regulation and introduced new hazard classes for endocrine disruptors and other harmful chemical substances. In addition, the processes and communication to inform on hazards of chemicals placed in the EU market will be improved. 

Physical hazards

The CLP Regulation requires manufacturers, importers or downstream users of substances or mixtures to classify, label and package their hazardous chemicals appropriately before placing them on the market. Annex I – Part 2 in the CLP Regulation concerns physical hazards related to

  • explosives,
  • flammable gases, liquids, aerosols, and solids,
  • gases under pressure,
  • self-reactive substances and mixtures,
  • pyrophoric liquids and solids,
  • self-heating substances and mixtures,
  • substances and mixtures which in contact with water emit flammable gases,
  • oxidising gases, liquids, and solids,
  • organic peroxides,
  • corrosive to metals.

ATEX and CLP overlap for several of the of the substances on the list. This includes flammable gases, liquids, aerosols, and solids. For some substances the material testing can be performed according to ATEX Harmonised Standards. An example is combustible dust in bulk, where the spontaneous ignition behavior of dust accumulations is determined according to ATEX Harmonised Standard EN 15188:2020.
