... When any of these conditions is not met, the system suffers a phase transition to enforce stability. Phase transitions are classified into first and second order. In a first order phase transition the extensive quantities s, e, and v are discontinuous while the intensive ones T , p and µ are always ...

Registration, Evaluation, Authorisation and Restriction of Chemicals
Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) is a European Union regulation dated 18 December 2006. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment. Its 849 pages took seven years to pass, and it has been described as the most complex legislation in the Union's history and the most important in 20 years. It is the strictest law to date regulating chemical substances and will affect industries throughout the world. REACH entered into force in 1 June 2007, with a phased implementation over the next decade. The regulation also established the European Chemicals Agency, which manages the technical, scientific and administrative aspects of REACH.
