 On this page you will find common terms and acronyms associated with CLP. 

  
 ATE  Acute toxicity estimate
 BCF  Bioconcentration Factor
 CA  Competent Authority 
The national body or bodies established by each Member State to enforce CLP and carry out the regulators’ obligations in the relevant member State.
 CHIP  Chemicals (Hazard Information and Packaging for Supply) Regulations
 CLP  Classification, Labelling and Packaging Regulation, EC No 1272/2008
CLP is an EU Regulation applying directly in all 27 Member States. It also applies to the three member countries of the European Economic Area: Iceland, Liechtenstein and Norway.
 Concentration limit  A threshold at which a substance (or an additive or impurity) triggers classification (and labelling).
Cut-off value The threshold at which substances (or additives or impurities) are taken into account when considering classification. For example, if the concentration of substance A in a mixture is less than the relevant cut-off then substance A does not contribute to the classification of the mixture.
  
 DSD  Dangerous Substances Directive, 67/548/EEC
 DPD  Dangerous Preparations Directive, 1999/45/EC
 EEA  European Economic Area. 
 GHS  Globally Harmonized System of Classification and Labelling of Chemicals (GHS)
 Hazard category  The division of criteria within each hazard class, specifying hazard severity.
 Hazard class  The nature of the physical, health or environmental hazard.
 Hazard pictogram  A graphical composition that includes a symbol plus other graphic elements, such as a border, background pattern or colour that is intended to convey specific information on the hazard concerned.
 Hazard statement (H statement)  A phrase assigned to a hazard class and category that describes the nature of the hazards of a hazardous substance or mixture, including, where appropriate, the degree of hazard.
 HSE  UK Health and Safety Executive
The Competent Authority for REACH and CLP in the UK
  
 Intermediate packaging Packaging placed between inner packaging, or articles, and outer packaging.
 Koc Adsorption Coefficient (water / sediment)
 Kow Partition Coefficient, octanol water (also Pow)
 LD / LC / EC / IC50  Lethal Dose / Lethal Concentration / Effect Concentration / Inhibition Concentration
 LOAEL  Lowest Observed Adverse Effect Level
 M-factor A multiplying factor.
M-factors are applied to the concentration of a substance classified as hazardous to the aquatic environment acute category 1 or chronic category 1, and are used to derive by the summation method the classification of a mixture in which the substance is present.
 MoS  Margin of Safety
 NOEC  No Observed Effects Concentration
 NO(A)EL  No Observed (Adverse) Effect Level
  
 Package The complete product of the packing operation, consisting of the packaging and its contents
 Packaging One or more receptacles and any other components or materials necessary for the receptacles to perform their containment and other safety functions
 PBT Persistent, Bioaccumulative, Toxic Substances of concern which are very persistent (very difficult to break down) and very bio-accumulative in the body tissue of living organisms. REACH Annex XIII defines criteria for the identification of PBTs and REACH Annex I lays down general provisions for their assessment.
 pKa Dissociation constant
 Pow Partition Coefficient, octanol / water (also Kow)
 P-statement Precautionary statement (P statement) A phrase that describes recommended measure(s) to minimise or prevent adverse effects resulting from exposure to a hazardous substance or mixture due to its use or disposal
 Signal word A word that indicates the relative level of severity of hazards to alert the reader to a potential hazard;

The following two levels are distinguished:

(a) ’Danger’ means a signal word indicating the more severe hazard categories;
(b) ‘Warning’ means a signal word indicating the lesssevere hazard categories;
 STOT  Specific Target Organ Toxicity (organs of body affected by over exposure, e.g. liver)
 vPvB Very Persistent, very Bioaccumulative
Substances of concern which are very persistent (very difficult to break down) and very bio-accumulative in the body tissue of living organisms. REACH Annex XIII defines criteria for the identification of vPvBs and REACH Annex I lays down general provisions for their assessment.
