WEPAL and QUASIMEME organise proficiency tests with global participation. In January 2011, the activities of both proficiency testing organisations have been merged, resulting in WEPAL-QUASIMEME.
Within WEPAL-QUASIMEME, WEPAL covers the proficiency tests related to the terrestrial environment (e.g. soil, plants, manure, compost and biomass) and freshwater sediment. QUASIMEME covers the proficiency tests organised in the marine environment (e.g. sea water, marine sediment, biota and shellfish toxins.
WEPAL-QUASIMEME is more than a proficiency testing scheme. The routine laboratory performance studies provide the basis of external quality assurance for institutes that make regular chemical measurements in the terrestrial, aquatic and marine enviroment. Most studies have two (marine programmes) or four (other programmes) rounds per annum with per round a minimum of two test materials containing the analytes at different concentrations.
WEPAL-QUASIMEME offers nine worldwide accredited programmes (ISO17043)
|Soil||International Soil-analytical Exchange Programme||ISE|
|Fresh Water Sediment||Sediment Exchange for Tests on Organic Contaminants||SETOC|
|Marine Sediment||Marine Sediment Exchange Programmes||MS|

|Biota||Marine Biota Exchange Programmes||BT|
|Shellfish Toxins||Marine Shellfish toxins Exchange Programmes||BT|
|Plants||International Plant-analytical Exchange Programme||IPE|
|Manure||Manure and Refuse Exchange Programme||MARSEP|
|Biomass||Biomass Exchange Programme||BIMEP|

- Select the programmes and rounds you wish to subscribe to.
- It is strongly advised to join each round organised for a selected exercise in a specific year. Nevertheless, it is also possible to join a single round or a selection of different rounds.
- When your laboratory needs a proforma invoice first, you can request a quotation in the application process.
Each round runs for approximately three months (January-March, April-June, July-September and October-December). Participants can send in results during the entire period of each round. Deadlines for each round are presented in the table below.
