AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

Ett sätt att undersöka kvaliteten i en lödfog är att kontrollera dess täckningsgrad med hjälp av ultraljud. Detta är en teknik som GKN Aerospace använder, bland annat för att kontrollera lödfogar på en specifik flygmotorkomponent. För att komponenten skall kunna godkännas krävs det att alla fogar uppnår den önskade täckningsgraden. De fogar som inte uppfyller kraven måste lödas om tills de kan godkännas. GKN önskar öka effektiviteten genom att minska behovet av omlödningar.
