Bibliography

This European Standard specifies a method to determine the migration of substances from factory made cementitious products into test waters after contact with the products.This European Standard is applicable to factory made cementitious products, e.g. cement mortar linings to metallic pipes, tanks, concrete pipes etc., intended to be used for the transport and storage of water intended for human consumption, including raw water used for the production of drinking water.
