Any other information on results incl. tables

The vapour pressure of the test item MADERAL ZA1076 was determined at three different temperatures (30, 40 and 50 °C) following EU A.4 using the effusion method (weight loss). All experiments could be evaluated as they showed relevant and reproducible weight loss. All evaluated experiments showed good reproducibility, giving relative standard deviations of less than 6 % and very good correlation. Therefore, the result of the test can be considered valid.
