PARTICIPATION AND PERFORMANCE OF TESTS
An Interlaboratory test campaign is organized each year by Atil. In particular, the following are participating in the Cement Industry laboratories in France and in Europe, the laboratories of Cement Users and research and control centers in the field of construction materials.
This participation is compulsory for laboratories accredited by Cofrac for tests on cements. The tests are carried out according to standardized methods when they exist and according to current and traditional methods otherwise.
The elimination of outliers is performed at the 98% level by Student’s test. A reiteration is fixed at this threshold, in order to keep only the values attached to the “Normal or Gaussian” distribution and entirely defined by the two parameters: mean and standard deviation. The coefficient of variation symbolized by “V” is the ratio between the standard deviation “” and the mean “X”.
We offer the following list of equivalences: NIST, CCRL, NCBM or others.
