Standard ref. materials

Standard reference materials alumina 2300 Blaine & 10300 Blaine

STANDARD ALUMINA REFERENCE MR LOW HIGH BLAINE

PARTICIPATION AND ACHIEVEMENT OF TESTS

Inter laboratory testing campaigns, organized by the ATILH or SNL, allowed the preparation of reference materials. European laboratories of cement Industry, users of cement, Research and control Centres in the field of construction materials, have participated in these campaigns.

The analysed materials are of powder type, cement and alumina. The physical and chemical properties measured are:

• fineness and particle size measured with laser,
• chemical composition.

DATA ANALYSIS

Outliers are eliminated via the STUDENT’s test with a confidence level of 98 %. A reiteration is set at this threshold in order to keep only those values which are related to the “Normal or Gaussian” distribution, the latter being entirely defined by 2 parameters: mean and standard deviation.

PACKAGING

Available in vacuum-packed bottles of 45gr.

EQUIVALENCE

We can propose the equivalent to the NIST or CCRL or cement-NCBM
