11 Expression of results
Report the mass fraction of water in the sample to the nearest 0.001 % (m/m)
12 Precision
12.1 Repeatability, r
The difference between two test results obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, in the normal and correct operation of the test method, exceed the following value in only one case in twenty:
where X is the average of the test values being compared.
12.2 Reproducibility, R
The difference between two single and independent test results obtained by different operators working in different laboratories on identical test material would, in the long run, in the normal and correct operation of the test method, exceed the following value in only one case in twenty:
where X is the average of the test results being compared.
13 Test report
The test report shall contain at least the following information:
a) a reference to this International Standard;
b) the type and complete identification of the product tested;
c) whether the sample was, or was not, clear and bright, and whether water droplets or particulate matter were observed on swirling;
d) if the sample was not clear and bright, or if water droplets or particulate matter were observed on swirling:
- the type, concentration and quantity of emulsifier used (see clause 6);
- the type of mixer, mixing time, mixing speed and the approximate position of the mixer relative to the bottom of the sample container;
- the temperature of the sample before and after mixing;
e) the result of the test (see clause 11);
f) any deviation, by agreement or otherwise, from the procedure specified;
g) the date of the test.
