EN 14104 Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of acid value
11 Precision
11.1 Interlaboratory test
Details of interlaboratory test are given in annex A. The values derived from these tests may not be applicable to concentration ranges and matrices other than those given.

11.2 Repeatability
The absolute difference between two independent single test results, obtained using the same method on identical test material in the same laboratory by the same operator using the same equipment within a short interval of time, shall not be greater than 0.02 mg KOH/g more than once out of 20 determinations.

11.3 Reproducibility
The absolute difference between two single test results, obtained using the same method on identical test material in different laboratories with different operators using different equipment, shall not be greater than 0.06 mg KOH/g more than once out of 20 determinations.

12 Test report
The test report shall specify:
- all information necessary for the complete identification of the sample;
- the sampling method used if known;
- the test method used, with reference to this European standard;
- all operating details not specified in this European Standard, or regarded as optional, together with details of any incidents which may have influenced the test result(s);
- the test result(s) obtained, or if the repeatability has been checked, the final quoted result obtained.
