Estimation of uncertainty of measurement.

-

-

-

-

-

a.

Testing laboratories shall have and shall apply procedures for estimating uncertainty of measurement. The laboratory shall at least attempt to identify all the components of uncertainty and make a reasonable estimation, and shall ensure that the form of reporting of the result does not give a wrong impression of the uncertainty. Reasonable estimation shall be based on knowledge of the performance of the method and on the measurement scope and shall make use of, for example, previous experience and validation data.

-

-

-

-

-

b.

In those cases where a well-recognized test method specifies limits to the values of the major sources of uncertainty of measurement and specifies the form of presentation of calculated results, the laboratory is considered to have satisfied this clause by following the test method and reporting instructions.

-

-

-

-

-

c.

When estimating the uncertainty of measurement, all uncertainty components which are of importance in the given situation shall be taken into account using appropriate methods of analysis.

-

-

-

-

-

d.

Sources contributing to the uncertainty include, but are not necessarily limited to, the reference standards and reference materials used, methods and equipment used, environmental conditions, properties and condition of the item being tested or calibrated, and the operator.

-

-

-

-

-

e.

Test methods are classified as either qualitative or quantitative. Qualitative tests are defined as having nonnumerical results. Although estimation of measurement uncertainty is not needed for these tests, laboratories are expected to have an understanding of the contributors to variability of the results. For quantitative tests, laboratories shall determine measurement uncertainty using appropriate statistical techniques.

-

-

-

-

-

f.

Laboratories shall make independent estimations of uncertainty for tests performed on samples with significantly different matrices.

-

-

-

-

-

g.

Laboratories are required to re-estimate measurement uncertainty when changes to their operations are made that may affect sources of uncertainty.

-

-

-

-

-

h.

When reporting measurement uncertainty, the test report shall include the coverage factor and confidence level used in the estimations (typically k = approximately 2 at the 95% confidence level).

-

-

-

-

-

34.

-

-

-

-

-

-

-

-

-

-

a.

The procedure for corrective action shall start with an investigation to determine the root cause(s) of the problem.

-

-

-

-

-

b.

-

e.
