ISO/TS 23165:2006 幾何学的製品仕様（GPS）—座標測定機（CMM）テストの不確かさの評価に関するガイドライン | ページ 6

3.1

test uncertainty

expanded uncertainty, U , associated solely with the testing equipment and its use in the test, which modifies the conformance and non-conformance zones, in accordance with the decision rule in ISO 14253-1

Note 1 to entry: Test uncertainty is a measure of the quality of the testing equipment and its use in the test. It is not a measure of CMM performance, which is determined from probing error, P , and error of indication for size measurement, E .

Note 2 to entry: Test uncertainty is controlled by and is the responsibility of the tester, who provides and uses the test equipment and suffers a reduced conformance or non-conformance zone in the case of a large test uncertainty.

3.2

tester

party who performs the test defined in the ISO 10360-2

Note 1 to entry: In an acceptance test, the tester can be either the supplier or the customer, possibly represented by a third party.

Note 2 to entry: In a reverification test, the tester is the user, possibly represented by a third party.

Note 3 to entry: The tester is always responsible for the test uncertainty.

3.3

tester counterpart

party other than the tester

Note 1 to entry: In an acceptance test, the tester counterpart can be either the customer or the supplier, possibly represented by a third party.

Note 2 to entry: In a reverification test, the tester counterpart is the user himself, possibly represented by a third party.

3.4

coefficient of thermal expansion

CTE

coefficient of thermal expansion of a material at 20 °C

Note 1 to entry: For the purpose of this Technical Specification, only the CTE of the material standard of size is considered.
