Forms the first of a set dealing with tests of pumps and specifies precision class tests (former class A). Engineering class I and class II tests (former classes B and C) will be the subject of a further standard. Defines the terms and quantities that are used and specifies general requirements for tests. Does not specify constructional tolerances.
