1 The limits and methods of measurement laid down in this publication apply to industrial, scientific and medical (ISM) equipment as defined in Clause 3, and to spark erosion equipment.
2 The assessment of conformity of equipment tested on a test site shall be in accordance with the specifica-tions of Clause 6. For equipment in series production, there shall be 80 % confidence that at least 80% of manufactured items comply with the limits given. The statistical assessment procedure is specified in sub-clause 6.3. For small scale production the application of the statistical assessment may not always be econo-mical. In such cases the assessment procedure contained in subclause 6.2 may be applied. Measurement results obtained for an equipment measured in its place of use and not on a test site shall relate to that insta-llation only, and shall not be considered representative of any other installation and so shall not be used for the purpose of a statistical assessment.
