14、 Standard applies to electrical and pneumatic analogue chart recorders (for use in industrial process control systems) using analogue signals which are in accordance with IEC 381 and IEC 382. Some tests may not apply to all instruments and additional tests may be required for certain types of record
15、ers. This standard is intended to provide technical guidance for inspection and routine testing of electrical and pneumatic analogue chart recorders, for instance, as acceptance tests or after repair. For a full evaluation, IEC 873 should be used. Quantitative criteria for acceptable performance sha
16、ll be established by agreement between manufacturer and user. The requirements of this standard shall be effective when agreed by the manufacturer and the user. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of
17、 this International Standard. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the norma
