This part of IEC 60873 applies to electrical and pneumatic analogue chart recorders (for use in industrial-process control systems), operating from a standardized signal which may be used in process control. It is intended that continuous and dotted line traces, and multiple pen and multiple-channel instruments should be covered. Some tests may not apply to all instruments and additional tests may be required for certain types of recorders. The object of this standard is 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, or where a recorder is to be used under arduous conditions, (for example, high temperatures), IEC 60873-1 should be used. Whenever possible any tests carried out are to be in accordance with IEC 61298, and the person carrying out the tests needs to have a copy of it to hand and be familiar with it. Quantitative criteria for acceptable performance should be established by agreement between manufacturer and user, and the report on the tests shall make clear which tests were carried out. The requirements of this standard shall be effective when agreed by the manufacturer and the user.
