Testing of electric and pneumatic analog drawing recorders for industrial process control systems

This part of the scope GB/T 3386 specifies the methods for determining the performance of all electric and pneumatic analog drawing recorders operating with standardized signals for process control, including continuous marking and dotting recorders, as well as multi pen and multi point recorders. Some tests may not be applicable to all recorders, while certain types of recorders may require additional tests. The purpose of this section is to provide a unified test method for the performance evaluation of electric and pneumatic analog drawing recorders for process control using standardized signals. When it is not necessary to conduct a comprehensive evaluation according to this section, only the required tests can be conducted. The test results shall be included in the test report in accordance with the requirements of the relevant provisions of this section. The test report should clarify that the evaluation described in the report is not a comprehensive evaluation and indicate any omitted items. 2 Normative references: The clauses in the following documents become the clauses of this part through the reference of GB/T 3386. For dated reference documents, all subsequent amendments (excluding corrected content) or revisions do not apply to this section. However, parties to agreements based on this section are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest version applies to this section.
