GB/T 28470-2012Methods of evaluating the performance of electrical and pneumatic analogue computing unit for use in industrial process measurement and control systems (English PDF)

Foreword

This standard rule according to GB/T 1.1-2009 given draft. Appendix A of this standard is a normative appendix. The standard proposed by China Machinery Industry Federation.

1 Scope

This standard specifies the harmonized test methods of performance evaluation simulation calculator.

This standard applies to comply with the following calculators.

a) industrial process measurement and control systems;

b) input and output signals in line with the provisions of GB/T 777 or GB/T 3369.1 or GB/T 3369.2's;

c) operation mode of addition and subtraction, multiplication and division, or prescribing;

d) Under normal working conditions.

Input and output analog signals to other calculators or other operation mode (such as the ratio of operation) calculator, can also refer to adopt.

For special working conditions as well as other types of calculators, according to the specific circumstances of the calculator, selection criteria applicable test Supplementary and additional tests required.
