Foreword
GB/T 18271 "Universal Performance Evaluation Methods and Procedures for Process Measurement and Control Devices" currently plans to release the following parts.
--- Part 1. General Provisions;
--- Part 2. Test under reference conditions;
--- Part 3. Experiments on the influence of the quantity;
--- Part 4. The content of the assessment report.
This part is Part 2 of GB/T 18271.
This section was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 18271.2-2000 "General performance evaluation methods and procedures for process measurement and control devices. Part 2.
Compared with the test under reference conditions, compared with GB/T 18271.2-2000, the main technical changes are as follows.
--- Updated normative references, replacing GB/T 17212-1998 with GB/T 2900.56-2008 (see Chapter 2,.2000)
Chapter 2 of the edition);
--- Deleted the terms "tested device", "set point", "adjustability", "instantaneous overshoot", "unexpected event" and definition (2000 version 3.1,
3.6, 3.15, 3.21, 3.22);
--- The term "maximum measurement error" is adjusted to "measurement error" (see 3.7; 3.9 in the.2000 edition);
--- Modified the definition of the terms "non-repeatability" and "step response time" (see 3.10, 3.16; 3.12, 3.19 of the.2000 edition);
--- Added the terms "type test" "performance evaluation" "routine test" and "sampling test" and definition (see 3.19 ~ 3.22);
--- Table 1, Table 2 added "full performance test" and "simplified test" classification (see Table 1, Table 2);
--- Modified the typical air flow characteristic curve of Figure 6 (see Figure 6 of the.2000 edition);
--- The requirement for verifying unidirectional drift or random drift has been added to long-term drift (see 7.2).
The translation method used in this section is equivalent to the use of IEC 61298-2..2008 "General performance evaluation methods and procedures for process measurement and control devices
Part 2. Test under reference conditions ".

General performance assessment methods and procedures
Part 2. Test under reference conditions
1 Scope
GB/T 18271 stipulates a general method for performing functional and performance characteristics tests of process measurement and control devices and preparing test reports
Laws and procedures. These experiments are applicable to any specific input and output variables, and there is a specific relationship between input and output variables (transfer function
Several) process measurement and control devices, including analog devices and digital devices. For devices that require special test items, the
GB/T 18271 is combined with product standards that have special regulations for such special test items.
This part of GB/T 18271 discusses tests conducted under reference conditions.
