Foreword

GB/T 18271 "Process measurement and control device common performance assessment methods and procedures" is currently planned to release the following part.

- Part 1. General;

- Part 2. Tests under reference conditions;

- Part 3. Tests affecting the impact of quantity;

- Part 4. Assessing the contents of the report.

This part is part 4 of GB/T 18271.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part of the replacement GB/T 18271.4-2000 "Process measurement and control devices General performance assessment methods and procedures Part 4.

Assessment report content ", compared with GB/T 18271.4-2000, the main technical changes are as follows.

--- modified normative reference documents, quoted IEC 60050 series of standards, no longer cited GB/T 17212 (idtIEC 60902) (See Chapter 2; Chapter 2 of the 2000 edition);

- Increased reporting should indicate the requirements of the accredited sponsor and any information relating to the use of proprietary information (see 5.1);

- modified the wording of the second paragraph of the preamble of the report (see chapter 7; chapter 7 of the 2000 edition);

- Added "if any changes or additions to the definition should be stated" (see 14.2).

This part uses the translation method equivalent to the use of IEC 61298-4.:2008 "Process measurement and control devices General performance assessment methods and procedures Part 4. Assessing the contents of the report ".

In this part of the normative reference to the international documents have a consistent correspondence between the following documents.

1 Scope

GB/T 18271 specifies the functional and performance characteristics of the process measurement and control device and the preparation of test reports Law and procedure. These tests apply to any specific input and output variables, and the input and output variables have a specific relationship between (transfer letter Number) of process measurement and control devices, including analog devices and digital devices. For the need to do special test items of the device, should follow GB/T 18271 and in combination with such special test items have a specific product standards for testing.

This part of GB/T 18271 specifies the assessment and testing of process measurement and control devices and the written reports of the results obtained content.

This section specifies the main items contained in the assessment report, but does not specify the format of the presentation of the report (by writing and issuing Report the laboratory to decide).
