GB/T 19870-2018Industrial inspecting thermal imagers (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 19870-2005 "Industrial Detection Infrared Thermal Imager". This standard is compared with GB/T 19870-2005, the main To change as follows.

--- Added the terms and definitions of "minimum resolvable temperature difference" and "feature space frequency" (see 3.13, 3.14);

--- Added "classified by detector type" (see 4.2);

--- Increased the "minimum resolvable temperature difference" requirements and corresponding test methods (see 6.1.7, 7.2.7);

--- Increased "high temperature storage" and "low temperature storage" requirements and test methods (see 6.2.1 and 7.2.10.2, 7.2.10.4);

--- Added "flag, packaging and shipping" requirements (see Chapter 9);

--- Increased the requirements of the "drop test" and test methods (see 6.2.5 and 7.2.10.8);

--- Revised the "scope" (see Chapter 1, Chapter 1 of the 2005 edition);

--- Modified the "working band" (see 5.4, 2005 version 4.2.5);

--- Modify "accuracy" to "maximum allowable error" (see 6.1.3, 5.1.3 of 2005 edition);

--- Revised the "continuous stable working time" requirements and test methods (see 6.1.4, 7.2.4, 2005 version 5.1.5, 6.4.5);

---Modified the "shell protection" requirements (see 6.1.8, 2005 version 5.1.9);

--- Modified the "working temperature" requirements [see 6.2.1a), 2005 edition of 5.1.11.2, 5.1.11.3];

--- Revised the "vibration" requirements and test methods (see 6.2.4, 7.2.10.7, 2005 editions 5.1.11.5, 6.5.7);

--- Revised the "electromagnetic compatibility" requirements and the corresponding test methods (see 6.3, 7.1.2, 2005 editions 5.1.8, 6.4.8);

---Modified "Function Requirements" and "Function Check" (see 6.4, 7.2.12, 2005, 5.2, 6.6);

--- Revised the requirements of "test equipment" (see 7.1.3, 6.3 of the 2005 edition);

--- Removed the terms and definitions of "infrared pixels" and "video output format" (see 3.5, 3.12 in 2005);

--- Removed the terminology, requirements and corresponding test methods for the "feature temperature range" (see 3.7, 5.1.4 and 6.4.4 of the 2005 edition).
