IEC 62828-1:2017

Overview

IEC 62828-1:2017 is an international standard published by the International Electrotechnical Commission (IEC) that defines reference conditions and testing procedures for industrial and process measurement transmitters (PMTs). It applies to all types of PMTs used in industrial process and machinery measurement and control systems. The standard provides a comprehensive framework for assessing transmitter accuracy and reliability through standard and ambient/process reference test conditions.

This standard replaces the older IEC 60770 series and updates parts of IEC 61298, reflecting advances in measurement technology and providing harmonized global testing methods. The harmonized procedures help ensure consistency and quality across industrial measurement devices, fostering interoperability and dependable industrial operations.

Key Topics

• General Framework: Establishes uniform reference conditions-including standard and ambient/process influencing environmental factors-to comprehensively evaluate PMT performance.

• Reference Test Conditions:

  • Standard Reference Conditions: Used primarily to determine accuracy under predefined environmental and operational states.
  • Ambient and Process Reference Conditions: Assess effects of external quantities such as vibration, temperature, humidity, power supply variations, and electromagnetic compatibility (EMC) on measurement accuracy.

• Classification of Tests:

  • Type tests at standard and operating conditions covering accuracy, static and dynamic behavior.
  • Electromagnetic and environmental influence tests including vibration, shock, drop, and EMC.
  • Special procedures for digital transmitters encompassing throughput and fault injection testing.
  • Routine, acceptance, integration, periodic, and maintenance tests for ongoing performance verification.

• Test Report and Documentation Requirements: Detailed guidance on preparing standardized test reports, technical documentation, and analyzing total probable errors to ensure full traceability and compliance.

• Measurement Uncertainty: Procedures for estimating, combining, and expanding measurement uncertainty, enhancing confidence in PMT calibration and operational accuracy.

• Dependability and Fault Testing: Methods for evaluating PMT robustness through design analysis, fault injection, mis-operation, and maintenance error assessments.

Applications

• Industrial Process Control: Ensures PMTs used in chemical plants, refineries, manufacturing, and power generation meet stringent accuracy and reliability requirements under varied environmental and operational conditions.

• Machinery Monitoring: Applies to transmitters measuring parameters like temperature, pressure, flow, and level in heavy machinery and industrial equipment.

• Quality Assurance and Compliance: Supports manufacturers and end-users in verifying that transmitters conform to international standards for performance, safety, and electromagnetic compatibility.

• Calibration Laboratories: Provides standardized procedures for type testing and routine calibration checks to maintain instrument traceability and certification.

• Digital Transmitter Testing: Includes throughput testing to verify digital communication performance, crucial for modern smart transmitter integration in automation systems.
