There appears to be a slight typo in your query. IEC 61298-2 is an international standard titled "Process measurement and control devices - General methods and procedures for evaluating performance - Part 2: Tests under reference conditions". It does not specifically govern "solid posts," which are typically categorized under insulator standards like IEC 60273 or IEC 60168. Overview of IEC 61298-2
This standard specifies general methods for conducting tests and reporting the functional and performance characteristics of process measurement and control devices. It applies to both analogue and digital devices.
Primary Focus: Performance evaluation specifically under reference conditions (standardized laboratory environments).
Key Performance Metrics: Covers accuracy-related factors including dead band, hysteresis, non-linearity, and repeatability.
Dynamic Behavior: Includes testing procedures for frequency response, step response, and dead-time characteristics.
Functional Characteristics: Evaluates physical properties such as input resistance, insulation resistance, and power or air consumption. Solid Core Post Insulators (Potential Intent)
If you were looking for information on solid core post insulators (often called "solid posts" in substation engineering), these are typically covered by different standards:
IEC 60273: Characteristics of indoor and outdoor post insulators for systems with nominal voltages greater than 1,000 V.
IEC 60168: Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal voltages greater than 1,000 V. iec 612982
Technical Specs: These insulators are rated from 1 kV up to 420 kV and are used in substation busbar protection zones. SOLID CORE POST INSULATORS FOR SUBSTATIONS
IEC 61298-2 outlines general methods for evaluating the performance of process measurement and control devices under reference conditions, emphasizing accuracy metrics like hysteresis and repeatability. A compliant report must document specific test results, such as measurement cycles and drift analysis, often utilizing structures from the IEC 61298 series.

IEC 61298-2 , titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions," provides a standardized framework for evaluating the performance of industrial instrumentation. It ensures that performance data for analog and digital devices is reliable and comparable by testing them under controlled, ideal conditions. IEC Webstore Key Evaluation Areas
The standard details procedures for assessing several critical performance metrics: iTeh Standards
Guidelines for testing, data handling, and error curve generation. Dynamic Behavior: Procedures for step input and frequency response tests. Functional Characteristics:
Evaluation of power consumption, output signal ripple, and insulation resistance. Methods for measuring long-term and start-up drift. iTeh Standards Context and Applications
IEC 61298-2 (Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions) is a key international standard for assessing industrial instrumentation. It establishes rigorous, standardized methods to evaluate the accuracy and functionality of both analog and digital devices (sensors, actuators) under stable reference conditions. 1. Scope and Purpose
The standard ensures reliable, comparable performance data across manufacturers. There appears to be a slight typo in your query
Applicability: Covers devices with defined input/output variables.
Exclusions: Typically excludes Process Measurement Transmitters (handled by IEC 62828).
Reference Conditions: Tests occur under strictly defined "normal" conditions (temperature, voltage, etc.) to establish a performance baseline. 2. Key Performance Indicators (KPIs) The standard defines procedures for measuring:
Accuracy Metrics: Measured error, non-linearity, hysteresis, and non-repeatability. Dynamic Behavior: Step response, rise time, and dead-time.
Functional Checks: Insulation strength, power/air consumption, and long-term drift. IEC 61298-2:2008
It seems you are asking for a deep review of IEC 61298, but the number appears slightly off. The correct standard is likely IEC 61298 (Parts 1–5), which covers Process measurement and control devices – General methods and procedures for evaluating performance.
However, if you meant IEC 61215 (terrestrial photovoltaic (PV) modules – design qualification and type approval) or IEC 61850 (power utility automation), please clarify. I will proceed with a deep review of IEC 61298 as requested.
IEC 61298 (parts 1–5) specifies uniform methods for testing the performance of process measurement and control devices (e.g., transmitters, sensors, controllers, valves with positioners). It applies to devices with analog or digital output signals and covers testing under influence quantities (temperature, humidity, vibration, supply variations, etc.). Scope & Purpose IEC 61298 (parts 1–5) specifies
The standard is foundational for manufacturers, calibration labs, and end-users to compare devices from different suppliers under repeatable conditions.
IEC 61298 is a multipart international standard that specifies uniform methods for evaluating the performance of any process measurement or control device. These devices include:
The standard does not prescribe pass/fail criteria (e.g., "must be 0.5% accurate"). Instead, it defines how to test a device to determine its performance characteristics, such as accuracy, repeatability, hysteresis, drift, and environmental sensitivity.
Think of it as the "recipe book" for instrument testing. It ensures that if Company A tests a pressure gauge using IEC 61298-1, Company B in another country will be able to reproduce and trust the results.
What good is a test if the results are illegible? Part 5 specifies how to report findings in a standardized format. A compliant report includes:
This part ensures regulatory bodies, auditors, and customers can compare data from different suppliers without guessing.
Myth 1: "IEC 61298 is only for manufacturers."
False. End users use it for incoming inspection, troubleshooting, and calibration interval justification. Many large oil & gas companies (e.g., Shell, ExxonMobil) reference IEC 61298 in their internal engineering standards.
Myth 2: "Compliance means the device is good for my process."
No. The standard only tells you how to test; it does not set performance thresholds. You still must define your required accuracy (e.g., 0.5% for inventory, 0.05% for custody transfer).
Myth 3: "All 'IEC-tested' instruments are comparable."
Only if they cite the specific part and test conditions. A manufacturer claiming "tested to IEC 61298" without stating the part number and reference conditions is offering little value. Always ask: Which part? What influence quantities? Under what environmental range?
