– Outlines fundamental concepts, common definitions, and general test setup constraints.
Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions.
The technical frameworks of the standard remain highly relevant across the industry. They are integrated globally through regional standards bodies, including CENELEC in Europe (EN 61298-2) and GOST R in the Eurasian economic region (ГОСТ Р МЭК 61298-2).
The standard is divided into logical sections. Here is what each part covers: iec 612982
But Vendor B's data sheet includes statements like: "Tested according to IEC 61298-1 through -5. Reference accuracy: ±0.1% at 20°C. Additional temperature error: ±0.02% per 10°C. Long-term drift: 0.1% per year." Vendor A simply says "high accuracy."
To execute a valid IEC 61298-2 evaluation, tests must be performed in a highly controlled laboratory environment. Standard Reference Conditions
Testing industrial instrumentation under arbitrary field conditions makes objective comparison impossible. A flow meter tested in an unconditioned, humid warehouse will register different drift patterns than one tested in an air-conditioned laboratory.
: To design reproducible test plans that ensure results are comparable across different facilities. Procurement Teams I can provide specialized testing templates or clarify
While other parts of the standard focus on general considerations or environmental effects, . It outlines the exact methods required to determine how an instrument behaves when external variables (like temperature, humidity, and supply voltage) are kept strictly constant. The Core Objective: Establishing the Baseline
: Checks insulation resistance, dielectric strength, and power or air consumption levels. iTeh Standards Who Uses It? Manufacturers
, ensuring the device maintains its performance over its operational life. Standardized Reporting
The global standard outlines the rigorous procedures required to evaluate the performance of industrial process measurement and control devices under standardized reference conditions . Maintained by the International Electrotechnical Commission (IEC) , specifically Subcommittee 65B (Devices and process analysis), this framework ensures that hardware from different manufacturers can be compared objectively using repeatable benchmark testing. Whether dealing with analogue or digital instruments, adhering to this standard allows automation engineers to quantify baseline accuracy, structural reliability, and long-term signal drift. 1. Scope and Core Objectives The technical frameworks of the standard remain highly
How much does the performance "wander" over a long period or right after starting up? Key Chapters (Sections) Scope
Its strength lies in systematic influence testing and rigorous uncertainty control . However, it is obsolete in parts (EMC references, missing reliability) and incomplete for digital, wireless, or safety-related devices.
: Simplifies compliance testing, speeds up time-to-market, and offers globally recognized engineering proofs.
