IEC 115 Application of Measurement Uncertainty to Conformity Assessment Activities in the Electrotechnical Sector

    IEC 115 Introduction

    Measurement results during testing, calibration, and inspection are crucial in making conformity assessment decisions in the electrotechnical industry. Nonetheless, every measure is associated with some degree of uncertainty, the presence of which may affect the compliance judgments if it is not considered. IEC 115 provides principles and methods of practical use of measurement uncertainty in conformity assessment. The standard assists in fair and consistent decisions of compliance, assists in harmonization between laboratories and certification bodies, and enhances confidence in test results to try to obtain regulatory approval, certification, and market access.

    Get Certified IEC 115 for Reliable Conformity Assessment Decisions

    Certification in accordance with IEC 115 shows that measurement uncertainty is appropriately considered in compliance tests by the conformity assessment activities. The certification increases credibility, aids in the accreditation requirements, and increases trust in the test reports and certification decisions. Implementation of IEC 115 practices lessens the disagreements, boosts transparency, and harmonizes the electrotechnical conformity assessments with the international best practices.

    IEC 115 Requirements and Decision Rules

    Measurement Uncertainty EvaluationQuantification of uncertainty associated with test results
    Decision RulesDefined criteria for acceptance or rejection, considering uncertainty
    Compliance StatementsClear reporting of conformity decisions
    Risk ConsiderationControl of false acceptance and false rejection risks
    DocumentationTraceable records of uncertainty evaluation and decisions
    ConsistencyUniform application of decision rules across assessments

    Scope of IEC 115

    • Refers to conformity testing within the electrotechnical industry. 
    • Includes the testing, calibration, inspection, and certification activities. 
    • Eradicates the use of measurement uncertainty in compliance. 
    • Favours laboratories, certification agencies, and regulators. 
    • Improves the transparency and conformity statement consistency. 
    • Conformity to international standards of accreditation and quality.

    IEC 115 Equipment and Sample Preparation

    Specimen PreparationPrepare test specimens according to applicable electrotechnical test standards without altering measured characteristics
    Specimen DetailUse representative products, components, or systems intended for conformity evaluation
    Specimen SizeSpecimen size depends on the applicable test method and product type under assessment

    Applications of IEC 115

    • Assessment of electrotechnical products. 
    • Decision-making in certification and regulatory compliance. 
    • Reporting and accredited laboratory testing. 
    • Checking and examination processes. 
    • Market surveillance and product approval. 
    • Compliance decision-making based on risk. 
    • Borderline compliance case resolution.

    IEC 115 Common Challenges and Troubleshooting

    The main issues, such as the lack of consistency with decision rules, ineffective estimation of measurement uncertainty, and ambiguous compliance statements, are common. Distortion of uncertainty margins may cause conflicts between certification bodies and manufacturers. The solution to these challenges includes the implementation of standardized uncertainty evaluation procedures, setting clear acceptance rules, and recording decision rules clearly.

    IEC 115 Technique Process, and Data Collection

    It is done by measuring the given electrotechnical parameter, assessing the corresponding measurement uncertainty, and using specified decision rules to evaluate conformity. The results of tests, uncertainty elements, confidence intervals, and results of the decision are also considered as data within the scope of data collection. Good documentation is used to guarantee traceability and repeatability of the conformity assessments.

    IEC 115 Analysis Results and Interpretation

    The assessments performed by IEC 115 guide interpreter measurement results concerning the specification limits, and taking uncertainty into account. A conforming outcome verifies that the measured value, along with the uncertainty value, meets the requirements at acceptable levels of risk. Non-compliance implies that the results are above the allowed amounts or within the grey area that needs additional review or testing.

    IEC 115 Problem & Solution

    Problem: When compliance decisions are made on the basis of measured values alone, there will be inconsistent or controversial conformity.

    Solution: IEC 115 Capsulates measurement uncertainty in the decision-making process, which guarantees equitable, uniform, and technologically warranted conformity tests.
