Comprehensive Guide to BS 1881-208 Testing for Flexural Strength Laboratory Testing Service Provided by Eurolab

BS 1881-208 is a British Standard that specifies the methods of testing concrete, mortar, and other cement-based materials for their flexural strength. The standard is published by BSI (British Standards Institution) and is widely adopted across the construction industry in the UK.

Legal and Regulatory Framework

The standard is compliant with EU regulations and directives, including:

  • EU Directive 89/106/EEC on the approximation of laws, regulations, and administrative provisions of the Member States relating to construction products

  • EU Regulation (EU) No 305/2011 on Construction Products

    • In the UK, BS 1881-208 is referenced in the following documents:

  • BS EN 206:2006A2:2013, which specifies the requirements for concrete in the UK

  • BS 8500:2006A1:2012, which specifies the requirements for concrete testing in the UK

    • International and National Standards

    BS 1881-208 is harmonized with international standards, including:

  • ISO 1920-4:2009, which specifies the methods of testing concrete and mortar for their flexural strength

  • ASTM C348-16, which specifies the methods of testing concrete and masonry cylinders for compressive strength and flexural strength

    • In addition to BS 1881-208, other relevant standards include:

  • BS EN 12390-5:2009A1:2010, which specifies the requirements for testing hardened concrete

  • BS 4551:1978A1:2012, which specifies the methods of testing masonry for its compressive strength and flexural strength

    • Standard Development Organizations

    The development of standards is a collaborative effort between standard development organizations (SDOs), including:

  • BSI (British Standards Institution)

  • ISO (International Organization for Standardization)

  • ASTM (American Society for Testing and Materials)

    • These SDOs work together to develop, maintain, and publish international standards that are widely adopted across industries.

    Standard Evolution and Update

    Standards are reviewed and updated regularly to reflect advances in technology, changes in regulations, and new research findings. The frequency of standard updates varies depending on the industry and the specific standard.

    BS 1881-208 is a critical testing method for ensuring the quality and performance of concrete, mortar, and other cement-based materials. The test is required by regulatory bodies, such as:

  • Local authorities

  • Government agencies

  • Industry associations

    • Business and Technical Reasons for Conducting BS 1881-208 Testing

    The business and technical reasons for conducting BS 1881-208 testing include:

  • Ensuring compliance with regulations and standards

  • Verifying the quality and performance of materials

  • Reducing the risk of defects and failures

  • Enhancing product safety and reliability

  • Improving competitiveness through certification and accreditation

  • Supporting innovation and research development

    • Consequences of Not Performing this Test

    Failure to perform BS 1881-208 testing can result in:

  • Non-compliance with regulations and standards

  • Material defects and failures

  • Reduced product safety and reliability

  • Loss of business and revenue

  • Reputation damage and loss of customer trust

    • BS 1881-208 testing involves the following steps:

    1. Sample preparation: The test specimen is prepared according to the standard, which specifies the dimensions, shape, and surface finish.

    2. Testing equipment: The test is conducted using specialized equipment, including a flexural testing machine.

    3. Testing environment: The test is performed in an environmental chamber that maintains a controlled temperature (20C 1C) and relative humidity (50 10).

    4. Measurement and analysis: The deflection of the specimen is measured using a dial gauge or laser interferometer, and the flexural strength is calculated using the formula specified in the standard.

    5. Calibration and validation: The testing equipment and instruments are calibrated and validated regularly to ensure accuracy and precision.

    The test report includes:

  • Test specimen details

  • Testing conditions and parameters

  • Measurement and analysis results

  • Flexural strength calculation

  • Certification and accreditation statements

    • Interpretation of Test Results

    The interpretation of test results is critical in determining the quality and performance of materials. The standard specifies the criteria for assessing flexural strength, including:

  • Minimum required values

  • Acceptance and rejection limits

    • BS 1881-208 testing provides numerous benefits, including:

  • Compliance with regulations and standards

  • Verification of material quality and performance

  • Reduced risk of defects and failures

  • Improved product safety and reliability

  • Enhanced competitiveness through certification and accreditation

  • Support for innovation and research development
