ASTM D746 Low Temperature Impact Post Chemical Exposure Laboratory Testing Service: A Comprehensive Guide

Standard-Related Information

ASTM D746 is a widely recognized standard for evaluating the low temperature impact resistance of plastics and other materials after exposure to chemicals. The standard, developed by ASTM International (formerly known as the American Society for Testing and Materials), provides a standardized method for assessing the durability and reliability of materials under extreme conditions.

The legal and regulatory framework surrounding this testing service is governed by various international and national standards, including:

  • ISO 4893-1:2017 - Plastics - Determination of the effect of light on plastics types - Part 1: General guidance

  • ASTM D1435 - Standard Practice for Testing Flexible Barrier Materials

  • EN 45545-2:2015 - Railway applications - Fire protection on railway vehicles - Part 2: Global fire protection requirements and system design

    • International standard development organizations, such as ISO (International Organization for Standardization), ASTM International, and IEC (International Electrotechnical Commission), play a crucial role in developing and updating standards to ensure consistency and comparability across the globe.

    Standards evolution and updates are essential to reflect advancements in technology, changes in regulatory requirements, and emerging risks. The process involves:

    1. Research and development

    2. Consensus-building among experts

    3. Drafting and reviewing of new or revised standards

    4. Approval by standard development organizations

    Specific standard numbers and their scope include:

  • ASTM D746: Standard Practice for Low-Temperature Impact Resistance of Plastics and Electrical Insulating Materials After Exposure to Chemicals

  • ISO 4893-1:2017 - Determination of the effect of light on plastics types - Part 1: General guidance

    • Compliance with these standards is essential for various industries, including:

  • Automotive

  • Aerospace

  • Construction

  • Packaging

  • Medical devices

    • Standard Requirements and Needs

    ASTM D746 Low Temperature Impact Post Chemical Exposure testing is necessary to ensure the safety and reliability of materials under extreme conditions. This test helps manufacturers and regulatory bodies assess the risk of material failure due to low temperatures and chemical exposure.

    The consequences of not performing this test can be severe, including:

  • Material failure leading to accidents or injuries

  • Loss of product certification or market access

  • Non-compliance with regulations and standards

    • This testing is particularly important for industries that require high levels of safety and reliability, such as aerospace and medical devices. The risk factors associated with this testing include:

  • Temperature extremes (below -20C)

  • Chemical exposure (various solvents and fuels)

    • Test Conditions and Methodology

    The ASTM D746 test involves the following steps:

    1. Sample preparation: Specimens are cut to size, cleaned, and dried according to standard procedures.

    2. Testing equipment: A low-temperature impact testing machine is used to simulate the impact of a projectile on the specimen at a temperature below -20C.

    3. Chemical exposure: The specimens are exposed to various chemicals, including solvents and fuels, for a specified duration.

    4. Impact testing: The specimens are subjected to impact testing after chemical exposure.

    The testing parameters and conditions include:

  • Temperature: -30C (or lower)

  • Chemical exposure: Various solvents and fuels

  • Duration: 24 hours or longer

  • Impact speed: 2.5 m/s

    • Measurement and analysis methods involve:

  • Visual inspection of specimens for cracks, breaks, or other damage

  • Determination of impact resistance using a standard procedure

  • Analysis of test data to determine material performance under extreme conditions.

    • Test Reporting and Documentation

    Test results are documented in a detailed report, which includes:

    1. Test parameters and conditions

    2. Sample preparation procedures

    3. Testing equipment and instruments used

    4. Results of visual inspection and impact testing

    5. Analysis of test data

    The report format and structure follow the guidelines specified by ASTM International.

    Why This Test Should Be Performed

    Performing this test provides numerous benefits, including:

    1. Risk assessment and mitigation: Identify potential material failure points under extreme conditions.

    2. Quality assurance and compliance: Ensure product safety and reliability meet regulatory requirements.

    3. Competitive advantages: Demonstrate commitment to quality and safety in the marketplace.

    4. Cost savings: Reduce the likelihood of costly repairs or replacements due to material failure.

    5. Legal and regulatory compliance: Stay compliant with relevant standards and regulations.
