ASTM D1230: which instrument fits and how to decide

The 45 Degree Flammability Tester (TNG1062) is the appropriate instrument for compliance with ASTM D1230, as it meets the required specifications for flammability testing of plastics.

Selection Criteria for ASTM D1230 Compliance

When selecting an instrument for ASTM D1230, it is essential to focus on the specifications that directly relate to the test method's requirements. The standard mandates precise control over ignition time, flame height, and sample dimensions. The TNG1062 model provides these critical parameters with high accuracy, ensuring reliable and repeatable test results. The ignition time of (1 ± 0.05) s aligns with the standard's requirement for consistent ignition, which is crucial for accurate flammability assessment. Additionally, the flame height of 16 mm, which is adjustable, allows for precise control over the flame exposure, ensuring that the test conditions are met as specified. These features are fundamental in achieving the desired test outcomes and maintaining compliance with ASTM D1230.

Instrument Specifications and Their Relevance to ASTM D1230

The TNG1062 model includes several specifications that are directly relevant to the ASTM D1230 test method. The time display and accuracy of 0 ~ 999.9 s with 0.1 s resolution ensure that the ignition and burn times can be measured with high precision. This is essential for determining the flammability characteristics of the material under test. The sample dimension of 150 * 50 mm is another key specification, as it matches the standard's requirement for sample size, ensuring that the test is conducted under uniform conditions. The distance from the nozzle to the specimen of 8 mm is also critical, as it ensures that the flame is applied at the correct height, which is necessary for accurate measurement of the burn time and flame spread.

Instrument Model and Specification Verification

The TNG1062 model is specifically designed for flammability testing and includes all the necessary specifications to meet the requirements of ASTM D1230. The dimension of the holder, with an outside size of 170 * 101 mm and an inside size of 152 * 38 mm, ensures that the specimen is positioned correctly during the test. The adjustable flame height of 16 mm allows for fine-tuning the test conditions to match the standard's specifications. These specifications are not only essential for meeting the standard but also for ensuring the reliability and reproducibility of the test results. By adhering to these specifications, the TNG1062 model provides a robust solution for flammability testing in compliance with ASTM D1230.
