ASTM D1230 testing: the specifications that decide the fit

The 45 Degree Flammability Tester (TNG1062) is designed to meet the requirements of ASTM D1230 by providing precise control over critical parameters such as ignition time and flame height.

Understanding Specification Tables

Reading a specification table is essential for ensuring that an instrument meets the necessary standards for testing. For the TNG1062, the "Ignition time" specification is listed as "(1 ± 0.05) s". This value is crucial because it ensures that the ignition occurs at a consistent and controlled interval, which is necessary for accurate and repeatable test results as required by ASTM D1230. Another important specification is "Flame height," which is set at "16 mm, adjustable." This adjustable height allows the user to conform to the specific flame height requirements of the standard, ensuring that the test conditions are consistent and reliable.

Key Specifications and Their Role in Testing

The "Time display and accuracy" specification for the TNG1062 is "0 ~ 999.9 s, 0.1 s." This high level of precision in time measurement is vital for accurately timing the ignition and flame propagation phases of the test. The ability to measure time in increments of 0.1 seconds ensures that the test results are both accurate and reproducible, which is a fundamental requirement of ASTM D1230. Additionally, the "Distance from nozzle to specimen" is specified as "8mm," which is a critical parameter that ensures the flame is applied at the correct distance from the specimen, maintaining the integrity of the test conditions.

Ensuring Compliance with ASTM D1230

The "Sample dimension" of the TNG1062 is "150 * 50 mm," which aligns with the standard's requirements for sample size. This ensures that the samples used in testing are of the correct dimensions, which is essential for the validity of the test results. The "Dimension of holder" is "outside 170 * 101 mm, inside 152 * 38 mm," which is important for securely holding the sample in place during testing, preventing any movement that could affect the results. By adhering to these specifications, the TNG1062 ensures that all tests conducted are in compliance with ASTM D1230, providing reliable and consistent data for quality control and safety assessments.
