AATCC 92 testing: the specifications that decide the fit

The Scorch Tester (Sublimation Fastness Tester) model TNG1025 is designed to meet the requirements of AATCC 92 for sublimation fastness testing.

Understanding Specification Tables

When reviewing a specification table for a testing instrument, it is essential to identify key label/value pairs that directly influence the accuracy and reliability of test results. For the TNG1025 Scorch Tester, two critical specifications are the standard accessories and the dimensions of the testing area. The standard accessories include insulation cotton, which is used to protect the test sample from direct heat exposure and ensure uniform heat distribution. This is crucial for maintaining consistent test conditions as required by AATCC 92. Additionally, the dimensions of the testing area are specified as Length: 460 mm and Width: 310 mm. These dimensions are important because they define the area over which the heat is applied, ensuring that the test sample is subjected to the correct heat intensity and duration as outlined in the standard.

Instrument Specifications and Their Role in Testing

The TNG1025 Scorch Tester is equipped with a range of specifications that are essential for accurate testing. One of the key specifications is the power supply, which is listed as 220 V, 50 Hz. This ensures that the instrument operates within the required electrical parameters, providing stable and consistent performance during testing. Another important specification is the use of AATCC NO.10A multi-fiber cloth, which is a standard material used in color fastness testing. This cloth is designed to mimic the behavior of various fibers under heat, allowing for the accurate assessment of sublimation fastness. The use of this specific cloth ensures that the test results are comparable across different samples and laboratories, adhering to the AATCC 92 standard.

Compliance with AATCC 92 Standards

The TNG1025 Scorch Tester is specifically designed to comply with the AATCC 92 standard, which outlines the procedures for testing sublimation fastness. The inclusion of insulation cotton as a standard accessory ensures that the test sample is protected from direct heat, which could otherwise lead to inaccurate results. The dimensions of the testing area, 460 mm in length and 310 mm in width, are critical for ensuring that the heat is applied uniformly across the sample. This uniformity is essential for obtaining reliable and reproducible results. By adhering to these specifications, the TNG1025 Scorch Tester provides a robust and accurate method for assessing sublimation fastness, meeting the rigorous requirements of AATCC 92.
