ISO 105 testing: the specifications that decide the fit

The TNG1029 Crockmeter, TNG1027 WashTrue Washing Fastness Tester, TNG1025 Scorch Tester, and TNG1034 Perspiration Tester are all designed to meet the requirements of ISO 105 for colour fastness testing.

Understanding Specification Tables

Reading a specification table is essential for ensuring that an instrument meets the required standards. For instance, the TNG1029 Crockmeter specifies a "Type of Crockmeter" as "Electronic Crockmeter," which indicates that the instrument uses electronic controls to ensure consistent and accurate testing. This is crucial for meeting ISO 105 standards, as it ensures that the test results are reliable and repeatable. Another important specification is the "Rubbing head" size, which is "16 mm." This dimension is critical because it ensures that the rubbing force is applied uniformly, which is necessary for accurate colour fastness measurements.

Key Specifications and Their Role in Testing

The TNG1027 WashTrue Washing Fastness Tester has a "Temperature setting range" of "Normal temperature (>0°C)~ 95°C." This wide range allows the instrument to simulate various washing conditions, from normal to high-temperature cycles, which is essential for testing the durability of fabrics under different environmental conditions. Additionally, the "Heating Rate" is specified as "1.5±0.5℃/min," which ensures that the temperature increases at a controlled rate, maintaining the integrity of the test process and aligning with the ISO 105 requirements.

Supporting Standards with Instrument Specifications

The TNG1025 Scorch Tester includes "Standard Accessories:" such as "Insulation cotton," which is necessary for protecting the test samples from direct heat exposure. This accessory ensures that the test conditions are consistent and that the results are not influenced by external factors. The "Length: 460 mm" and "Width: 310 mm" specifications for the TNG1034 Perspiration Tester are important because they define the size of the testing chamber, ensuring that the perspiration solution is evenly distributed and that the test samples are exposed to the correct amount of moisture. These specifications are vital for meeting the ISO 105 standards and ensuring that the test results are accurate and reliable.

Ensuring Compliance with ISO 105

Each instrument's specifications are carefully designed to support the testing procedures outlined in ISO 105. The TNG1029 Crockmeter's "Vertical pressure" of "9N+/-10%" ensures that the force applied during the rubbing test is consistent, which is critical for obtaining accurate colour fastness measurements. Similarly, the TNG1034 Perspiration Tester's "Perspiration:" specification of "AATCC 15" aligns with the standard methods for testing colour fastness to perspiration, ensuring that the test conditions are standardized and repeatable. By adhering to these specifications, the instruments provide reliable and consistent results, which are essential for compliance with ISO 105.
