Preparing for AATCC 8 testing: from method to instrument setup

The Crockmeter (TNG1029) is the recommended instrument for compliance with AATCC 8, as it meets all required specifications for colour fastness testing.

Confirm the Method Code

Before procurement, verify that the test method code AATCC 8 is the correct standard for your application. AATCC 8 specifies the evaluation of colour fastness to rubbing, and the Crockmeter (TNG1029) is explicitly designed for this purpose. Ensure that the method code is correctly referenced in your testing protocol to avoid misalignment with the standard.

Identify the Required Measuring Range

The Crockmeter (TNG1029) must be selected based on the expected colour fastness range of the materials being tested. The instrument's specifications include a rubbing head size of 16 mm, which is standard for AATCC 8 testing. This dimension ensures consistent contact pressure and surface area during the rubbing process, critical for accurate results. Additionally, the vertical pressure of 9N+/-10% is calibrated to match the force required by the standard, ensuring that the test simulates real-world conditions without over or under-stressing the sample.

Check the Published Specification Table

Review the published specifications of the Crockmeter (TNG1029) to confirm that all parameters align with AATCC 8 requirements. The rubbing stroke of 104 mm is a key specification that ensures the test cycle is completed over the correct distance, maintaining uniformity in the rubbing action. The counter function, which allows for 1 ~ 999,999 cycles and automatically stops, supports precise and repeatable testing, essential for meeting the standard's reproducibility criteria. The net weight of 11 kg is also important for installation and operation, ensuring the instrument is stable and secure during testing.

Request a Quotation

Once the method code, measuring range, and specifications are confirmed, request a quotation from the supplier. Ensure that the quotation includes the model number TNG1029 and all relevant specifications. This step helps ensure that the procurement process is aligned with the required standards and that the instrument will perform as expected in your testing environment.
