AATCC 195: which instrument fits and how to decide

The Moisture Management Tester (TNG1050) is a suitable instrument for compliance with AATCC 195, as it meets the required specifications for testing moisture management in textiles.

Matching Instrument Specifications to AATCC 195 Requirements

AATCC 195 outlines the procedures for determining the moisture management properties of textiles, which is essential for assessing how quickly a fabric can absorb and release moisture. When selecting an instrument to perform this test, it is critical to ensure that the device's specifications align with the method's requirements. The Moisture Management Tester (TNG1050) is specifically designed for this purpose, and its specifications directly support the testing procedures outlined in AATCC 195.

One key specification of the TNG1050 is its Test Solution Conductivity, which is set at 16 mS ± 0.2 mS. This value is crucial because AATCC 195 requires the use of a specific conductivity range to ensure consistent and accurate results. The precise control of conductivity allows for reliable measurement of moisture transfer, which is fundamental to the test's validity. Additionally, the Power Supply specification of 110V~23, 50Hz/60Hz ensures that the instrument can operate in a wide range of environments, making it suitable for various laboratory setups that may use different electrical standards.

Instrument Software and Interface Capabilities

The Analysis Software offered with the TNG1050 plays a vital role in data interpretation and reporting, which is necessary for compliance with AATCC 195. The software enables users to process test results efficiently and generate reports that meet the standard's documentation requirements. Furthermore, the Interface specification of USB 1.1/2.0 allows for seamless data transfer to computers, facilitating easy integration with laboratory information systems and ensuring that results are accurately recorded and stored.

Environmental Conditions and Operational Stability

The Operation Temp & R. H. specification of the TNG1050, which is 18°C to 40°C, 20% to 80% (non-condensing), is essential for maintaining consistent test conditions. AATCC 195 requires that environmental factors be controlled to prevent any interference with the moisture transfer process. The specified temperature and humidity range ensures that the instrument can operate reliably under standard laboratory conditions, thus supporting the accuracy and reproducibility of test results.

Pump On Time and Test Precision

The Pump On Time specification of the TNG1050, which is 20 sec, contributes to the precision of the test. This parameter ensures that the test solution is applied consistently to the fabric sample, which is critical for obtaining reliable moisture management data. The controlled application time helps maintain the integrity of the test process, aligning with the procedural requirements of AATCC 195.
