Applications
Measurement of the thermal resistance and the evaporative resistance, under steady-state conditions, of fabrics, films, coatings, foams, and The quilt,including multi-layer assemblies, for use in Clothing production.
Standards
ISO 11092: International standard for "Textiles — Physiological effects — Measurement of thermal and water-vapour resistance under steady-state conditions" (directly governs its core function of testing thermal/evaporative resistance; product’s separated climate chamber and stable wind speed meet its strict environmental control requirements).
JIS L1096-2010: Japanese Industrial Standard "Textiles — Test methods for colour fastness" (extends to Breathability/Moisture permeability testing; product’s precise water supply and stable air flow support its moisture permeability assessment).
ASTM D6701-16Standard Test Method for Determining Water Vapor Transmission Rates Through Nonwoven and Plastic Barriers.
ASTM D1518-2014: American Society for Testing and Materials standard "Textiles — Thermal and evaporative resistance" (specifies test methods for thermal properties; product’s automatic water system and stabilized wind speed ensure compliance with its precision criteria).
ASTM F1868-09/02: ASTM standards for "Thermal and Evaporative Resistance of Clothing Materials" (focuses on protective garment testing; product’s skin-simulating design and separated test/climate chamber meet its demand for realistic human body contact conditions).
BS8515: British Standard "Code of practice for the design of buildings and their approaches to meet the needs of disabled people" (indirectly relevant for material performance in humid environments; product’s stable moisture control supports material assessment in such applications).
GB/T 11048: Chinese National Standard "Textiles — Determination of thermal resistance" (defines domestic textile thermal resistance test parameters; product’s design aligns with its requirement for accurate, repeatable measurements).

Test Procedures
Sample Preconditioning: Place specimens under standard atmospheric conditions for humidity conditioning to ensure material stability.
Sample Cutting: Use the dedicated template to cut “L”-shaped or square specimens of specified dimensions (as prompted by the software).
Sample Placement: Lay the specimen flat on the test platform, ensuring no wrinkles and that the grain direction complies with standard requirements.
Test Initiation: Enter sample information in the software interface and click “Start.” The instrument will sequentially perform compression, bending, surface friction, and heat exchange tests.
Data Generation: Upon test completion, the system automatically calculates various tactile metrics (e.g., Smoothness, Softness, Warmth).
Result Export: Generate objective tactile radar chart reports for convenient data storage or cross-team sharing.
Maintenance Information
Sensor Protection: Pressure and heat flux sensors are highly precise. Never press directly with fingers or touch sensing surfaces with sharp objects.
Cleaning and Maintenance: After each test, use an air pump or soft, lint-free cloth to remove fiber debris and dust from the test platform surface.
Regular Calibration: It is recommended to calibrate pressure and heat flow every six months using the included standard blocks to ensure data accuracy.
Software Updates: Regularly check for driver and algorithm updates to obtain the latest tactile rating models.
