PARAM® TQD-G1 Air Permeability Tester TQD-G1 is professionally designed for the determination of air permeability of decorating materials used in cars, e.g. polyurethane, nonwovens and other materials. Through the test, physical characteristics of materials could be controlled to meet practical application requirements. Professional Technology This instrument is designed according to the standard requirements of global automakers 2 test modes are available for customers: fix pressure difference to test flux and fix flux to test pressure difference High precision sensors of electronic airflow and air pressure to ensure the accuracy of test data The instrument is controlled by micro-computer, with LCD, menu interface and PVC operation panel, which is convenient for customers to operate or view test data Equipped with micro-printer and standard RS232 port for easy connection with PC and data transfer Test Principle Method A Providing a constant air flux going through the specimen vertically, the air permeability could be obtained by measuring the pressure difference. Method B Providing the constant pressure difference between two sides of the specimen, the air permeability could be obtained by measuring the air flux through specific area in the certain time. This instrument conforms to the multiple national and international standards: ISO 9237, ISO 4638, ISO 5636, GB/T 10655, GB/T 5453, GB/T 4689.22, GB/T 13764, ASTM D737, TAPPI T460, JIS P8117 Applications This instrument is applicable to the determination of: Decorating Articles of Cars Basic Applications Extended Applications Test the air permeability of car decorating materials, e.g. polyurethane, PVC, leather, textiles and non-woven materials Test the air permeability of elastic and porous polymer materials, e.g. Polymer Materials Test the air permeability of textiles, e.g. cloth and nonwovens Test the air permeability of leather Test the air permeability of paper materials, e.g. daily removable tissue and toil
