The method is applicable to papers and boards having air permeances between1\u00d710-2~1\u00d710\u00b2um\/\uff08Pa.S\uff09. The method is unsuitable for rough surfaced papers and boards, such as creped and corrugated papers, which cannot be securely clamped to avoid leakage.<\/p>\n

Air permeance:\u00a0<\/strong><\/p>\n

Air permeance is the mean flow of air through unit area under unit pressure difference in unit time, under specified conditions.<\/p>\n

Air permeance is expressed in micrometres per pascal second [1 \u03bcm\/(Pa\u00b7s)=1mL\/(m\u00b2\u00b7Pa\u00b7s)].<\/p>\n

2. Advantages of the TQD-01:<\/h2>\n

High resolution
\nUses a classic spectrometer principle
\nCan test flammable, toxic, and explosive substances
\nHas a large temperature range<\/p>\n

3. Elv<\/h2>\n

Clamping a test piece between two airtight circular gaskets of known dimensions, with the absolute air pressure on one side of the test area of the test piece equivalent to atmospheric pressure and the difference in pressure between the two sides of the test piece maintained at a small but substantially constant value during the test. Determination of the flow of air through the test area in a specified time.<\/p>\n
