Description : The Gurley Model 4301 Permeometer measures the porosity or air-permeability of materials where air flow is an important characteristic relative to their use. These materials might be non-woven or woven textiles, filter and cloth felts, and some types of blotting, saturating and absorbent bag papers as well as meshes. Conform to TAPPI T-251, ASTM D-737, DATM 70.0-70 and ISO 5636/1.

Specifications :

• The Gurley Model 4301 Permeometer measures the porosity or air permeability of materials where air flow is an important characteristic relative to their use. These materials might be non-woven or woven textiles, filter and tissue papers, facial tissues, paper and cloth felts, some types of blotting, saturating and absorbent bag papers as well as wire meshes.
• The Permeometer is the standard instrument for measuring high levels of air-permeability or air-resistance as recommended in various test methods published by ASTM, TAPPI and ASA. Its unit of measurement is cubic feet of air per minute per square foot at 0.5 inches of water pressure drop.
• The Gurley Model 4301 is used throughout the textile and general manufacturing industries and is considered the instrument of choice due to its simplicity of loading samples, ease of use, portability and life expectancy in comparison to competitive models. Its procedure is non-destructive and its design allows the testing of long samples, up to six inches in from any edge.

Applications :

• To determine ability for material to pass air as a primary user requirement (such as parachute cloth or vacuum cleaner bags).
• To evaluate materials used as filters.
• Aid in determining coolness or warmth (as insulation values) in clothing.
• To predict probable coating penetration.
• To measure retention of filters, sizing or scratch after laundering or use.
• To aid in prediction of water-resistant properties.
• To measure the effect of treatments on porosity, density, nap or other material properties.
• Allows fast & easy quantitative measurement of variables in production not detectable by appearance or other methods.
• A non-destructive test to accurately delineate & quantify differences in materials and treatments.

Features :

• Quick & easy sample loading
• Rapid test cycle
• Excessive clamping pressure unnecessary
• Portable & rugged design
• Complies with TAPPI, ASTM, & ASA standards

Water absorptiveness of paper board or other materials is a function of various characteristics such as sizing, porosity, etc. The Gurley-Cobb sizing test can be used to test absorption or resistance to absorption of water, oil and other liquids.

This procedure determines the quantity of water absorbed by a sample of paper or other sheet material in a specified time and under standardized conditions. Other liquids such as ink, beverages, oil and water based solutions may be used instead of water. The standard area is one hundred square centimeters (cm2), into which 100cc of liquid are poured to reach a specific height of 1 cm. For smaller samples, proportionately smaller areas (25 and 10 cm2) can be tested.

The Gurley-Cobb Sizing Tester consists of a hollow metal cylinder or ring (100, 25 or 10 cm2 inside area); a metal base plate with a clamping device to hold the ring against the sample and a Neoprene mat. Neoprene gaskets also are supplied to seal off the cylinder when testing uneven materials where an ungasketed seal is difficult to maintain. A critical component of this test is a solid stainless steel roller having a smooth face 20cm wide and weighing 10.0+ 0.5kg.

Also required for the test are a 100ml graduated cylinder, a balance with sensitivity of 0.01g or better, blotting paper and a timer or stopwatch.
