Published By Publication Date Number of Pages
TAPPI 2015-03-16 3
]]> This method describes a procedure for measuring water repellence of paper, paperboard, or combined board which has been treated to produce water repellence. This method can be used for a wide range of products, from sheets having only slight water repellence to sheets with wax sizings or coatings that have a high degree of water repellence.

This method is useful for sheets treated with such materials as a stearic chrome complex, polyvinylidine chloride, polyvinyl compounds, commercial varnishes, paraffin wax impregnations, and paraffin wax coatings. The sheet may be produced directly on the paper machine or subsequently coated.

The method is not practical for plastic extrusion coatings, heavily wax-coated, not certain curtain-coated grades which have a hard wax/resin type of coating, for which the test period becomes prohibitively lengthy.

Published By Publication Date Number of Pages
TAPPI 2015-05-06 3
]]> This method describes a procedure for testing grease repellency of flexible packaging materials. It is an accelerated test designed to measure the repellency and resistance of oil and grease penetration of fluorochemically treated flexible packaging materials.

This test is intended to supplement TAPPI T 454 "Turpentine Test for Voids in Glassine and Greaseproof Papers" and TAPPI T 507 "Grease Resistance of Flexible Packaging Materials."

Published By Publication Date Number of Pages
TAPPI 2015-04-01 4
]]> The object of this method is to determine paper opacity by measuring the ratio of the reflectance of paper backed by black and white using an instrument equivalent to the geometry of the TAPPI brightness measurement instrument. Approximate TAPPI opacity is measured by contrast ratio of the specimen reflectance backed by a black cavity to white backing of 89%. The term "approximate" is used to differentiate the TAPPI opacity measured with this procedure to the TAPPI opacity measured using an instrument that conforms to the measurement of opacity as specified in the geometry in T 425 "Opacity of paper (15/d geometry, illuminant A/2°, 89% reflectance backing and paper backing)."

Published By Publication Date Number of Pages
TAPPI 2021 4
]]> This method is suited for the numerical estimation of cleanliness for optical character recognition
(OCR) purposes of paper and paperboard in terms of the frequency of dirt, specks, or marks. For other dirt count methods, see TAPPI T 437 Dirt in Paper and Paperboard, TAPPI T 213 Dirt in Pulp, and TAPPI T 563, Equivalent Black Area (EBA) and Count of Visible Dirt in Pulp, Paper and Paperboard by Image Analysis.
This method may be used in applications where the number of specks per unit area rather than the equivalent black area is required.
In this method, each dirt speck is counted individually regardless of size, shape, or color. This differs from TAPPI T 437 where the dirt is expressed in terms of equivalent black area and is a function of its color, contrast with the background, and shape.
