ThisInternational Standard deals with fine ceramics.ThisInternational Standard specifies a test method for the determination of theself-cleaning performance of materials that contain a photocatalyst or havephotocatalytic films on the surface, and which ar

This standard is issued under the fixed designation C813; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last re

1. This testmethod measures the angle of contact when a drop of liquid is applied to thesurface of a specimen of paper.2. Themeasurement of both the initial angle of contact and the angle of contact aftera defined elapsed period of time may be measured.3.

1. This testmethod measures the contact angle of a test liquid in contact with a flatspecimen of a film or a paper substrate under specified test conditions. Thistest method may be used with any liquid of interest which is compatible withthe equipment use

1. This test methodcovers measurement of the contact angle of water droplets on corona-treatedpolymer film surfaces. NOTE 1—There is no similar or equivalent ISO standard.2. The values statedin SI units are to be regarded as the standard. The values given

1. This guide presents some generally acceptedlaboratory methodologies that are used for determining the corrosivity of crudeoil.2. This guide does not cover detailed calculations andmethods, but rather a range of approaches that have found application in

1. In this method (1-3), the contact anglebetween air and liquid on a paper surface is taken as a measure ofthe resistance of thepaper surface to wetting by the liquid.2. The initial angleof contact or initial wettability is considered to be a measure of

This International Standard specifies a ring method for the determination of the surface tension of polymer dispersions and rubber latices (natural and synthetic). The method is valid for polymer dispersions and rubber latices with a viscosity less than 2
