The test method is only one of several available for the measurement of tack and is not recommended for the specification of end use products. Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. D1804 materials which absorb the test liquid under the specified test conditions, the rate of change of the contact angle as a function of time may be significant, and may be determined using procedures described in this test method.

C1084 such cases, test liquids other than reagent water, including writing and printing inks, or organic liquids or mixtures of organic liquids may be used as the test liquid upon prior agreement of those involved in the testing, provided the liquid is compatible with the equipment used.
This test method measures the contact angle of a test liquid in contact with a flat specimen of a film or a paper dd1084 under specified test conditions. This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus.
These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc. Standard Practice for Conducting Creep Tests of Metal-to-Metal Adhesives This practice covers the determination of the amount of creep of metal-to-metal adhesive bonds due to the combined effects of temperature, tensile shear stress, and time.
It is also possible to evaluate the absorptive properties of a surface, as the remaining liquid volume on top of the specimen surface is measured as a function of time.

Hand-held micrometer for measuring coatings applied to plane rigid surfaces. This test method covers the determination of the comparative peel or stripping characteristics of adhesive bonds when tested on standard-sized specimens and under defined conditions of pre-treatment, temperature and testing machine speed.
This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. The test method may be used with any liquid of interest, which is compatible with the equipment used, particularly with regard to liquid viscosity, tackiness, and vapour pressure evaporation.
This test method is applicable to self-levelling and non-sag grades of sealant. Two types of apparatus for measuring the contact angle using the procedure in this test method are described. This test method covers the non-destructive measurement of the dry film thickness of electrically nonconductive coatings applied over a nonferrous metal base using commercially available eddy current instruments.
Other liquids including printing inks, writing inks, adhesives, oils, and coating materials may be used upon agreement of those involved in the testing being done. It covers the measurement of both the initial angle of contact and the angle of contact after a defined elapsed period of time may be measured.
This test method covers the measurement of Krebs Unit KU viscosity to evaluate the consistency of paints and related coatings using the Stormer-type viscometer. This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces.
This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions.
This practice covers the determination of the amount of creep of metal-to-metal adhesive bonds due to the combined effects of temperature, tensile shear stress, and time.
This practice covers two procedures applicable to all adhesives having a relatively short working life. These test methods r1084 the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method.
Test periods depend upon the reasonable life expected from the material in service. This test method covers the detection of the presence of hydrophobic non-wetting films on surfaces and the presence of hydrophobic organic materials in processing ambients.

A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D Conditions are specified for the testing of a wide range of papers considered to f1084 of low absorbance or non-absorbent, including release papers, sized, coated, or un-sized papers designed for printing, writing, wrapping, and similar tasks where the paper surface interaction with aqueous or solvent based inks or other aqueous or non-aqueous liquids is important.
A standard liquid ink for making measurements is described.
When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants. This test method covers measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball and is most appropriate for low-tack adhesives. Two methods are described as follows:. This test method is not applicable to coatings that will be readily deformable under the load of the measuring instruments, as the instrument probe must be placed directly on the coating surface to take a reading.
Where test liquids other than reagent water are used, the actual liquid used is reported. Limitations include the ability to accurately determine the amount of paint solids deposited on the part and the capability of accurate measurement of the amount of paint sprayed.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature. This test method covers a procedure for the determination of the tack-free time property of single- and multi-component elastomeric sealants commonly used for sealing, caulkingand glazing in buildings and related construction.
