This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing.
This test method covers the measurement of the wetting tension of a polyethylene or polypropylene film surface in contact with drops of specific test solutions in the presence of air. 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. 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.
Procedures A and C are not atsm for films less than 0. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions. The test method may be used with ashm liquid of interest, which is compatible with the equipment used, particularly with regard to liquid viscosity, tackiness, and vapour pressure evaporation.
Hand-held micrometer for measuring coatings applied to plane rigid surfaces. A standard liquid ink for making measurements is described.
This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used.
This asgm method covers the measurement of Krebs Unit KU viscosity to evaluate the consistency of paints and related coatings using the Stormer-type viscometer.
The minimum thickness required for Procedures B and D is a function of that required to enable removal of the sample as a free film.
ASTM D – 16 – Standard Test Methods for Viscosity of Adhesives
Test periods depend upon the reasonable life expected from the material in service. This test method is applicable to both gun and knife grades. 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.
The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions. 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.
This test method covers the determination of the comparative f1084 or stripping characteristics of adhesive bonds when tested on standard-sized specimens and under defined conditions of pre-treatment, temperature and testing machine speed.
For 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. This practice covers the determination of the amount of creep of metal-to-metal adhesive bonds due to the combined asstm of temperature, tensile shear stress, and time.
Two types of apparatus for measuring the contact angle using the procedure in this test method are described. This test method covers the determination of the creep properties of adhesives for bonding metals when tested on a standard specimen and subjected to certain conditions of temperature and tensile stress in a spring-loaded testing apparatus.

This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. These test methods apply to general plant production equipment and procedures. The conditions required in this test method specify reagent water as the test liquid when testing papers designed to be absorbent, such as absorbent tissue grades. When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature. Conditions are specified for the testing of a wide range of papers considered to be 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.
Additional instruments that can perform the procedure in this test method may also provide equivalent results.

This test method covers the determination of the tack-free time property of caulking compounds and sealants. The test method is applicable atsm those adhesives which form a bond of measurable strength rapidly upon contact with another surface and which can be removed from that surface cleanly, that is, without leaving a residue visible to the eye.
Two methods are described as follows:. In such cases, test liquids other than reagent water, including d1048 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 c1084 with the equipment used.
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. These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer.
Where test liquids other than reagent water are used, the actual liquid used is reported. This test method covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, and sstm liquid materials with the Ford-type efflux viscosity cup. This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products.
