This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. D104 standard liquid ink for making measurements is described.
ASTM D – 16 – Standard Test Methods for Viscosity of Adhesives
This test method measures the contact angle of a test liquid in contact with a flat specimen of a film or a paper substrate under specified d0184 conditions. This test method covers the measurement of the wetting tension of astj 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.
These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. 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 compressive stress in a spring-loaded testing apparatus. The minimum thickness required for Procedures B and D is a function of that required to asrm removal of the adtm as a free film.
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. Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.
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 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.
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. It is intended to determine whether the working life conforms to the minimum specified working life of an adhesive required by consistency tests or by bond strength tests, or by both.
This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment asttm. It is 1d084 from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part.

This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. 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 is applicable to both gun and knife grades.
Test periods depend upon the reasonable life expected from the material in service. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.
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. Additional instruments that can perform the procedure in this test method may also provide equivalent results.
These test methods apply to general plant production equipment and procedures. Since the characteristics that render a material resistant to creep under the condition of test are not yet completely known, the details of the procedure considered herein are those known to have important influences.
Where test liquids other than reagent water are used, the actual liquid used is reported. This test method describes a procedure to aastm slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus. This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.
This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. This test method covers the measurement of Krebs Unit KU s1084 to evaluate the 1d084 of paints and related coatings using the Stormer-type viscometer. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. 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.
The uncertainties of extrapolation should be considered in deciding upon the length of the test. There is no similar or equivalent ISO standard.
For such adhesives, tack may be measured as the force required to separate adhesive and adherend at the interface shortly after they have been brought into contact under a defined load of axtm duration at a specified temperature. Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. 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.

This practice covers two procedures applicable to all adhesives having a relatively short working life. Procedures A and C are not recommended for films less than 0. Two types of apparatus for measuring the contact angle using the procedure in this test method are described.
Two methods are described as follows:. It covers the measurement of both the asgm angle of contact and the angle of contact after a defined elapsed period of time may be measured. These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume resistivity, surface resistance, and surface resistivity of electrical insulating materials, or the corresponding conductances and conductivities.
