Hand-held micrometer for measuring coatings applied to plane rigid surfaces. These test methods apply to general plant production equipment and procedures.
The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.
These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume resistivity, surface resistance, and surface resistivity of ashm insulating materials, or the corresponding conductances and conductivities. This test method is not applicable to coatings that will be readily deformable under the load of the measuring instruments, as the instrument probe awtm be placed directly on the coating surface to take a reading.
This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives.
ASTM D – 08 Standard Test Methods for Viscosity of Adhesives
It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part.
It covers the measurement of both the initial angle of contact and the angle of contact dd1084 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.
The uncertainties of extrapolation should be considered in deciding upon the length of the test. 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 cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. 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. This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers.
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 practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. 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.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature. This test method measures the contact angle of a test liquid in contact with a flat specimen of a film or a paper substrate aatm specified 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.
Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method. 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.
The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range. This test method covers measurement of the pressure-sensitive tack of adhesives. 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 known duration at a specified temperature.
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. 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.
In Test Method Athe Wet Film Thickness Gage English or Metric graduation is used to measure wet film thicknessed up to 60 mils on the English scale series, and up to mm on the metric scale series.
A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D A standard liquid ink for making measurements is d10084.
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 covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions.
When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.
This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products. In 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.
These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions. Where test liquids other than reagent water are used, the actual liquid used is reported. 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. This test method covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, and related liquid materials with the Ford-type efflux viscosity cup.
This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. 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.
This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used. 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 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.
This test method is applicable to self-levelling and non-sag grades of sealant.
