V1084 requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method. 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.

Test periods depend upon the reasonable life expected from the material in service. 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. Additional instruments that can perform the procedure in this test method may also provide equivalent results. 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 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. A standard liquid ink for making measurements is described. 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.
F1084 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 covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.
ASTM D – 16 Standard Test Methods for Viscosity of Adhesives
Two types of apparatus for measuring the contact angle using the procedure in v1084 test method are described. 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.
The procedures covered are as follows:. Procedures A and C are not recommended for films less than 0. This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.
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. Atm test method is applicable to 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. 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.
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 asym are those known to have important influences. The uncertainties of extrapolation should be considered in deciding upon the length of the test. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. This test method is applicable to both gun and knife grades.
This test method covers measurement of the pressure-sensitive tack of adhesives. This test method covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, d184, and c1084 liquid materials with the Ford-type efflux viscosity cup.
This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions. 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 practice covers two procedures applicable to all adhesives having a relatively short working life. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions.
These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air d10844 regulations such as VOC, HAPS, etc.

This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used. 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.
These test methods apply to general plant production equipment and procedures. These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. 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.
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.
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.
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.
Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed d10844 a percent.
Two methods are described as follows:. This test method covers the determination of the tack-free time property of caulking compounds and sealants. 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. This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing.
Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. 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. 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 test aztm covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus.
Where test liquids other than reagent water are used, the actual liquid used is adtm.
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.
