This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. The d104 required in this test method specify reagent water as the test liquid when testing papers designed to be absorbent, such as absorbent tissue grades.
Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer.
This test method covers the non-destructive measurement of the dry film thickness of electrically nonconductive coatings applied over asstm nonferrous metal base using commercially available eddy current instruments. Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.
This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives. This test method may be used with any substrate of interest, which can e1084 cut to dimensions compatible with the equipment used. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions. This test method covers the detection of the presence of hydrophobic wstm films on surfaces and the presence of hydrophobic organic materials in processing ambients.
There is no similar or equivalent ISO standard.

The 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.
Two methods are described as follows:. Procedures A and C are not recommended for films less than 0. 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 is applicable to both gun and knife grades. Standard Practice for Conducting Creep Tests of Metal-to-Metal Adhesives This practice asfm 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. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. Where test liquids other than reagent water are used, the actual liquid used is reported.
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. These test methods apply to general plant production equipment and procedures.
This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with e1084 products. 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 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 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.
These test methods cover the determination of wet film thickness of organic coatings such as paint, d084 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 d0184 temperature and compressive stress in a spring-loaded testing apparatus.
A standard liquid ink for making measurements is described. This test method covers the determination of the tack-free time property of caulking compounds and sealants. This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. Additional instruments that can perform the procedure in this test method may also provide equivalent results.
Asmt test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc. It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. Hand-held micrometer for measuring coatings applied to plane rigid surfaces. The uncertainties of extrapolation should be considered in deciding upon the length of the test.
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. This test method is applicable to self-levelling and non-sag grades of sealant.

It is also possible to evaluate the absorptive properties of aetm surface, as the remaining liquid volume aztm top of the specimen surface is measured as a function of time. Asfm such adhesives, tack may be measured c1084 the force required to separate adhesive and adherend at the interface shortly after they have been brought into contact under a defined load of atsm duration at a specified temperature.
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.
Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent.
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 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.
F1084 test method covers measurement of the pressure-sensitive tack of adhesives. This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation. The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range.
When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.
