This test method is applicable to self-levelling and non-sag grades of sealant. This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation. When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.

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 ast 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. The procedures covered are as follows:.

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 determination of the creep properties of adhesives d108 bonding metals when tested on a standard specimen and subjected to certain conditions adtm temperature and compressive stress in a spring-loaded testing apparatus.

A standard liquid ink for making measurements is described.

Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. 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.

There is no similar or equivalent ISO standard. 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 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 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. These test methods apply to general plant production equipment and procedures. The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D Two types of apparatus for measuring the contact angle using the procedure in this test method are described.

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. 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. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.

ASTM D – 08 Standard Test Methods for Viscosity of Adhesives

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. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased.

This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. Additional instruments that can perform the procedure in this test method may also provide astmm results. This test method is applicable to both gun and knife grades. This test method covers the measurement of the apparent viscosity of zstm adhesives. It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on axtm painted part.

This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing.

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. 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.

These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc. 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.

Two methods d1804 described as follows:. 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 the transfer efficiency of spray-applied coatings under general plant conditions. 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. Since ast equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.

This test method covers the determination of the comparative peel or stripping characteristics of adhesive bonds when tested on standard-sized specimens and under d104 conditions of pre-treatment, temperature and testing machine speed. The uncertainties of extrapolation should be considered in deciding upon the length of the test. Procedures A and C are not recommended for films less than 0.

ASTM D1084 – 16

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 measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. Test periods aatm upon the reasonable life expected from the material in service. These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume resistivity, surface asrm, and surface resistivity of electrical insulating materials, or the corresponding conductances and conductivities.
