ASTM D – 16 Standard Test Methods for Viscosity of Adhesives
Hand-held micrometer for measuring coatings applied to plane rigid surfaces. Where test liquids other than reagent water are used, the actual liquid used is reported. These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc.
This test method is applicable to self-levelling and non-sag grades of sealant. A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D 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.
When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants. 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 wstm appropriate for low-tack adhesives.
Two types of apparatus for measuring the contact angle using the procedure in this test method are described.
ASTM D1084 – 16
These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions. Two methods are described as follows:. There is no similar or equivalent ISO standard. Test periods depend upon the reasonable life expected from the material in service. 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.
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 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 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 enable removal of the sample as a free film.
This test astk covers the determination of the tack-free time property of caulking compounds and sealants. This test d10844 measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. This test method covers x1084 determination of the quantity of adhesive solids applied in a spreading or coating operation. This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers.
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. 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.
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 apply to general plant production equipment and procedures. 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.
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.
Seta Zahn Cup No. 3
This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus. 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.
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 test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions.
The procedures covered are as follows:. atm
The test method provides a visual evaluation to relate troweled d0184 profile and trowel pickup. This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. 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 is not applicable to coatings that asmt 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. The uncertainties of extrapolation should be considered in deciding upon the length of the test. This test method covers measurement of the pressure-sensitive tack 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.
This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products.
VISCOSITY CUP ASTM D D IMMERSION
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. It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. This test method is applicable to both gun and knife grades.
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 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.
