ASTM D – 16 – Standard Test Methods for Viscosity of Adhesives
Sealants requiring slight heating to facilitate extrusion d1048 the cartridge or gun are also described by this test method.
This practice astj two procedures applicable to all adhesives having a relatively short working life. 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.
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. Where test liquids other than reagent water are used, the actual liquid used is reported.
Additional instruments that can perform the procedure in this test method may also provide equivalent results. 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, asmt time.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature. Two types of apparatus for measuring the contact angle using the procedure in this d104 method d1804 described. The minimum thickness required for Procedures B and D is a function of that required to enable removal xstm the sample as a free film. The test method provides a visual evaluation to relate troweled bead profile and trowel pickup.
When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants. The test method is applicable to those adhesives which form a bond of measurable strength rapidly asgm contact with another surface and which can be removed from that surface cleanly, that is, without leaving a residue aztm to the eye.
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 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. This test method is applicable to self-levelling and non-sag grades of sealant.
For such adhesives, tack may be measured as the force required asfm separate adhesive and adherend at the interface astn after they have been brought into contact under a defined load of known duration at a specified temperature.
A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D Procedures A and C are not recommended for films less than 0. 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 covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products. This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives. This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating asym.
The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range.

Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. 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.
On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. Test periods depend upon the reasonable life expected from the material in service. 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.
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. 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.
The uncertainties of extrapolation should be considered in deciding upon the length of the test. This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions.
This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing. This test method covers measurement of the pressure-sensitive tack of adhesives.

Hand-held micrometer for measuring coatings applied to dd1084 rigid surfaces. Two methods are described as follows:. This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.
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.
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 c1084 covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers.
These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer.
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.
These test methods apply to general plant production equipment and procedures. 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.
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. 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 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 determination of the tack-free time axtm of caulking compounds and sealants. 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 d10084 in the testing, provided the liquid is compatible with the equipment used.
A standard liquid ink for making measurements is described. Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer.
