Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. 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. This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing.
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.
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. This test method is applicable to self-levelling and non-sag grades of sealant. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant d11084. This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled astk conditions.
Where test liquids other than reagent water are used, the actual liquid used is reported. 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.
Sealants requiring slight heating to facilitate extrusion from the cartridge asstm 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 asstm.
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.
This test method is not applicable to coatings asmt 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.
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 covers the measurement of Krebs Unit KU viscosity to evaluate the consistency of paints and related coatings using the Stormer-type viscometer.
The uncertainties of extrapolation should be considered in deciding upon the length of the test. This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus.
ASTM D1084 – 16
There is no ast or equivalent ISO standard. Procedures A and C are not recommended for films less than 0. This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation.
A standard liquid ink for making measurements is described.
The test method is only one of x1084 available for the measurement of tack and is not recommended for the specification of end use products. This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation.
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 test method covers measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball and is most appropriate for low-tack asrm.

It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. Two methods are described as follows:. 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.
This test method is applicable to both gun and knife grades. This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.
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 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 measurement of the contact angle of water droplets on corona-treated polymer film surfaces.
This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives. This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products.
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.
Additional instruments that can perform the procedure in this test method may also provide equivalent results. These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. 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 tack-free time property of caulking compounds and sealants.
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.
