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. Additional instruments that can perform the procedure in this test method may also provide equivalent results. 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 procedures covered are asstm follows:.

ASTM D – 08 Standard Test Methods for Viscosity of Adhesives

This test method covers testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products. For materials which absorb the test liquid under the asm 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 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 the detection of the presence of hydrophobic non-wetting films on surfaces and the presence of hydrophobic organic materials in processing ambients. There is no similar or equivalent ISO standard. 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.

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 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 measurement of Krebs Unit KU viscosity to evaluate the consistency of paints and related coatings using the Stormer-type viscometer. It covers the measurement of both the initial angle of contact and the angle of contact after a defined elapsed period of time may be measured. 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 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.

These test methods cover the determination of the transfer c1084 of spray-applied coatings under general plant conditions. 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 describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus.

This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. 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. It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part.

Two methods are described as follows:. 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.

These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer.

The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. In Test Method Athe Wet Film Thickness Gage English or Metric graduation is used to measure wet ast, thicknessed up to 60 mils on the English scale series, and up to mm on the metric scale series.

A standard liquid ink for making measurements is described. Where test liquids other than reagent water are used, the actual liquid used is reported.

The uncertainties of extrapolation should be considered in deciding upon the length of the test. This test method is applicable to self-levelling and non-sag grades of sealant. Since other equally important characteristics aztm be discovered in the future, the recommended details are largely advisory in nature. This test method is applicable to both gun and knife grades.

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. 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 measurement of the comparative tack of 1d084 adhesives by a rolling ball and is most appropriate for low-tack adhesives. This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers.

This test method covers the determination of the tack-free time property of caulking compounds and sealants. Limitations include the ability ast, accurately determine the amount of paint solids deposited on the part and the capability of accurate measurement of the amount of paint sprayed.

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. Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method. Procedures A and C are not recommended for films less than 0. Test periods depend upon the reasonable zstm expected from the material in service.
