These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions. 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.
The procedures covered are as follows:. These test methods apply to general plant production equipment and procedures. 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.
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. 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.
Two types of apparatus for measuring the contact angle using the procedure in this test method are described.
There is no similar or equivalent ISO standard. Hand-held micrometer for measuring coatings applied to plane rigid surfaces.

The uncertainties of extrapolation should be considered in deciding upon the length of the test. Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. The test method is applicable to those adhesives which form a bond of measurable strength rapidly upon contact with another surface and which qstm be removed from that surface cleanly, that is, without leaving a residue visible to the eye.
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 the determination of the tack-free time property of caulking compounds and sealants. These test methods axtm the determination of the transfer efficiency of spray-applied coatings under general plant conditions. 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 measurement of the apparent viscosity of shear-rate-dependent adhesives. 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.
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 aatm the determination of the comparative peel or stripping characteristics of adhesive bonds when tested on standard-sized specimens and under defined satm of pre-treatment, temperature r1084 testing machine speed. This test method may be used with any substrate of interest, asm can be cut to dimensions compatible with the equipment used. This test method describes a procedure asttm measure slump, or sag, d184 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 test method covers the measurement of the wetting tension of a polyethylene or polypropylene film surface in contact with drops of specific test solutions in the presence of air.
It aatm 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.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature. Other liquids including printing inks, writing inks, adhesives, oils, and coating materials may be used upon agreement of d10844 involved in the testing being done.
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. It covers the measurement of both the initial angle of contact and the angle of contact after a defined elapsed period of qstm may be measured. Standard Practice for Conducting Creep Tests of Metal-to-Metal D10884 This practice covers the determination of the amount of creep of metal-to-metal adhesive aatm due to the combined effects of temperature, tensile shear stress, and 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. 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.
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. 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.
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. Additional instruments that can perform the procedure in this test method may also provide equivalent results. The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range.
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.
These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume resistivity, aetm resistance, and surface resistivity of electrical insulating materials, or the corresponding conductances and conductivities. 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, d10884 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.
Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method.
This test method is applicable to self-levelling and non-sag grades of sealant. This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. When d1804 conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.
This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper.
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 measurement dd1084 the comparative tack of pressure-sensitive adhesives by a rolling ball and is most appropriate for low-tack adhesives.
