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. 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 measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. This test method covers measurement of the pressure-sensitive tack of adhesives. Procedures A and C are not recommended for films less than 0. 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.
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.
The procedures covered are as follows:. This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc.

Test periods depend upon the reasonable life expected from the material in service. 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 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 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.
On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. 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. A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D The test method provides a visual evaluation to relate troweled bead profile and trowel pickup.
There is no similar or equivalent ISO standard. Measurements are applicable to spindle, disk, T-bar and coaxial cylinder viscometer. This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers.
Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. It is intended to determine whether the working life conforms to the minimum asgm working life of an adhesive required by consistency tests or by bond strength tests, or by both. This practice covers two procedures applicable to all adhesives having a relatively short working life.
ASTM D – 16 Standard Test Methods for Viscosity of Adhesives
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 upon contact with another surface and which can astk removed from that surface cleanly, that is, without leaving a residue visible to the eye. The test method may be used with any liquid of interest, which is compatible with the equipment 1d084, particularly with regard to liquid viscosity, tackiness, and vapour pressure evaporation.
Since the characteristics that render a material resistant to creep under the condition of test are not yet completely known, d10084 details of the procedure considered herein are those known to have important influences.
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 covers the determination of the quantity of d10884 solids applied in a spreading or coating operation.
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 used.
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 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 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 measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball and is most appropriate for low-tack adhesives.
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. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.
Two types of apparatus for measuring the contact angle using the procedure in this test method are described.
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.
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.
The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range.
ASTM D1084 – 16
These test methods apply to general plant production equipment sstm procedures. This test method covers the determination of the tack-free time d108 of caulking compounds and sealants. This test method is applicable to both gun and knife grades. 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.
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 testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products.
This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used. Where test liquids other than reagent water are used, the actual liquid used is reported. This test method covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, asstm related liquid materials with the Ford-type efflux viscosity cup.
