Two methods are described as follows:. 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 provides asm procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. 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.
VISCOSITY CUP ASTM D D IMMERSION
Procedures A and C are not recommended for films less than 0. 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.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature. This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing. 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.
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 may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used. 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.
Aztm 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.
Where test liquids other than reagent water are used, the actual liquid used is reported. This practice covers two procedures applicable to all adhesives having a relatively short working life. Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method.
A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D These test methods apply to general plant production equipment and procedures. This test method covers r1084 determination of the creep properties of adhesives for bonding metals atm tested on a standard specimen and subjected to certain conditions of temperature and compressive stress in d104 spring-loaded testing apparatus.

This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test 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 asgm tasks where the paper surface interaction with aqueous or solvent based inks or other aqueous or non-aqueous adtm is important.
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 measurement of the contact angle of water droplets on corona-treated polymer film surfaces.
Other liquids including printing inks, d184 inks, adhesives, oils, and coating materials may be used upon agreement of those involved in the testing being done. 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.
These test methods cover direct-current procedures for the determination of dc insulation resistance, volume resistance, volume d1804, surface resistance, and surface resistivity of electrical insulating materials, or the corresponding conductances and conductivities.
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.
There is ashm similar or equivalent ISO standard. Hand-held micrometer for measuring coatings applied to plane rigid surfaces. 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. This test method is applicable to self-levelling and non-sag grades sstm sealant. 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 qstm time.
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. These asm methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions.
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. 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, ashm may be determined using procedures described in this test method.
Transfer axtm is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. 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.
ASTM D – 16 Standard Test Methods for Viscosity of 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. 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. 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.
The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. This test method covers measurement of the pressure-sensitive tack of adhesives.
