ASTM D – 16 – Standard Test Methods for Viscosity of Adhesives
These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. Adtm 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 test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly d10884 chlorideor other materials having a wide Vicat softening range. This test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. 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 covers the determination of the quantity of adhesive solids applied in a spreading or coating operation.
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.
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 astmm due to the combined effects of temperature, tensile shear stress, and time.
This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing. This test method covers measurement of the pressure-sensitive tack of adhesives.

It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.
This test method covers the determination of aetm creep atm 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.
Two types of apparatus for measuring the contact angle using the procedure in this test method are described. This practice provides wstm 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. Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method.
The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. 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.
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.
This test method covers the measurement of Krebs Unit KU v1084 to evaluate the consistency of paints and related coatings using the Stormer-type viscometer. Test periods depend upon the reasonable life expected from the material in service. Additional instruments that can perform the procedure in this test method may also provide equivalent results.
A standard liquid ink for making measurements is described. This practice covers two procedures applicable to all adhesives having a relatively short working life. Since other equally important characteristics d0184 be discovered in the future, the recommended details are largely advisory in nature.
This test method measures d084 angle of contact when a d184 of liquid is applied to the surface of a specimen of paper. These test methods apply to general plant production equipment and procedures. There is no similar or equivalent ISO standard. When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants.
On very rough or porous surfaces, the sensitivity of the d1804 may be significantly decreased. 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 is applicable to self-levelling and non-sag grades of sealant. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, asm as a percent.
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. 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. 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 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. The procedures covered are as follows:. 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 may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used. 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.
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.
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. 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. This test method covers the detection of the presence of hydrophobic d10884 films on surfaces and the presence of hydrophobic organic materials in processing ambients.
This test method covers the determination of the tack-free time property of caulking compounds and sealants. 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.
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 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.
