The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. 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. When properly conducted, the test will enable detection of molecular layers of hydrophobic organic contaminants. 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.

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.

Where test liquids other than reagent water are used, the actual liquid used is reported. This test method covers measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball and is d1048 appropriate for low-tack 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 the measurement of film thickness of dried films of paint, varnish, lacquer, and related atm using micrometers. 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.

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. Other liquids including printing inks, writing inks, adhesives, oils, and ast materials may be used upon agreement of those involved in the asgm being done.

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 practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation.

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.

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.

Hand-held micrometer for measuring coatings applied to plane rigid surfaces. This test method covers the measurement of Krebs Unit KU viscosity to evaluate the consistency of paints and related coatings using astk Stormer-type viscometer. This test method may be used with any substrate of interest, which can be cut to dimensions compatible with the equipment used.

On very rough or porous surfaces, the sensitivity of the test may be significantly decreased. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions.

These test methods apply to general plant production equipment and procedures.

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 minimum asrm required for Procedures B and D is a function of that required to enable removal of the sample as a free film. Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.

ASTM D – 16 – Standard Test Methods for Viscosity of Adhesives

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 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.

Test periods depend upon the reasonable life expected from the material in service.

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. 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 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.

The test method is applicable to those adhesives which form a bond of measurable strength rapidly upon contact with another surface and which can ast, removed from that surface cleanly, that is, without leaving a residue visible to the eye. Procedures A and C are not recommended for films less than 0.

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.

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.

  ASTM C876 PDF

This test method covers determination of the temperature at which a specified needle penetration occurs when specimens are subjected to specified controlled test conditions. 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 covers the measurement of the apparent viscosity of shear-rate-dependent adhesives. Two types of apparatus for measuring the contact angle using the procedure in this test method are described. 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.

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 is applicable to self-levelling and non-sag grades of sealant.

The procedures covered are as follows:. This test method is applicable to both gun and knife grades. Additional instruments that can perform the procedure in this test method may also provide equivalent results.

These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent.

This practice covers a means by which the storage life of an adhesive can be measured using viscosity and adhesive performance testing. This practice covers two procedures applicable to all adhesives having a relatively short working life. This test method covers measurement of the pressure-sensitive tack of adhesives. The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range.

This test method covers measurement of the contact angle of water droplets on corona-treated xstm film surfaces. 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.
