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. 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.
Since other equally important characteristics may be discovered in the future, the recommended details are largely advisory in nature.
Test periods depend upon the reasonable life expected from the material in service. The uncertainties of extrapolation should be considered in deciding upon the length of the test. 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 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. This test method is applicable to self-levelling and non-sag grades of sealant.
Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by 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.
This test method measures the angle of contact when a drop of liquid is applied to the surface of a specimen of paper. 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. A standard liquid ink for making measurements is described.
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. Two types of apparatus for measuring the contact angle using the procedure in this test method are described. Additional instruments that can perform the procedure in this test method may also provide equivalent results. A different procedure using an automated instrument for measuring angle of contact can be found in ASTM D This test method covers the determination of the quantity of adhesive solids applied in a spreading or coating operation.
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 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 test method covers the measurement of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. Procedures A and C are not recommended for films less than 0. 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 procedures covered are as follows:. Hand-held micrometer for measuring coatings applied to plane rigid surfaces. These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer.
Two methods awtm described as follows:. In Test Method Athe Wet Film Thickness Gage English or Axtm 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 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.
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 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 is not applicable to coatings that will be readily aetm under the load of the measuring instruments, as the instrument probe must be placed directly on the coating surface to take a f1084. This test method covers determination of the temperature at which a specified needle penetration occurs when specimens e1084 subjected to specified controlled test conditions. 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 is applicable to both gun and knife grades. This test method covers the measurement of the wetting tension of a polyethylene or polypropylene film surface in aztm with drops of specific test ast in the presence of air.
This test method covers measurement of the pressure-sensitive tack of adhesives. 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 d0184, without leaving a residue visible to the eye.
For such adhesives, tack may be measured as the force required to separate adhesive and adherend ast, 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 measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball and is most appropriate for low-tack adhesives.
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 testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions. 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 calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. 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.
These test methods apply to general plant production equipment and ashm. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions. 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 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.
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 r1084 equipment used. 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 satm be determined using procedures described in this test method.
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.
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.
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.
Where test liquids other than reagent water are used, the actual liquid used is reported. This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces. There is no similar or equivalent ISO standard.
