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 asym of film thickness of dried films of paint, varnish, lacquer, and related products using micrometers. 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.

The procedures covered are as follows:.

ASTM D – 08 Standard Test Methods for Viscosity of Adhesives

The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridef1084 vinylidene chlorideor c1084 materials having a wide Vicat softening range.

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

Transfer efficiency is the ratio of paint solids satm to the total paint solids used during the application process, expressed as a percent. Two methods are described as follows:. In Test Method Athe Wet Film Thickness Gage English or Metric graduation is used to d108 wet film thicknessed up to 60 mils on the English scale series, and up to mm on the metric scale series. 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 covers the determination of the viscosity of Newtonian or near-Newtonian paints, varnishes, lacquers, aetm related liquid materials with the Ford-type efflux viscosity cup.

The test method may be used with any liquid of interest, which is compatible with the equipment used, particularly d184 regard to liquid viscosity, tackiness, and vapour pressure evaporation. This practice covers a means by which the storage satm of an adhesive can be measured using viscosity and adhesive performance testing. This test method covers the non-destructive measurement qstm the dry film thickness of electrically nonconductive coatings applied over a nonferrous metal base using commercially available eddy current instruments.

This practice provides a procedure aatm the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions. The uncertainties of extrapolation should be considered in deciding upon the length of the test.

Procedures A and C are not recommended for films less than 0. 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. 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.

There is no similar or d10844 ISO standard. This test method covers measurement of the contact angle of water droplets on corona-treated polymer film surfaces.

These test methods apply to general plant production equipment and procedures. These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions.

Sealants requiring slight heating to facilitate extrusion from the cartridge or gun are also described by this test method.

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.

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 testing of the components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products.

ASTM D1084 – 16

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.

These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc. It is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part.

These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer.

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. 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. asm
