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.
The test method provides a visual evaluation to relate troweled bead profile and trowel pickup. Two methods are described as follows:.
This test method describes a procedure to measure slump, or sag, resistance of a trowel-grade carpet adhesive using a button slump test apparatus. 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 practice covers two procedures applicable to all dd1084 having a relatively short working life. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. On very rough or porous surfaces, the sensitivity of the test may be significantly decreased.
These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish and lacquer.

This test method measures the angle of contact when astn drop of liquid is applied to the surface of a specimen of paper. Procedures A and C are not recommended for films less than 0. This test method covers measurement of the pressure-sensitive tack of adhesives.
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.
There is no similar or equivalent Asgm standard. This test method covers the measurement of the apparent viscosity of shear-rate-dependent adhesives. 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 aztm. This test method is applicable to self-levelling and non-sag grades of sealant.
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 quantity of adhesive solids applied in a spreading or coating operation. This test method covers a procedure for the determination of the tack-free time property of single- and multi-component elastomeric sealants commonly d1804 for sealing, caulkingand glazing in buildings and related construction.
It is intended to determine whether the working life conforms aatm 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.
The test method is not recommended for ethyl cellulose, nonrigid poly vinyl chloridepoly vinylidene chlorideor other materials having a wide Vicat softening range. Additional instruments that can perform the procedure in this test method may also provide equivalent results. 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.
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 tensile stress in a spring-loaded testing apparatus.

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 the transfer efficiency of spray-applied coatings under general plant conditions.
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. The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions.
This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation. 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 procedures.
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. Two types of apparatus for measuring the contact angle using the procedure in this test method are described. This test method covers testing of sstm components of mechanical pump dispensers spray or flow types for compatibility with consumer-type products.
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. The procedures covered are as follows:. 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.
This test method may be used with any substrate of interest, which can be cut to dimensions compatible with xstm equipment used.
