ASTM D4535-21 - Standard Test Methods for Measurement of Thermal Expansion of Rock Using Dilatometer
June 1, 2021 - ASTM International

1.1 These test methods cover the laboratory measurement of the one-dimensional linear thermal expansion of rocks using a dilatometer. 1.2 The methods are applicable between temperatures of 25°C to 300°C. Both bench top and confined measurement techniques are...

ASTM D4607-14(2021) - Standard Test Method for Determination of Iodine Number of Activated Carbon
June 1, 2021 - ASTM International

1.1Â This test method covers the determination of the relative activation level of unused or reactivated carbons by adsorption of iodine from aqueous solution. The amount of iodine absorbed (in milligrams) by 1 g of carbon using test conditions...

ASTM D5064-16a(2021) - Standard Practice for Conducting a Patch Test to Assess Coating Compatibility
June 1, 2021 - ASTM International

5.1 In performing maintenance of a coating system, the new coating being applied must be compatible with the existing coating. While general guides exist which indicate compatibility of different generic types of coatings, differences in manufacturer’s formulation and...

ASTM D5159-21 - Standard Guide for Dusting Attrition of Granular Activated Carbon
June 1, 2021 - ASTM International

4.1 Three forces can mechanically degrade a granular activated carbon: impact, crushing, and attrition. Of these three, attrition, or abrasion, is the most common cause of dust formation in actual service. Published test procedures to determine the “hardness†of...

ASTM D5178-21 - Standard Test Method for Mar Resistance of Organic Coatings
June 1, 2021 - ASTM International

1.1Â This test method covers the determination of the mar resistance on smooth, flat surfaces. Results are expressed in terms of force-to-mar films of organic coatings such as paint, varnish, and lacquer when applied to smooth, flat planar panel surfaces. 1.2Â...

ASTM D5321/D5321M-21 - Standard Test Method for Determining the Shear Strength of Soil-Geosynthetic and Geosynthetic-Geosynthetic Interfaces by Direct Shear
June 1, 2021 - ASTM International

5.1Â The procedure described in this test method for determination of the shear resistance of the soil and geosynthetic or geosynthetic and geosynthetic interface is intended as a performance test to provide the user with a set of design values for the test...

ASTM D5327-97(2021)e1 - Standard Practice for Evaluating and Comparing Transfer Efficiency of Spray Applied Coatings Under General Laboratory Conditions
June 1, 2021 - ASTM International

1.1Â This practice covers the evaluation and comparison of the transfer efficiency of spray-applied coatings under general laboratory conditions. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process,...

ASTM D5462-21 - Standard Test Method for On-Line Measurement of Low-Level Dissolved Oxygen in Water
June 1, 2021 - ASTM International

5.1Â DO may be either a corrosive or passivating agent in boiler/steam cycles and is therefore controlled to specific concentrations that are low relative to environmental and wastewater treatment samples. Out-of-specification DO concentrations may cause corrosion in boiler...

ASTM D5631-21 - Standard Practice for Handling, Transportation, and Storage of Halon 1301, Bromotrifluoromethane (CF 3 Br)
June 1, 2021 - ASTM International

4.1Â This practice provides requirements for the handling, transportation, and storage of Halon 1301 encountered in distribution through both commercial and military channels. It is intended to ensure that Halon 1301 is handled, transported, and stored in such a way that...

ASTM D6037-21 - Standard Test Methods for Dry Abrasion Mar Resistance of High Gloss Coatings
June 1, 2021 - ASTM International

5.1Â Coatings, particularly the high gloss coatings used on automobiles, boats, toys, etc., are subject to a wide variety of conditions (for example, wiping, cleaning, and exposure) that can mar their surface. The ability of these coatings to maintain their appearance is an...
