Interesting fact was observed with dynamic modulus of elasticity test method
. During experiment was obtained higher reduction of dynamic modulus (Fig.
In 1997, the National Institute of Environmental Health Sciences (NIEHS) established the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM), an ad hoc federal interagency committee to address the growing need for obtaining regulatory acceptance of new toxicological test methods
. The thought was that simultaneous agency evaluation of new methods that addressed the 3Rs (reduction, refinement, and replacement) of animal testing by an interagency group could greatly speed up and harmonize the cross-agency acceptance and adoption of new methods into federal toxicity testing guidelines.
The proposed standard, ASTM WK38233, Test Method
for Dirt Pick-Up Resistance for the Films of Architectural Paints and Stains, is currently being developed by Subcommittee D01.42 on Architectural Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
Environmental test methods
. Combined cold, dry heat or temperature change with bump or random vibration
According to Edward Tobolski, chairman of committees responsible for both test methods
, in the past, hardness testers normally were designed to perform either micro (E384) or macro (E92) hardness tests.
Wilson's primality test method
states that n is a prime number if and only if (n-1)!
The test method
can be used to determine the quality of PE butt fusion joints made in the field or in qualification testing.
Therefore, the test method
prescribes accelerated aging in the laboratory to measure the change in thermal resistance, which is attributable to changes in cell gas composition caused by diffusion of air into and blowing agent out of the foam cells.
IT9.17 describes the precise steps to be taken in using each of the three accepted test methods
for measuring the residual thiosulfate level in silver halide film products.
If a potential material supplier provides confusing specifications, ask questions and get clarification, If evaluating materials using a specific test method
, reference that test method
correctly in program documentation.
In 1993 the Technical Advisory Group reported to Congress that a safety test method
had been devised.
The new test method
, which includes new testing equipment, was recently approved by the American Association of State Highway and Transportation Officials (AASHTO) as test number TP60-00, "Standard Test Method
for the Coefficient of Thermal Expansion of Hydraulic Cement Concrete." It is included in the 2000 edition of the AASHTO Provisional Standards.
