Further analysis of the size effect in indentation hardness
tests of some metals, Journal of Materials Research 10(11): 2908-2915.
The most demonstrative properties to observe the effect of fillers are tensile strength, indentation hardness
, flexural strength, and flexural modulus.
Our paper examined the entire gamut of Flexidone performance specifications, from solubilising temperatures for various alkyl chain lengths to indentation hardness
at low temperatures to cold flexibility thresholds.
Results of the Brinell indentation hardness
test are shown in Table 5.
This brochure contains durometers and durometer systems that cover the entire spectrum of indentation hardness
testing of rubber-like materials.
Volume three of the 15-volume series documents practices and test methods for measuring crack growth behavior and fatigue in metals, the effect of temperature and stress relaxation, elastic properties, indentation hardness
, residual stress, grain size, and specimen preparation.
First, the specimen thickness and indentation hardness
of the conditioned foam after a recovery time are measured.
In the measurement of hardness one differentiates between methods to determine scratching hardness, drilling hardness and cutting hardness, and the semiquantitative method of determining indentation hardness
The output of these hardness testers is typically a single indentation hardness
value that is a measure of the relative penetration depth of the indentation tip into the sample.
The ball indentation hardness
of the same TPU parts was measured conforming to DIN 53 456 with a HPK4/22 device by Kogel.
North America follows American Society for Testing and Materials (ASTM) standards, which are very close to ISO standards, says Samuel Low, chairman of the ASTM subcommittee on indentation hardness
testing and a member of the National Institute for Standards and Technology (NIST) technical staff.
Mar and scratch resistance appears to be independent of Tukon and other indentation hardness
results, which is a little surprising.
