||Rubber Standards Are Bouncing Off the Walls
Numerous rubber testing standards are being developed by ASTM
Committee D11 on Rubber. Michael Kent Warner, an instrument specialist with
CCSi, Inc., Akron, Ohio, and chair of several D11 task groups,
described these developments:
D 395, Standard Test Methods for Rubber PropertyCompression Set Revisions
that include changes to the description of the fixtures contact
surfaces were drafted by Subcommittee D11.10 on Physical Testing.
D 531, Standard Test Method for Rubber PropertyPusey and Jones IndentationA
complete editorial and organizational update on ballot was drafted
Sept. 00 by Subcommittee D11.10 on Physical Testing.
D 2228, Standard Test Method for Rubber PropertyAbrasion Resistance
(Pico Abrader)A revision being balloted under the jurisdiction
of Subcommittee D11.15 on Degradation Tests will include the reformulation
of calibration compounds and cutting knife specifications, as
well as the reorganization of sections on procedures and calibration.
D 3767, Standard Practice for RubberMeasurement of DimensionsProposed
changes by Subcommittee D11.10 are being balloted that will incorporate
an expanded mass/force table for 10 ± 2 kPa.
Draft Standard Test Method for Rubber PropertyResilience by
Impactwill offer a single comprehensive rebound test method by incorporating a revision of ASTM
D 1054, Standard Test Method for Rubber Property-Resilience Using a
Rebound Pendulum, ASTM D 2632, Standard Test Method for Rubber Property-Resilience by Vertical
Rebound, Deutsches Institut für Normung 53512, Prüfung von Kautschuk
und Elastomeren - Bestimmung der Rückprall-Elastizität (Schob-Pendel),
and International Organization for Standardization 4662, Rubber
Determination of Rebound Resilience of Vulcanizates. Currently
being balloted, the ASTM test method was proposed Oct. 00 by
Task Group D11.14.04 of Subcommittee D11.14 on Time and Temperature
Dependent Physical Properties, chaired by Warner.
Draft Standard Test Method for Rubber Properties-Measurement of
Cure and After-Cure Dynamic Properties Using a Rotorless Shear
Rheometeris being balloted by the Society. It was developed by
a task group of Subcommittee D11.14 on Time and Temperature-Dependent
Physical Properties, chaired by John Dick.
