1.1 This specification covers the material requirements for high-purity, dense aluminum oxide for load-bearing surgical implant applications.
1.2 This specification does not cover finished parts (for example, femoral heads, acetabular inserts, dental implants and the like). It is intended as a qualification of the material as delivered to the parts manufacturer.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
A new ASTM Standard Test Method supports the simple, convenient, and accurate viscosity measurement method employed in portable MiniVisc 3000 Series viscometers from Spectro Scientific. Spectro is one of the world’s largest suppliers of oil, fuel, and processed water analysis instrumentation and software.ASTM D8092 “Standard Test Method for Field Determination of Kinematic Viscosity Using a Microchannel Viscometer” applies to the Spectro Scienitific MiniVisc 3000 (formerly SpectroVisc Q3000)...
ASTM Committee D20 on Plastics and CEN TC411 issued a call for presentation abstracts for the Workshop on Degradable, Biodegradable, and Biobased Products Standards. The 2017 workshop is designed to facilitate a discussion on standards development and implementation regarding testing and specification of biobased, degradable, and biodegradable materials.
Topics for presentation and panel discussions include:
Biobased/renewable resource content testing, specification, and certification;
Aerobic degradability/bi...

Laboratories will soon be able to use a new ASTM International standard to test and better understand biodegradability of plastics in marine environments. The new standard (soon to be published as D7991, Test Method for Determining Aerobic Biodegradation of Plastics Buried in Sandy Marine Sediment Under Controlled Laboratory Conditions) provides ways to simulate how plastics degrade in seawater-soaked sand.
According to ASTM member Francesco Degli Innocenti, the recent discovery of major contamination in the...
In the world of construction materials, ASTM International standards are as much a part of doing business as chemical admixtures are a part of concrete. It takes a combination of sound scientific protocol and industry-leading chemical technologies to develop and implement chemical admixtures and cement additives for the construction industry.
Whether concrete or hydraulic cement, ASTM standard specifications and test methods are always at the forefront of the process, from the evaluation of raw materials to the...
