ASTM International’s cannabis committee ( D37 ) is developing a proposed standard that will provide recommendations for laboratories involved in the industry. According to members, the standard (WK63913) will outline best lab practices, recommended certifications, various types of analyses, and the quality assurance functions for labs working with cannabis. Cary Black, consultant for Orion GMP,…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Robert Morgan, tel +1.610.832.9732; rmorgan@astm.org Release #10581

ASTM International’s recently formed committee on cannabis ( D37 ) has approved its first two standards. Both deal with the aspects of moisture in cannabis. According to committee members, cannabis is generally sold by weight, with a large measure of its quality determined by the amount of moisture it contains. The standards provide a procedure to determine the water activity in a cannabis sample…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Robert Morgan, tel +1.610.832.9732; rmorgan@astm.org Release #10556

A new ASTM International test method could play an important role in supporting next-generation nuclear power through advanced ceramics, which are used to make many parts of nuclear reactors. According to ASTM International member Michael Jenkins, the new standard harmonizes many test methods developed over the years to measure the stress-strain behavior and strength of composite tubes subjected…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, James Farrell, tel +1.610.832.9661; jfarrell@astm.org Release #10482

A proposed ASTM International standard will help guide the development of detergents that clean medical devices, helping support patient safety and health. The practice for characterizing detergents for the cleaning of medical devices ( WK58652 ) is being created by the organization’s committee on soaps and other detergents ( D12 ). “Currently, there are no consensus methods for characterizing…

Today, the U.S. Department of Agriculture selected the Safety Equipment Institute - a subsidiary of ASTM International - to manage the certification program that supports labeling thousands of products as "biobased." The renewal of this five-year contract will mean that more and more people will be able to find and purchase products that are made and packaged using renewable materials. “This…, Program Contact:, Pat Gleason, tel. +1.703.442.5732; pgleason@seinet.org, Media Inquiries:, Dan Bergels, tel. +1.610.832.9602; dbergels@astm.org Release #10160

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…

Ceramic and glass companies, as well as universities and government laboratories, will be the primary users of a new ASTM standard that allows for the flexural strength determination of components made in a round shape or after finish machining with minimal waste. The standard, ASTM C1684 , Test Method for Flexural Strength of Advanced Ceramics at Ambient Temperature-Cylindrical Rod Strength, was…
