Actions from the meeting in April 2016: 1. Four SAC test methods are in place and were revised: SH/T 0721 (Grease, coefficient of friction and wear), SH/T 0784 (Grease, pass load/O.K. load), SH/T 0847 (Oil, coefficient of friction and wear) and SH/T 0882 released by 11-2014 (Oil, pass load/O.K. load). 2. New test method to evaluate anti-fretting properties of greases based was approved by SAC TC280 and will be released. 3. SAC TC280 accepted the project “Simulation of synchronizer by using SRV”. Draft text to be submitted by 03-2017. Discussions on a parallel ASTM test method. 4. A procedure for “Wear Volume” is under development for SAC TC280.
2015 Tianjin Explosions
(2016)
In 2015 a series of explosions occurred at a container storage station at the Port of Tianjin, China, on Wednesday, 12 August 2015, that killed over one hundred people and injured hundreds of firemen and others. The first two explosions happened within 30 seconds of each other at the facility. The second explosion was larger and involved the detonation of about 800 tons of ammonium nitrate. The cause of the explosions was not known at first, but an investigation of the Chinese authorities concluded in February 2016 that an overheated container of dry nitrocellulose was the cause of the initial explosion. Colleagues of the Nanjing University of Science and Technology and BAM worked together to analyze the reasons and the process of that incident based on knowledge about the properties of the involved substances, particularly ammonium nitrate and nitrocellulose, and potential mechanism of initiation and propagation.

Tribological profile of hydraulic oils by using SRV. The determination of a set of critical, tribological by using different SRV-based test methods. The SRV-based concept of tribological profile generates the wear volumes on two triboelements (specimen), the extreme pressure properties and friction under different contact pressures.
Thus, the benchmark and validation of hydraulic oils bear on a wider range of tribological properties.
The RR2016 extends with six hydraulic oils to other base oil types including biodegradable fluids, which were all tested according to ASTM D7043 in order to consolidate the correlation between SRV and V104C.
The implementation of new 2-D materials based technologies in production processes requires the development of quality management tools. These have to be underpinned by appropriate measurements. Consequently there is a need for the development of the metrology for measurement methods, the development of certified reference materials (CRM) and finally standardization. This chain represents the ideal way to practically useful standards. The presentation will give an overview on the main players in the field and summarize the recent status of activities. At the highest level the metrology of chemical characterization of 2D materials is in the scope of the International Meter Convention, specifically the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology (CCQM). Pre-standardization is an activity field of the Versailles Project on Advanced Materials and Standards (VAMAS). Standardization is mainly addressed by addressed ISO Technical Committees. A summary on available CRMs relevant to the characterization of nano materials has been prepared by BAM. Examples from the work of BAM’s Division 6.1 “Surface Analysis and Interfacial Chemistry” showcasing the characterization of chemically modified graphene surfaces are given and specific needs for the development of metrology are addressed.
In the discussion the audience is invited to define specific needs which will be streamlined to the respective bodies!
Die Präsentation ist der Startschuss für die Wasserstoffkolloquien der BAM. Sie beginnt mit Adolf Martens und zeigt den Weg vom Foresight-Prozess Wasserstoff bis zum Kompetenzzentrum H2Safety@BAM. Es werden die Kompetenzfelder vorgestellt und die handelnden Personen. Dies leitet über zu den drei Vorträgen des Tages und den Vortragenden.
(Pre)Standardisation and Metrology in Microbeam Analysis – Ongoing Activities and Opportunities
(2023)
The presentation addresses the current ongoing projects as well as the gaps and opportunities in microbeam analysis within ISO/TC 202 Microbeam Analysis standardisation body and in-liaison Technical Working Areas (TWAs) at the pre-standardization platform of VAMAS (Versailles Project on Advanced Materials and Standards).
