ISO schedules new PM standards

The International Standards Organisation (ISO) Technical Committee 119 covers all aspects of Powder Metallurgy with its secretariat based at SIS in Stockholm, Sweden. The Chairman of ISO TC 119 is Dr Jan Tengzelius of Höganäs AB, Sweden. The secretariat recently issued its second newsletter (May 2012) which outlined new or updated PM standards being prepared, and included details of the next plenary meeting of TC119 which will be held in Tokyo October 11-12 to coincide with the 2012 PM World Congress in Yokohama.

The newsletter reported that a final draft (FDIS) for the new updated standard ISO 5755: ‘ Sintered metal materials – Specifications’, has been sent out for voting and the new standard will be ready for publishing by end of 2012. The standard includes about 150 different materials including low-and high-alloyed steels as well as copper-based materials. The included materials are presented at three different density levels and typically also with different contents of carbon. Chairman of the working group for this Standard is Dr Brian James.

Dr James is also responsible for the group developing the first ISO standard for MIM materials and the final draft of ISO/FDIS 22068: 6’ Sintered metal injection moulded materials – Specifications’ has been sent out for voting by the members. The standard includes about 50 different materials including low-alloyed steels, stainless steels, soft magnetic materials and titanium. The density is defined as less than 5% of residual porosity. The MIM standard is expected to be ready for publishing by the end of this year.

The newsletter further reported that two new ISO standards have been published for: ‘Determination of cleanliness of PM parts’ (ISO 28279:2011), and ‘Abrasion test for Hard Metals’ (ISO 28080:2011). Also a new working group has been established by a group of Swedish companies to establish a national Swedish standard for ‘Hot Isostatic Pressing’. The first focus of the group will be to agree on a test method and equipment for preparing samples and testing for argon content in the HIPed material.
