ASTM International, which defines over 12,000 processing standards and operates globally, has released a new standard which the organisation says will help to prevent the contamination of biopharmaceuticals with foreign particles during the single use system (SUS) manufacturing process. The ASTM committee on manufacture of pharmaceutical and biopharmaceutical products (E55) developed the standard, which the organisation says will soon be published as E3230. According to ASTM International member Klaus Wormuth, over the last 10 years, single-use bioprocessing equipment has become more widely used in biopharmaceutical manufacturing, providing significant flexibility. Wormuth notes that SUS also provides both economic and sustainability benefits compared to conventional stainless-steel equipment. “Since SUS equipment is not cleaned prior to use, the single-use manufacturer needs to take great care and produce the SUS equipment in a clean room environment to minimise particle levels,” said
