ISO/TS 19337, “Nanotechnologies – Characteristics of working suspensions of nano-objects for in vitro assays to evaluate inherent nano-object toxicity,” has just been released. The new technical specification is available now from Document Center Inc. It is a guide for evaluating possible impacts of “nano-objects” on human health and the environment.
As we become more familiar with the properties and effects of nano materials, we discover that tests for understanding biological effects for them may differ from traditional materials. After all, many biological tests involve dissolving a chemical in water. When you do this with many nano-objects, they tend to undergo changes like dissolution into their ionic counterparts or absorbed into the culture medium itself. Without these properties being understood and accounted for, tests may not give you accurate results.
So the ISO/TS 19337 was developed to describe the essential characteristics and measurement methods of working suspensions containing nano-object samples for in vitro toxicity assays. It is intended to be used to develop reliable test results for nano-objects to be used by regulators, the general public, manufacturers, and end users.
This technical specification has the usual scope, referenced documents, and definitions sections (including abbreviated terms). The bulk of the technical material comes in Section 5, Characteristics and measurement methods, and Section 6, Reporting. The document also provides you with 4 informative annexes – Flow of measurements, measurement and evaluation of stability, measurement of metal ions, and measurement of culture medium components. A 23-item bibliography completes the publication.
