• OECD Guidelines for the Testing of Chemicals, Section 1 : Physical-Chemical properties - http://dx.doi.org/10.1787/20745753 -- OECD Guidelines for the Testing of Chemicals, Section 1 : Physical-Chemical properties - The OECD <i>Guidelines for the Testing of Chemicals</i> is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. They are a set of tools for professionals, used primarily in regulatory safety testing and subsequent chemical and chemical product notification, chemical registration and in chemical evaluation. They can also be used for the selection and ranking of candidate chemicals during the development of new chemicals and products and in toxicology research. This group of tests covers physical-chemical properties -- Book.
• This Test Guideline (TG) describes a harmonised procedure to determine the Volume Specific Surface Area (VSSA) of powdered solid manufactured nanomaterials (MNs). The VSSA (in m2/cm3) of a material is calculated by multiplying its mass specific surface area (in m2/g) with its skeletal density (in g/cm3). The determination of the external and internal (mass) specific surface area (SSA) of powdered solid MNs is done by the Brunauer, Emmett and Teller (BET) method. This TG also provides instructions on how to determine the skeletal density (ρ) of the MN by gas pycnometry.
