The certification of the nitrogen BET specific surface areas of six materials in the range 0.1 to 8 m2/g CRM 169,170,171,172,173 and 175
This report describes the work done at five laboratories on the certification of six low specific surface area particulate reference materials, RMs 169 to 173 and 175; these include three aluminas with specific surface areas of 0.104, 1.05 and 2.95 m2/g, a natural quartz (2.56 m2/g), a rutile titania (8.23 m2/g) and tungsten (0.181 m2/g). Results for a bronze (0.063 m2/g), which was not certified as a reference material, are also included. Measurements were made by the nitrogen BET method, and details of the methods employed at the five laboratories are given.
