In Germany flame arresters are tested in accordance with the TRbE standard (Technical Rules for Inflammable Liquids) and approved by the German Eederal Physical-Technical Institute (PTB) and the German Eed-eral Institute for Material Research and Testing (BAM). However, this standard will be superseded by the new CEN standard. 

Some reference material producers/suppliers use different names to describe their materials. For example, a Standard Reference Material (SRM) is a certified reference material issued by the National Institute of Standards and Technology (NIST), while European Reference Materials (ERMs) are CRMs produced under a joint collaboration between three European reference materials producers, i.e. BAM (Federal Institute for Materials Research and Testing, Germany), IRMM (European Commission, Joint Research Centre, Institute for Reference Materials and Measurements, Belgium) and LGC (UK).

Phase 2. In the seeond phase of the study, the partieipants were asked to analyze three extraeted and cleaned sediment samples using the DR CALUX bioassay. Sediments used for extraetion and cleanup were freshwater sediments from the Western Seheldt, The Netherlands. The sediment extracts were prepared by the Royal Institute for Fishery Research (RIVODLO), IJmuiden, The Netherlands, aeeording to the protoeol given here. Dilutions of the supplied sediment extracts were prepared by the partieipants in DMSO and tested for dioxin and/or dioxinlike content. On each 96-well mierotiter plate, a 2,3,7,8-TCDD standard ealibration curve was analyzed. Raw data as well as eonverted data were used for statistieal evaluation.

In the case of the porosity measurements, in addition to the same cellulose samples, samples of oak and white pine were also examined. These samples of wood were ordinary commercial lumber samples (the same pine having been previously used in fire experiments at the Center for Fire Research of the National Institute for Standards and Technology). The pine had an initial dry density of 0.377 g/cc, and the oak 0.734 g/cc. Both of these wood samples were pyrolyzed for two hours at 1273 K, in helium, in order to prepare the chars for testing. The char yields were in the neighborhood of 28% by mass of the starting oak and 26% by mass of the starting pine. 

Marinos Pitsikalis received his B.Sc. and Ph.D. from the University of Athens, Greece in 1989 and 1994, respectively. His postdoctoral research was done at the University of Alabama at Birmingham, with Prof. J. W. Mays (1995-1996). Since 1998, he has been a Lecturer at the Industrial Chemistry Laboratory, Department of Chemistry, University of Athens. He has been a Visiting Scientist at the University of Milano, Italy (March 1991) University of Alabama at Birmingham (September-October 1993) Max Plank Institute for Polymer Science, Germany (August 1994) National Institute for Standards and Technology (December 1995) and IBM Almaden Research Center (February 1995). He has published 35 papers in refereed scientific journals and made 30 announcements at international scientific conferences. 

A standard preparation of thyrocalcitonin, prepared to the salt-fractionation stage by Method 2 above, is available from the Medical Research Council, Department of Biological Standards, National Institute for Medical Research, Mill Hill, London, and is distributed in ampules containing 0.25 MRC unit. When 0.01 MRC unit is injected intravenously into a 150-g rat, it produces a fall of approximately 10% in the plasma calcium after 50 minutes, i.e., this new unit is approximately 100 times larger than that described by Hirsch et al. (H4) and 1000 times larger than that of Baghdiantz et al. (Bl). From the in-... 

Some 35 years ago, the Macaulay Institute for Soil Research in Aberdeen was approached by the NIST, then the National Bureau of Standards, as to the feasibility of preparing a reference soil certified for its extractable content as distinct from its total content. At the time, the difficulties of preparation, stability and analysis were considered too great. The collaborative approach...

Chemical standards are used to test response in military field units, and the National Institute for Standards and Technology (NIST) has recently become active in establishing procedures to calibrate explosive detectors. Research teams have proposed substances that conld provide a reference to calculate values. Will these or any others be incorporated into IMS instruments or methods WiU the role of ion residence time in drift tnbes or analyzers be widely recognized as a factor in the appearance of mobility spectra How will we know that we have the same ion species For the next-generation instruments as suggested, will the identity of the ion species be controlled and known sufficiently so mobility may be considered an intrinsic parameter of an gas ion Until then, the method is disproportionately limited by control of experimental variables.

Nano-composites are the subject of intense research for a number of properties such as improved barriers to gas, higher mechanical strength, and improved flame retardancy. Plate-like particles of special clays, one nanometre (one billionth of a metre) thick by 1000 nanometres in diameter, are being studied as FRs in plastics by the US National Institute for Standards and Technology (NIST), Gaithersburg, Maryland. Initial research showed that the addition of as little as 5% of nano-sized clay particles could produce a 63% reduction in the...
