The author thanks Drs. S. Komatsu, H. Kanda, K. Kimoto, T. Aizawa, R. Souda, and S. Matsumoto of Advanced Materials Laboratory/National Institute for Materials Science (AML/NIMS) for their cooperation in experiments and the fruitful discussion of the results. 

While interest in amorphous alloys was becoming vane over the time, the paradigm shift in materials science brought about by the discovery of amorphous metals and rapid solidification cannot be underestimated. The interest of physicists, chemists, materials scientists, and engineers became refocused from well-ordered crystalline materials to disordered and nanocrystalline phases. Shortly, substantial R D programs were initiated in the USA, Japan, and worldwide both at universities and national government laboratories. Foundations have been established for the advance of the science of nanomaterials. 

Initial investment for the Idaho National Engineering Laboratory (INEL) Cols Test Pit demonstration was 2.3 million (1996 dollars). An estimated cost of 1250 (1996 dollars) per cubic yard of frozen material extracted is expected for large-scale, high-efficiency application of the technology (D15324C, p. 5). 

Standard reference material (SRM) for wavelength accuracy, stray light, resolution check, and photometric accuracy can be purchased from NIST. Certified reference materials (CRMs) which are traceable to NIST and recertification services can be purchased from instrument manufacturers and commercial vendors [12]. The cost of neutral-density filters and prefabricated standard solutions in sealed cuvettes can be substantial. When purchasing performance verification standards from a secondary supplier other than a national standard organizations such as NIST in the United States and National Physical Laboratory (NPL) in the United Kingdom, make sure that the traceability of the standards are available in the certificates. The traceability establishes the relationship of individual results to the national standard through an unbroken chain of comparisons. 

Inaccurate laboratory measurements can mean wrong medical diagnosis and treatment, lost production time, wasted energy and materials, manufacturing rejects, and product liability. The U.S. National Institute of Standards and Technology and national standards laboratories around the world distribute Standard Reference Materials, such as metals, chemicals, rubber, plastics, engineering materials, radioactive substances, and environmental and clinical standards that can be used to test the accuracy of analytical procedures.1... 

Work in fluorine chemistry at the University of Texas at Austin, and previously as the Massachusetts Institute of Technology, has had as its principal sponsor the Air Force Office of Scientific Research, after initial support from the U.S. Air Force Materials Laboratory. We are grateful for other support from the National Science Foundation and the Office of Naval Research. Work in fluorine chemistry at Rice University has been supported over more than a decade by the U.S. Army Research Office, Durham, by the U.S. Atomic Energy Commission, by the National Science Foundation, by the U.S. Air Force Materials Laboratory, and the Robert A. Welsh Foundation.

The calibration laboratory is connected to the national standards level via comparison measurements on laboratory samples taken from the calibration laboratory, which are analysed by the national standards laboratory (PTB or DGKC) and the calibration laboratory to be accredited or re-evaluated. Agreement within predefined limits is required as a proof of the competence of the calibration laboratory. The sample with the known value (the national laboratory s value) is then used by the calibration laboratory as measurement standard for its work. It is the advantage of this kind of transferring standards over the transfer of reference materials from the shelf that these standards perfectly match the matrices occurring in the calibration laboratory. 

This example is of a traceability [1] protocol [2] for the chemical measurement of an element by a primary method of measurement [3]. It can be used for the certification of a single-element reference material by a national reference laboratory. This protocol relates to a very pure strontium nitrate solution, stabilized by 10% (by volume) nitric acid1. This solution is to be certified for the amount of strontium substance n(Sr) per unit mass of aqueous solution m (sol). The general measurement method described is based in part on the experience of certifying a currently available certified reference material (CRM) [4], Standard Reference Material (SRM) 3153a [5],...

The 30g mixture burning test has been adopted by the United Nations 4 01 based on oxidizing burning rate tests(the 5 pound test) 3 used in America. Uehara 41 and Hasegawa 4 21 have concluded that this method should be adopted for the Fire Services Law in Japan. The experimental data supporting their conclusion are archived at the Hazardes Material Laboratory of Japan Carlit Co., Ltd.
