... This article summarizes the body of available standards for sampling of chemical and biological agents on workplace surfaces, including skin. These standards consist of voluntary consensus standards such as those promulgated by ASTM International, the International Organization...

... considerations but also for performance evaluation. The Public Health and Industry Advisory Committee recommended the use of ASTM test procedures. The certification program was first started in 1959 and led to the creation of National Sanitation Foundation Standard Number 14 for Thermoplastic Materials in 1965...

... Despite technological advances of the 21 st century, mortars and stuccos for masonry restoration projects continue to be specified using portland cement. Without standards or codes specifically designed for historic buildings, owners and contractors often unknowingly incorporate incompatible...

... This preliminary material with regard to draft standard for Air Quality on Commercial Aircraft is presented here in hopes that it will aid in defining research needs for the future. Aircraft are different from buildings. Commercial aircraft fly through an environment that is hostile to human...

... to the importance of the underlying flashing systems. Many diverse industry organizations have attempted to set standards for installation practices as related to their own area of practice; i.e., the NRCA and SMACNA; however, there is no single source that ties these disparate standards together and binds them...

... The acoustic emission (AE) method, though rather difficult in application and interpretation of results, has a great potential for characterization of stress, bearing properties, fatigue, and fracture of materials. The existing NDT standards that employ AE cover only a limited number...

... The reasons for the importance of terminological standardization in computerized information systems are discussed as well as the special aspects pertinent to materials databases. Current terminological activities in the materials field are reviewed and progress and difficulties noted. In order...

... Development of energy standards in the early 1970's was initiated and accelerated by the “energy crisis”. Criteria were proposed based on “professional judgement” and accepted when “consensus” was reached. That process performed a valued service but the conditions have since changed. Today...

... At the Swedish National Testing Institute (SP) window thermal transmittance ( U -value) measurements are carried out in a Guarded Hot Box (GHB). It is shown that the GHB meets the requirements of the relevant Swedish Standard (SS 024212,13) and International Standard Draft Proposal (ISO/DP 8990...

... In reactor metrology, the neutron spectrum of the spontaneous fission of Cf-252 has been used as a standard for many years. Nevertheless, the shape of this spectrum has not yet been unambiguously established. Only recently, the situation changed completely. Based on experimental data...

... The Laboratoires des Ponts et Chaussées (LPC) of France are about to publish six new standards on oedometric testing. Two of these tests (controlled gradient test and controlled rate of strain test) are similar to those used in other countries. The other four have been under development...

...-wireline and the seabed deployment systems and their principal subsystems. Major emphasis is placed on two topics: (1) quality assurance of in-situ testing and (2) a discussion of test descriptions and test standardizations, particularly with respect to the field vane and cone penetrometer. Some...

... a data base is presented of pressuremeter, cone penetrometer, standard penetration and undrained shear strength tests results. Correlation equations between the various parameters are given and the large scatter is shown. In a third part the magnitude of the pressuremeter modulus is discussed in light...

... Calibration values of secondary conductivity standards obtained on a periodic basis, both for the Boeing Company and for commercial customers, have shown various drift patterns. Presently, a 100-kHz bridge used with an H-P 9825 computer compares unknown secondary standards against carefully...

... This paper discusses radioactivity standards in the form of naturally occurring solid materials for use in the assay of solid environmental samples for radioactivity. Topics include the selection and preparation of materials for these standards, “spiking” with radionuclides (if desired), induced...

... We have developed equipment to determine the “thermal conductivity” of insulating materials, in the temperature range 25° to 1600°C, by the hot-wire method. We have based our method on the German draft standard DIN 51046 and on the work of Padgett and Davis at the British Ceramic Research...
