This study examined two questionable aspects of using truss plates together with finger-joined wood truss members, namely the possible strength reductions in either the truss plate joint or the member. The lumber was kiln-dried No. 2 grade spruce–pine–fir. The finger joints were "horizontal" and glued with a phenol resorcinol adhesive. Project A dealt with the strength of truss plate joints; in this project, truss plate joints were tested in tension on both faces of 38 × 64 mm lumber and on the 89 mm face of 38 × 89 mm lumber, and both parallel and perpendicular to grain loading. Project B examined the effect of truss plates on the tensile and flexural strengths of finger-joined lumber. Specimens waisted to 38 × 38 mm containing truss plates pressed into both faces of the finger joints were tested in tension parallel to grain, whereas specimens of 38 × 89 mm also containing plates in both faces were tested in bending about both weak and strong axes.The statistical analysis indicated no reduction in strength for the ten-replication tests in both projects A and B. However, the test results suggest that there is a possible inherent weakness associated with the plug-shear failures in project A and the failures at the last row of the plate teeth in project B. The implications of these results on the design of truss plate joints have been adopted by the CSA Technical Committee on Engineering Design in Wood.

Abstract IUPAC, AOAC, and ISO participate in developing, validating, and adopting analytical methods for international use. Harmonization of the different interests of these organizations is desirable, as is harmonization of parameters of precision of test methods. ISO Technical Committee 69 is responsible for standards that deal with statistical interpretation of test results and data, sampling procedures, and precision of test methods.

The offshore pilot test of Exxon’s Submerged Production System (SPS) has reached a successful conclusion. This pilot test encompassed the entire spectrum of SPS equipment, spanning from the well completion intervals to, but not including, common surface processing and storage facilities. Since the SPS is designed to meet all the life cycle needs of a subsea field, one of the objectives of the pilot test was to evaluate both the techniques and the equipment used to install, operate, and maintain a prototype version of the SPS. The equipment under test was designed for use in water depths up to 2000 ft, but with minor modifications it is capable of operating in significantly greater depths. Evaluation of pilot test results has shown that the deep water installation techniques are practicable and that the deep water maintenance machinery is competent to repair any failures likely to occur in an operating system. One of the most significant problems in conducting the pilot test was achieving adequate quality control during equipment manufacture. The test results have demonstrated that, with relatively minor modifications, the SPS is suitable for commercial application.

Available Information

Polybutenes are the isotactic polymers of isobutene and n-butene. Polybutenes provide viscosity or emulsifiability to more than 80 cosmetic products in concentrations up to 50%. The results of acute oral and percutaneous toxicity tests of Polybutenes show these materials to be relatively harmless. Acute skin irritation tests on rabbits showed no or mild irritation. Other test results indicate that Polybutenes are not toxic: (a) there were no observable effects in rats after inhalation at concentrations up to 18.5 mg/l of air; (b) there was only mild, transient eye irritation in rabbits; (c) intravaginal application of concentrated Polybutene daily for 30 days produced no observable effect in rabbits. Chronic oral toxicity in rats fed up to 20,000 ppm for three successive generations showed no impairment in reproduction. The available human clinical data indicated only very mild effects. Skin tests for sensitization, irritancy, phototoxicity, and photosensitization were limited to cosmetic formulations. On the basis of the available information, it was concluded that Polybutenes are safe as presently used in cosmetics.

PPG-9, -25, and -40 Diethyhnonium Chloride are quaternary ammonium salts that function as antistatic agents in cosmetic formulations. Only PPG-9 and -25 Diethylmonium Chloride are reported to be used. Neither animal test data nor clinical test results were available. No data were provided in response to requests of interested parties to supply the needed data. Accordingly, the available data are insufficient to support the safety of these ingredients in cosmetics. The additional data needed include: (1) current concentration of use; (2) dermal absorption using PPG-9 Diethylmonium Chloride; if significantly absorbed, then a 28-day dermal toxicity study will be needed; (3) two genotoxicity assays, at least one in a mammalian system, of PPG-9 Diethyhnonium Chloride; if positive, then a 2-year dermal carcinogenicity study using NTP methods may be needed; (4) human skin sensitization and irritation at concentration of use; and (5) impurities data, especially nitrosamines. Depending on the findings in these studies, additional data such as reproductive and developmental toxicity may be needed.

Laboratory Results

Abstract The International Consortium for Harmonization of Clinical Laboratory Results (ICHCLR) was established to fulfill recommendations identified by an international conference convened to review the available infrastructure and challenges in achieving harmonization of results among different measurement procedures. The specific objectives of the ICHCLR are to: prioritize measurands by medical importance, coordinate the work of different organizations, and stimulate development of technical and regulatory processes to achieve harmonization. Central to these objectives is the website “www.harmonization.net” developed by the ICHCLR as an information portal designed to provide a resource center for global activities to harmonize and standardize results from clinical laboratory measurement procedures. Priorities based on medical impact are provided for measurands for which harmonization is needed or work to implement harmonization is incomplete or inactive. By making information available regarding harmonization activities in progress or planned, coordination of work to harmonize laboratory measurement procedures will minimize duplication of effort and optimize the use of limited resources. A toolbox of technical procedures developed by ICHCLR to be considered when developing a process to achieve harmonization for a measurand is presented. The ICHCLR initiated a proposal to ISO Technical Committee 212 for a harmonization protocol as the basis for calibration traceability when there are no other higher order reference system components available. The ICHCLR offers a unique service to prioritize measurands in need of harmonization and to provide a centralized approach to organize global efforts to achieve harmonization of clinical laboratory test results.
