Research and development purposes

As a consequence of the optimization of performance, different performing instruments were first designed for one specific task. However, the best instruments from the latest generation correspond to universal instruments that make it possible to run several types of experiments such as fluorimetry, luminometry, and densitometry for instance. This has interesting consequences for users who work in different domains of luminescence for research and development purposes and do not have to buy a whole range of instruments. 

Placing biocidal products on the market for research and development purposes will be permitted without authorisation. However, depending on the nature of the trial and the likely risk, information may have to be notified to or pre-assessed by the Competent Authority. 

The availabihty of microcarriers has not only opened up industrial opportunities but also allowed the laboratory worker to produce substantial quantities of cells and cell products for research and development purposes. 

The ultimate test of catalyst performance is the vehicle test described in Section 1.2. In such a vehicle test all the reaction conditions that influence the conversion reached over the catalyst vary simultaneously in a interdependent fashion, as they are fixed by the speed and the load of the vehicle at each moment of the test. For research and development purposes, however, it is useful to evaluate the catalyst performance using fewer parameters or parameters that can be varied independently. Several simplified test procedures have therefore been developed. 

Data requirements for new chemicals are tied to the quantity of chemical actually placed on the market. The Base Set consists of chemistry, production details, proposed uses and handling precautions, acute toxicity, skin and eye irritation, in vitro mutagenicity, and environmental fate [3]. Base Set data are required for chemicals sold in quantities of <1 tonne a chemicals used in small quantities, for research and development purposes only, may be excused. Further tests are added to the base set requirements as the quantity sold increases up to the highest level of 1000 tonnes a /manufacturer, or 5000 tonnes total. 

A substance that is not on the TSCA Inventory and is manufactured, imported, processed, or distributed for export only may be used for research and development purposes without filing a PMN, provided that the requirements for that exemption from the PMN requirements are met." " ... 

Instead of filing an MCAN, a person who intends to make or import a new intergeneric microorganism for research and development purposes, but... 

The Court in Dow Chemical Co. v. PA, 605 E2d 673 (3rd Cir. 1979) found that the processing, import, or manufacture of small quantities of chemicals for research and development purposes was a commercial purpose and was therefore within the scope of 8 of TSCA the 8(e) Comment Document, 34, Usts the citations for EPAs assertions that research and development materials are subject to TSCA 8(e) reporting. 

This material is not listed on the TSCA Inventory. It should be used for research and development purposes only under the direct supervision of a technically qualified individual. 

For the research and development purposes where the emphasis is on new compounds not yet contained in the libraries, similarity search systems able to... 

At the same time, NIOSH recognizes that the same novel characteristics of engineered nanoscale materials that make them attractive for research and development purposes may also mean that their fundamental toxicity characteristics differ from their bulk counterparts. Thus, commercialization must be balanced against preventing reasonably foreseeable injuries which might accompany any exposure to engineered nanoscale materials in the workplace. 

Thus if the substance in question is being used for research and development purposes, it does not meet the test of being used for a pesticidal purpose and would not need registration prior to initiating the research and development work. 

Supported Liquid Membranes. A SLM can be fabricated in at least three different geometries. Planar or flat sheet SLMs are very useful for laboratory research and development purposes, but the surface area to volume ratio of flat sheets is too low for industrial applications. Spiral wound and hollow fiber geometries can... 

There is a great need, for specification and research and development purposes, to be able to assess material performance quickly. The main feature of instrumented impact testers is the ability to follow the entire history of contact... 

Brittleness temperature has very little practical value since the data obtained by such a method can only be used in applications in which the conditions of deformation are similar to those specified in the test. The method is, however, useful for specification, quality control, and research and development purpose. 

Until recently, the rheological measurements were confined to test labs for quality control, research, and development purposes. New techniques for on-line rheological measurements have been developed, bringing the analytical instrumentation to the production floor. This is accomplished by employing a closed-loop instrument which diverts a portion of the process stream to a measurement head and then returns it to the process. Within the measurement head, most of the material flows through a bypass channel and a fraction of the stream is pumped across a capillary die, using precision gear pumps. A similar concept, employed by another manufacturer, utilizes a slit die to measure viscosity. An open-loop on-line rheometer, which does not return the diverted melt stream to the process after measurement, splits the diverted melt stream to two capillary dies of different LID ratios...
