Organization of tests

The complexity of the system, due to the large number of devices controlling the various operating modes and their geographical distribution around the 27 kilometer ring reqnired the establishment of a validation strategy capable of detecting all the hardware and software errors in a short period of time.

The OECD Principles of GLP provide quality assurance concepts concerning the organization of test laboratories and the conditions under which laboratory studies are planned, performed, monitored, and reported. The purpose of the GLP Principles is to make certain that test data are reliable. Like the Test Guidelines, the Principles of GLP began to be developed at the end of the 1970s and were established in the 1981 Council Decision on MAD. 

A complete and generic benchmark should go beyond a simple set of test cases. It should offer a systematic organization of tests that is consistent, complete, and minimal. Consistent means that the existence of every test case should be justified by some specific feature upon which the tool or technique is evaluated through the test case. Complete means that for every important feature of the mapping tool under evaluation there is a test case. Minimal means that there are no redundant test cases, i.e., more than one test case for the same feature. 

The main purposes of the System of accreditation is to ensure reproducibility of measurements, harmonisation of rules and procedures of the National system of accreditation with guidelines of international organizations and national systems of different countries, creation of conditions for mutual recognition of the results of testing, calibration, attestation. 

Metrological attestation of the procedure of testing is realized by the developing organization with the aid of experts - specialists in NDT. Metrological attestation of the procedure of testing is performed after accumulation of statistical data. 

Several countries have developed their own standard test methods for cellular plastics, and the International Organization for Standards (ISO) Technical Committee on Plastics TC-61 has been developing international standards. Information concerning the test methods for any particular country or the ISO procedures can be obtained in the United States from the American National Standards Institute. The most complete set of test procedures for cellular plastics, and the most used of any in the world, is that developed by the ASTM these procedures are pubUshed in new editions each year (128). There have been several reviews of ASTM methods and others pertinent to cellular plastics (32,59,129—131). 

Vegetable and seed oils as well as some synthetic base stocks present a new class of biodegradable base stocks. These fluids (10) have excellent biodegradation properties as measured by criteria developed by the Environmental Protection Agency (EPA) or Organization of Economic Cooperation and Development (OECD). OECD 301 and EPA 560/6-82-003 measure the biodegradation of lubricants. These tests were developed to measure the degradation of oil, especially two-cycle ok, on waterways. Aquatic toxicity criteria toward fish is also found to be acceptable for this class of fluids as measured by EPA 560/6-82-002 and OECD 203 1-12. 

In a battery of tests, which determine the tendency of chemicals to inhibit aquatic organisms, accumulate in such organisms, and degrade in the environment, 2-hydroxy-2-nitro-l,3-propanediol was found to have low potential for harm in the environment (7).

Further it is planned to use tests - organisms of various trophie levels to eaiTy out systematie reseai ehes on eompaiison of results of an estimation of quality of natural waters to the help of the different generalized pai ameters. 

Environmental analytical association Ecoanalytica produce standai d samples during last 12 years. Two topics will be discussed. The first is the principles of development of staictures and maintenance of quality of standai d samples. The organization of manufacture and maintenance of their stability ai e considered too in the report. Besides them authors consider scientifically-methodical aspects of preparation of samples for experimental check of technical competence of analytical laboratories and also samples for interlaboratory tests. 

In general, wherever I felt the organization of the material could be improved, I did it. The most notable of this are the changes to the testing chapter to aid in clarity.
