Classification levels

The United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) includes an internationally standardized guidance procedure on Transformation/Dissolution Protocol (T/DP) for metals and sparingly soluble metal compounds (United Nations, 2007), recently validated by the OECD (Organization for Economic Cooperation and Development). To establish the acute aquatic hazard classification level of a metal-bearing substance under the GHS, data from the T/DP are compared with an acute ecotoxicity reference value (ERV) derived under conditions similar to those of the T/DP. 

These aspects are very important, clearly illustrated by the fact that the U.S. Food and Drug Administration (FDA) has three classification levels for medical products ... 

Case 3 Dredged material of the two highest classification levels (toxicity classes V and VI) must not be relocated in inland waterways according to HABAB-WSV (2000) and should not be relocated in coastal areas according to HABAK-WSV (1999). 

Work lines (type of activities) were selected as the upper classification level. The following (below) classification level comprises the objects of complex decommissioning and environmental rehabilitation, such as NS, NPSS, MV, CMB and RC units. 

And, finally, the last classification level includes the lists of specific measures related to the objects and tasks and aimed at task solving. 

A justification and brief description of these approaches at each classification level, as well as interim and final results of the performed analysis, are given below. 

P5. At the next classification level the fuzzy classes and 2 of the partition P have to be split. We may compute a binary fuzzy partition of Ai, i = 1,2, as usual using GFNM algorithm. To obtain a stronger correla-... 

The therapeutic area is defused as being the third ATC (Anatomical Therapeutic Chemical Code) classification level. 

Preparedness for commercial nuclear power plants includes a system for notifying the public if a problem occurs at a plant. The emergency classification level of the problem is defined by these four categories ...

The First Review Conference took cognisance of the fact that 85% of the information submitted to the Secretariat had been classified as confidential by the originating States Parties. The First Review Conference requested the Council, assisted by the Secretariat, to study the situation in relation to the classification of information held by the OPCW. The First Review Conference encouraged the Secretariat and the States Parties to review their respective practices in assigning levels of classification to such information, and if possible, and in accordance with the State Party s confidentiality procedures, to reduce the classification level they assign to such information, in order to increase work efficiency and ensure the smooth functioning of the system to protect confidentiality. 

Other useful parameters for the classification of savanna types in the Llanos are the degree of inundation (e.g. non-seasonal, seasonal or hyperseasonal Sarmiento, 1984) and the nutrient status of the soil (e.g. eutrophic or oligotrophic Schargel, 2(X)3). Because both refer to environmental conditions and not to the savanna vegetation proper, we suggest they should be employed as complementary characters of each savanna type or for upper hierarchical classification levels. 

Laser Classification (old system). There are four classes of lasers for safety purposes, with Class 1 lasers being the least hazardous and Class 4 lasers being the most hazardous. Proper laser classification is very important because it provides the basis for laser safety design. The required safety features for a given laser are based on its classification. The laser safety community has developed this laser classification system based on injury potential. The classification levels are dependent upon the lasers wavelength, power or energy, exposure duration, pulse repetition frequency (PRF), and the size of the laser beam. 

These laser classification levels in the old system are shown in Table 2.13. 

The DIN VDE 801 specification provides eight (8) levels of safety classification, there is however some correlation between pairs of classification levels in the DIN VDE 801 specification and the lEC 65A WGIO document.
