Health Sciences Descriptors

"The concepts that characterize the DeCS vocabulary are organized in a tree structure allowing a search on broader or narrower terms or on all terms from the same tree within the hierarchical structure. DeCS is a dynamic vocabulary totaling 30,895 descriptors, of which 26,664 come from MeSH, and 4658 are exclusively DeCS. There is an addition of 2051 hierarchic codes from DeCS categories in 1491 MeSH descriptors. The following are the DeCS categories and their total number of descriptors: Health Surveillance (828); Homeopathy (1,944), Public Health (3,491); and Science and Health (219).

Australian Standard Classification of Drugs of Concern

"The Australian Standard Classification of Drugs of Concern (ASCDC) is the Australian statistical standard for classifying data relating to drugs which are considered to be of concern in Australian society. The ASCDC is essentially a classification of type of drug of concern based on the chemical structure, mechanism of action and effect on physiological activity of the drugs of concern. The classification of Type of Drug is described as the 'main classification structure' throughout the ASCDC document.

Classification of Eye Movement Abnormalities and Strabismus

"The design and conceptual foundation of the CEMAS classification scheme follows traditional ideas and attempts to remain clinically pragmatic. The scheme describes three broad categories of abnormalities: 1) Horizontal Deviations, 2) Vertical Deviations and Special Forms of Strabismus, and finally, 3) Nystagmus and Other Ocular Oscillations and is comprised of eight major areas."

Classification of Pesticides by Hazard

"This document sets out a classification system to distinguish between the more and the less hazardous forms of selected pesticides based on acute risk to human health (that is the risk of single or multiple exposures over a relatively short period of time). It takes into consideration the toxicity of the technical active substance and also describes methods for the classification of formulations.

Globally Harmonized System of Classification and Labelling of Chemicals

"The goal of the GHS is to identify the intrinsic hazards found in substances and mixtures and to convey hazard information about these hazards. The criteria for hazard classification are harmonized. Hazard statements, symbols and signal words have been standardized and harmonized and now form an integrated hazard communication system. The GHS will allow the hazard communication elements of the existing systems to converge. Competent authorities will decide how to apply the various elements of the GHS based on the needs of the competent authority and the target audience."

Classification of Forest Products

"This classification is designed to cover the wood and wood-based products for which FAO and ECE collect statistics on a regular basis. Included is wood taken from forests or from trees outside the forest, bark and cork; charcoal; wood and wood-based materials resulting from the first processing of the wood available from forest operations (including sawnwood, railway sleepers, veneer sheets, wood pulp and wood residues); and materials resulting from further processing of some of these materials (e.g. wood-base panels, paper and paperboard); waste paper and recoverable wood products.
