"This glossary, a revision of the IUPAC "Glossary for Chemists of Terms Used in Toxicology" [Pure Appl. Chem. 65, 2003 (1993)] incorporating new and redefined terms from the "Glossary of Terms Used in Toxicokinetics" [Pure Appl. Chem. 76, 1033 (2004)], contains definitions and explanatory notes, if needed, for terms frequently used in the multidisciplinary field of toxicology. The glossary is compiled primarily for those scientists and others who now find themselves working in toxicology or requiring a knowledge of the subject, especially for hazard and risk assessment. Many medical terms are included because of their frequent occurrence in the toxicological literature. There are three annexes, one containing a list of abbreviations and acronyms used in toxicology, one containing a list of abbreviations and acronyms used by international bodies and by legislation relevant to toxicology and chemical safety, and one describing the classification of carcinogenicity according to the weight of evidence available."

"At its first set of meetings, in September 1976, the recently constituted IUPAC Commission 111.2 (Physical Organic Chemistry) initiated a project on the definition of terms used in Physical Organic Chemistry. It was noted that the formulation of novel scientific concepts was often arbitrary and unclear, and that scientific communication between physical organic chemists had been hampered by disagreement on the meaning of important terms. It was agreed that the progress of the subject could be helped by the compilation of a Glossary of terms with the co-operation of active research workers, authors, and teachers of the subject. The provisional version of the Glossary was published in 1979, and a historical account of procedure and progress up to that stage was outlined in the provisional publication, IUPAC PHYSICAL ORGANIC GLOSSARY (1979)."
"Soft soldering is the process of joining metal parts by heating and running a low-melting point alloy between the two surfaces being joined. As cooling takes place, the alloy solidifies and results in a secure joint. For most purposes, the low- melting point solder alloy is a composition of lead and tin. Solder melts at a temperature less than 3000C, which is far below the melting temperature of the metal being joined and produces a low strength joint. Soft soldering is used extensively in ..."
