The American Chemical Society (ACS) Committee on Analytical Reagents sets the specifications for most chemicals used in analytical testing. Currently, the ACS is the only organization in the world that sets requirements and develops validated methods for determining the purity of reagent chemicals. These specifications have also become the de facto standards for chemicals used in many high-purity applications. Publications and organizations that set specifications or promulgate analytical testing methods-such as the United States Pharmacopeia and the U.S. Environmental Protection Agency-specify that ACS reagent-grade purity be used in their test procedures. The Eleventh Edition incorporates the "supplements" accumulated over the past eight years, removes some obsolete test methods, improves instructions for many existing ones, and also introduces some new methods. Overall, the safety, accuracy, or ease of use in specifications for about 70 of the 430 listed reagents has been improved, and seven new reagents have been added.

The American Chemical Society Committee on Analytical Reagents is the only organization in the world that sets requirements and develops validated methods for determining the purity of analytical reagents. For the first time, Reagent Chemicals, 10th Edition includes general physical properties and analytical uses for all reagent chemicals, nearly 500 chemicals. Thirty-two new reagents and three new classes of standard grade reference materials are introduced in this edition. In addition, the use of Inductively Coupled Plasma Mass Spectrometry (ICP-MS), which is recognized as the most powerful and flexible trace element technique, is now accepted as an analytical method in the 10th edition. Other improvements include a CAS number index, a separate index for standard grade reference materials, updated atomic weights, frequently used mathematical equations, complete assay calculations with titer values, a tutorial on how to read a monograph, and detailed tables of contents introducing each section.

These recommendations have been developed in the light of technical progress, the advent of new substances and materials, the exigencies of modern transport systems and, above all, the requirement to ensure the safety of people, property and the environment. They are addressed to governments and international organisations concerned with the regulation of the transport of dangerous goods. The Model Regulations cover the classification of dangerous goods, their listing, the use, construction, testing and approval of packagings and portable tanks, as well as consignment procedures such as marking, labeling, placarding and documentation. This sixteenth revised edition contains new provisions (e.g. transport of substances which are toxic by inhalation, requirements for metal hydride storage systems, provisions for fuel cell engines, use of open cryogenic receptacles) and revised provisions (e.g. transport of dangerous goods packed in limited quantities, classification criteria for environmentally hazardous substances, use of electronic data interchange transmission techniques and special provisions for fumigated cargo transport units)."
