In the current review proces
11、s, thisseries of standards is being updated and revised in format. Many of the standards inthis series, but not all, also exist as standards of the International Organization forStandardization (ISO). The current updates and revisions are in accord with thatdone for the ISO standards. In an effort t
12、o promote the concept of international stan-dardization, references to ISO standards have been left in place. Suggestions for the improvement of this standard will be welcome.

Genera
17、l test methods and procedurescited in this standard are compiled in Parts 1 and 8 of ISO 10349.This standard is intended for use by individuals with a working knowledge of analyti-cal techniques, which may not always be the case. Some of the procedures utilizecaustic, toxic, or otherwise hazardous c
18、hemicals. Safe laboratory practice for thehandling of chemicals requires the use of safety glasses or goggles and other protec-tive apparel such as rubber gloves, face masks or aprons where appropriate. Normal precautions required in the performance of any chemical procedure shall beexercised at all
19、 times, but care has been taken in this standard to provide warningsfor hazardous materials. Hazard warnings designated by a letter enclosed in anglebrackets, , are used as a reminder in those steps detailing handling operationsand are defined in ISO 10349-1. More detailed information regarding haza
20、rds, han-dling, and use of these chemicals may be available from the manufacturer.0.2 This standard provides chemical and physical requirements for the suitability of aphotographic-grade chemical. The tests correlate with undesirable photographic ef-fects. Purity requirements are set as low as possi
21、ble consistent with these photo-graphic effects. These criteria are considered the minimum requirements necessaryto assure sufficient purity for use in photographic processing solutions, except that ifthe purity of a commonly available grade of chemical exceeds photographic process-ing requirements
