Food Equipment Materials
This is the 6th edition of standard published by NSF International.
This Standard establishes minimum public health and sanitation requirements for materials used in the construction of commercial food equipment. The requirements of this Standard are intended to ensure that the composition and surface finish of food equipment materials are such that a material will not adulterate food nor render food equipment difficult to clean and sanitize.
Available in hardcopy and PDF version.
Drinking Water Treatment Chemicals – Health Effect
This standard was published by NSF International in May 2009.
It establishes minimum health effects requirements for the chemicals, the chemical contaminants, and the impurities that are directly added to drinking water from drinking water treatment chemicals. This Standard does not establish performance or taste and odor requirements for drinking water treatment chemicals.
This standard is available in Secure PDF and printed version.
Standard Test Methods for Pitting and Crevice Corrosion Resistance of Stainless Steels and Related Alloys by Use of Ferric Chloride Solution
ASTM standard that contains six procedures (identified as Methods A, B, C, D, E and F), that are used for the determination of the resistance of stainless steels and related alloys to pitting and crevice corrosion when exposed to oxidizing chloride environments. These tests may be used to determine the effects of alloying additives, heat treatment, and surface finishes on pitting and crevice corrosion resistance.
This standard is available in printed and PDF edition.
Standard Test Methods for Measuring Adhesion by Tape Test
This 8 page standard was published on Jun 22, 2009 by American Society for Testing and Materials.
It describes two procedures for assessment of adhesion of coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film. While test method A is more suitable to be performed at job site, method B is good for lab use.
These test methods are used to establish whether the adhesion of a coating to a substrate is at a generally adequate level. They do not distinguish between higher levels of adhesion for which more sophisticated methods of measurement are required.
Note 3 – It should be recognized that differences in adherability of the coating surface can affect the results obtained with coatings having the same inherent adhesion.
This test method is similar in content (but not technically equivalent) to ISO 2409.
In multicoat systems adhesion failure may occur between coats so that the adhesion of the coating system to the substrate is not determined.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This standard is available in English PDF or printed edition.
Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard
ASME released this standard on Jul 30, 2009. It has 238 pages and covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.
- flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanges with rating class designation 2500 in sizes NPS 1/2 through NPS 12, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units
- flanged fittings with rating class designation 150 and 300 in sizes NPS 1/2 through NPS 24, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units
- flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanged fittings with rating class designation 2500 in sizes 1/2 through NPS 12 that are acknowledged in Nonmandatory Appendix E in which only U.S. Customary units are provided
This Standard is limited to:
- flanges and flanged fittings made from cast or forged materials
- blind flanges and certain reducing flanges made from cast, forged, or plate materials
- Also included in this Standard are requirements and recommendations regarding flange bolting, gaskets, and joints.
This standard is available as secure PDF for immediate download or in printed edition, that is usually shipped within 1 or 2 business days.
Engineering Design in Wood
Canadian Standards Association published this 250 page standard in May 2009. It is the ninth revision, while its history spans back to 1959.
This Standard provides criteria for the structural design and appraisal of structures or structural elements made from wood or wood products, including graded lumber, glued-laminated timber, unsanded plywood, oriented strandboard (OSB), composite building components, shearwalls and diaphragms, timber piling, pole-type construction, prefabricated wood I-joists, structural composite lumber products, preserved wood foundations, and their structural fastenings. This Standard employs the limit states design method.
Available in PDF and printed edition.
American National Standard Method for Measuring the Intelligibility of Speech over Communication Systems
A 34 page standard was published in May 2009 by Acoustical Society of America. It was developed as a revision of ANSI S3.2 : 1989.
Provided are three alternative sets of English word that are to be spoken by trained talkers over the comm system under evaluation. Words are carefully selected according to purpose and constraint of the test situation. Trained listeners are made to record words they hear. Resulting intelligibility of the speech of the system is then expressed as the fraction of correctly identified words.
The system may consist of the air and the room or outdoors in face-to-face communications; the equipment and environments used in telephony, public address systems, or ordinary radio; or complex systems of environment, equipment, and air, wire, fiber, radio, and water paths used in some military, space, remote, or emergency communications. The standard specifies test materials that have been thoroughly validated. The standard also specifies methods for selecting and training the talkers and listeners; for designing, controlling, and reporting the test conditions; and for analyzing and reporting the test results.
This standard can be obtained in both PDF and printed edition.
This standard was published in May 2009 by NSF International.
This Standard establishes minimum food protection and sanitation requirements for the materials, design, fabrication, construction, and performance of food handling and processing equipment.
Publication can be ordered in PDF or printed edition.
