Ventilation for Acceptable Indoor Air Quality

Developed by American Society of Heating, Refrigerating, and Air-Conditioning Engineers, ASHRAE 62.1 was published in the summer of 2010.

ANSI/ASHRAE Standard 62.1-2010 supersedes Standard 62.1-2007. It is ASHRAE’s standard for indoor air quality for commercial buildings. The 2010 revision adds new minimum filtration/air-cleaning requirements, minimum requirements for when ventilation systems must be operated, and a Natural Ventilation Procedure. Other revisions include a more robust IAQ procedure, demand-controlled ventilation system design requirements, requirements for separation of intakes and exhausts, and ventilation rates and occupancy categories.

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.

Included are:

• 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.

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.

Process Piping

This 258 page standard was published on Mar 31, 2009 by American Society of Mechanical Engineers.

This Code is applicable to piping in gaseous and liquid hydrogen service and to pipelines in gaseous hydrogen service. This Code is applicable up to and including the joint connecting the piping to associated pressure vessels and equipment but not to the vessels and equipment themselves. It is applicable to the location and type of support elements but not to the structure to which the support elements are attached. This Code is presented in the following parts:

(a) Part GR — General Requirements. This part contains definitions and requirements for materials, welding, brazing, heat treating, forming, testing, inspection, examination, operation, and maintenance.

(b) Part IP — Industrial Piping. This part includes requirements for components, design, fabrication, assembly, erection, inspection, examination, and testing of piping.

(c) Part PL — Pipelines. This part sets forth requirements for components, design, installation, and testing of hydrogen pipelines.

It is required that each part be used in conjunction with the General Requirements section but independent of the other parts. It is not intended that this edition of this Code be applied retroactively to existing hydrogen systems.
