  8. 8. Letters Solar plant construction Thank you for your recent article, Solar’s Second Com- ing, in March (pp. 18–21). I completely enjoyed it. Your information was relevant and quite well presented. Perhaps you might consider a follow-up story on how the components and their materials of construc- tion are affecting solar plant efficiency and construc- tion costs. The chemistry and metallurgy that are being used in struts, frames, and storage devices are, in many ways, as interesting as the plants themselves. Again, congratulations on a terrific article. Brian Courtney, Senior PR Executive Schubert Communications, Inc., Downingtown, Pa. Hydraulic Institute seeks input on ANSI pump standards The Hydraulic Institute (HI; Parsippany, N.J.; www. pumps.org), under the approval of the American Na- tional Standards Institute (ANSI; Washington, D.C.; www.ansi.org), is seeking qualified individuals in North America to participate in the review process for the draft of two updated standards: 1. Standard ANSI/HI 4.1-4.6, Sealless Rotary Pumps for Nomenclature, Definitions, Application, Opera- tion and Test. This standard covers the unique features of sealless rotary pumps and includes sections on types and nomenclature; definitions; design and applications; installation, operation, and maintenance; and test. Because of the variety of rotary pump configurations available and the broad range of applications, familiarization withCircle 57 on p. 70 or go to adlinks.che.com/23013-57 Hydraulic Institute Standards ANSI/HI 3.1–3.5 Rotary Pumps for Nomenclature, Definitions, Ap- plication and Operation and ANSI/HI 3.6 Rotary Pump Tests is recommended. 2. ANSI/HI 5.1-5.6, Sealless Rotodynamic (Centrifu- gal) Pumps for Nomenclature, Definitions, Applica- tion, Operation and Test. This standard applies to canned motor pumps and magnetic drive pumps. Excluded from the scope of products are submersible wastewater pumps. The standard includes types and nomenclature; design and application; installation, operation and maintenance; and test. Individuals and organizations directly and materi- ally affected by either standard are asked to contact HI. These parties include pump users and specifiers, producers, standards developers, government agencies, and general interest groups. HI is currently assem- bling a canvass list of all parties interested in review- ing the drafts. These lists will be submitted to ANSI in order to meet its open canvass requirements. To participate in the ANSI/HI canvass, contact Karen Anderson, administrator, Technical Affairs, at kanderson @pumps.org or (973) 267-9700 x 23.
