CO2 Ultum Nature Systems

A professional grade CO2 delivery system for planted aquariums. Featuring two gauges, the UNS Pro Regulator allows the output pressure and available CO2 levels to be monitored. This regulator comes equipped with a dual stage, failsafe mechanism for added safety measures and includes a bubble counter for simple, yet precise management of CO2 levels. Development of the UNIFIED NUMBERING SYSTEMThe UNS designation system has been a highly successful venture from many standpoints. It has provided satisfactory solutions to the six problem areas discussed earlier in this article. Metals and Alloys in the Unified Numbering System, published jointly by ASTM and SAE, lists over 5000 UNS des - ignations in the recently published ninth edition. It

Standard Practice for Numbering Metals and Alloys (UNS)Sep 09, 2009 · for an all-encompassing system, the UNS numbers are intended to identify metals and alloys that are in more or less regular production and use. A UNS number will not ordinarily be issued for a material that has just been conceived or that is still in only experimental trial. 1.2 The UNS provides a means of correlating many nation-

The Unified Numbering System - Rolled Alloys, Inc.

The Unified Numbering System (UNS) is an alloy identification system created in the early 1970s and formalized with the issuance of joint standard ASTM E527 and SAE J1086 in August of 1974. The system assigns numbers to alloys on the basis of composition only. There is no definition of mechanical or other properties. UNS Standard Designation for Wrought and Cast CopperThe Unified Numbering System (UNS) is the accepted alloy designation system in North America for wrought and cast copper and copper alloy products. The three-digit system developed by the U.S. copper and brass industry was expanded to five digits following the prefix letter C and made part of the Unified Numbering System for Metals and Alloys. UNS-1Lw SBAS-Flight Management SystemThe UNS-1Lw features a standard set of I/O capabilities for interface with essential components of the flight deck. The system is comprised of a 4- or 5-inch Flat Panel Control Display Unit (FPCDU) along with a remotely mounted Navigation Computer Unit (NCU).

Unified Numbering System - an overview ScienceDirect

The UNS provides a method for correlating the metal and alloy numbering systems developed by various technical associations. It has been developed to avoid designating more than one number for the same metal or alloy, and to avoid designating the same number for Unified Numbering System for Ferrous Metals and AlloysThe Unified Numbering System (UNS) for Metals and Alloys is established to correlate several internationally used alloy and metal numbering systems, which are now commonly used by trade associations, societies and producers and users of alloys and metals.UNS - Unified Numbering System - Engineering ToolBoxThe Unified Numbering System - UNS - was developed by ASTM and SAE to correlate different numbering systems for commercial metals and alloys. The UNS number is not a specification - it is an identification number for a metal or alloy specified elsewhere. The UNS numbering categories are Ferrous metals and alloys
