Wayne Yancey Senior Member Username: wayne_yancey Post Number: 11 Registered: 01-2008 Posted on Friday, February 29, 2008 - 03:33 pm:    DIN Standards - Germany DIN Deutsches Institut für Normung is a private, non- profit-making association and was founded in 1917. Relations between DIN and Government, both on the Federal and the Länder levels, are regulated by contracts. DIN standards are recognized by industry, trade, labour unions, consumers, Government and jurisprudence as accepted rules of technology. DIN standards are established according to the following eight principles: Standards are voluntary in nature. Standards projects and drafts are made available for public comment. All interested parties can participate. DIN standards form a unified and consistent whole. They keep to the technical matter in hand. They are geared to technological development. They are matched to economic conditions. They are geared to the benefit of the community as a whole. Internationalist in spirit, DIN strives towards world trade that is free of technical barriers. To promote the implementation of standards, DIN organizes training courses, regular exchange of experience among standards practitioners. DIN's publishing house, Beuth Verlag, provides 52 % of DIN's total budget through its sale of standards and associated technical literature in printed form, on microform and on electronic media.

Indoor surfaces for multi-sports use. or BS EN 14904:2006 Surfaces for sports areas. Indoor surfaces for multi-sports use. Specification British-Adopted European Standard / 30-Jun-2006 MFMA PERFORMANCE CHARACTERISTICS GUIDE Northern hard maple has often been called nature's perfect flooring surface. MFMA Northern Hard Maple is produced from trees grown north of the 35th parallel where shorter growing seasons and longer winters produce maple with closer, more uniform grain. In a floor, MFMA northern hard maple exhibits flexibility, resilience, durability, finishability and low-demand maintenance. Athletic performance is enhanced by its hard-but-resilient character. Subfloor systems further enhance maple's natural shock absorption and area elasticity. Performance Standards -- An Introduction Since 1897, the Milling Company Manufacturer members of the MFMA have dedicated their production of northern hard maple flooring to the highest levels of quality. Year after year, installation after installation, the MFMA Grading Rules have ensured consistent quality. Because of their prominent position in the athletic flooring market, the MFMA mills collectively continue to lead by establishing performance standards for sports floors. Performance characteristics for floors: shock absorption, ball bounce, rolling load, etc. have been engineered into flooring systems for years. Today, however, more emphasis is placed on specific performance characteristics that can be measured by generally accepted methods and numbers. The MFMA mills engineer performance characteristics into their flooring systems for the benefit of those who will select and use them. In some instances, standards of performance may be specified to provide particular characteristics. For most flooring systems, the areas of performance offered by the MFMA mills are those contained in the DIN Standard 18032 Part 2. As an organization representing the worldwide sports flooring industry, the MFMA has fully accepted the areas of performance included in the DIN Standard 18032 Part 2, as desirable characteristics. This guide will provide you with a brief history of DIN and a thorough background on the following performance characteristics: Shock Absorption; Vertical Deflection and Area of Deflection; Ball Bounce; Surface Friction; and Rolling Load. MFMA mills accept DIN values for each of these characteristics as industry minimums specifically for performance-engineered multipurpose flooring systems. MFMA is currently researching the interdependence of performance criteria and relative performance levels to determine acceptable performance ranges for each characteristic. Our intent with this guide is to help you in your selection of those performance characteristics that are more appropriate for the activities being performed on your floor. It is important to note that this guide is not a technical explanation of the DIN Standard, nor is it a blanket endorsement of all of the DIN numbers. In fact, certain activities conducted on MFMA maple floors may be better served by an MFMA flooring system which exhibits a performance characteristic value exceeding or falling below the DIN requirement. MFMA is investigating the long-term effects of performance characteristic values on athletes/users, flooring system longevity, and the relevance of variances in DIN testing data within individual systems. As research continues in each area, MFMA seeks to establish well-rounded performance criteria for all floors that balance technical standards and measurement methods with practical design and flooring system life-cycle concerns. DIN History DIN Standards were initially developed by the Otto Graf Institute, affiliated with the University of Stuttgart in Stuttgart, Germany. Using the "Artificial Athlete Berlin" apparatus, which simulated the response of a typical participant's interaction with a sports surface, various tests were applied to point elastic (synthetic), area elastic (wood), combination and mixed flooring systems. The primary objective was to develop test methods and standards that would apply to government-funded projects in Germany. When a particular flooring system meets the DIN Standard 18032 Part 2, it has been tested according to specific procedures and has met all of the requirements included in the Standard. There are now several testing facilities that can test flooring systems in accordance with the DIN Standards, and more specifically, DIN 18032 Part 2. For additional information on DIN testing procedures, contact any of the MFMA Manufacturer members for additional information on their system(s) that have been tested in accordance with the DIN Standard 18032 Part 2.

Baker, RA, CSI, CCS, CCCA, LEED AP (Unregistered Guest) Unregistered guest Posted on Monday, March 03, 2008 - 06:18 pm:    Wayne, You seem to be well-versed in standards from other parts of the world, so maybe you can answer this question: is there a (relatively) simple way to correspond ASTM standards listed in most spec sections to an equivalent British Standard? We're coming up on time to print a DD set of docs and now we're being asked to change our ASTM references to British Standards for a project in the UAE. Is it as simple as finding a source for the British Standards?

It's tough enough when US manufacturers choose two different ASTMs to measure the same property. Ralph Liebing, RA, CSI Senior Member Username: rliebing Post Number: 792 Registered: 02-2003 Posted on Tuesday, March 04, 2008 - 06:50 am:    NOT TO TAKE WAYNE'S THUNDER, BUT MY EXPERIENCE IS THAT THERE IS NO SUCH CORRELATION. BSs ARE WRITTEN IN A DIFFERENT FORMAT, AND ARE PACKAGED IN A DIFFERENT MANNER. UPON INQUIRY FOR A CANADIAN PROJECT, THE GOVERNMENT AGENCY UP THAT NOTED THERE WAS NO DOCUMENT THAT RELATED THEIR STANDARDS TO OURS. MOST FRUSTRATING! ALSO MIGHT MENTION THAT THIS IS ALSO TRUE OF BUILDING CODES-- THEIR WHOLE APPROACH IS FAR DIFFERENT FROM OUR [MORE CONCEPTUAL] Wayne Yancey Senior Member Username: wayne_yancey Post Number: 13 Registered: 01-2008 Posted on Tuesday, March 04, 2008 - 03:21 pm:    Ann, I have the same situation you face. I have not been given the green light to commence the conversion but I think several months in the UK is a good start. I agree with Ralph. The National Building Code of Canada and British Building Regulations are more objective based that the IBC. Sorry I cannot be of more assistance.

My advise is for the US firm to do schematics and DD and then hand off to a local engineer. In the case of projects in Germany they have Proof Engineers who check the design and they expect the calculations to be formatted just so. If you must carry the project through construction then at least bring on board a local design professional to guide you through the process.
