Performance and finishes • General information <br />318 • • Technical data manual • Book Rev. 08/30/17 • Page Rev. 06/08/17 <br />General information <br />The use of product specifications does not always give a true <br />comparison of the products that are used in today's market <br />place. As an example, one manufacturer may use a different <br />reinforcement in a product which is not included in the product <br />specification. The reinforcement although superior in design <br />and function may be deemed unacceptable using a product <br />specification. <br />Established and recognized industry performance tests provide <br />the truest method of comparing products. Performance test <br />results give an accurate evaluation of the products being <br />compared. <br />Manufacturers do not write performance tests. Industry <br />associations, testing laboratories and standard associations <br />write them. Included are: <br />• Underwriters Laboratories Inc (UL) <br />• Intertek Testing Services / Warnock Hersery (ITS/WHI) <br />• National Fire Protection Association (NFPA) <br />• American Society for Testing and Materials (ASTM) <br />• Steel Door Institute (SDI) <br />• Door and Hardware Institute (DHI) <br />In most cases after the performance test is written many <br />people, groups and associations review the resulting <br />performance specification before it becomes a recognized <br />standard. As a result, the performance specification is <br />accepted as the true measuring tool for products. <br />Performance tests <br />The pages included in this section describe the tests that have <br />been conducted on the various Steelcraft products. Copies of <br />the test report are available upon request through Steelcraft <br />distributors. <br />Errors and omissions <br />Every effort has been made to insure the accuracy and <br />completeness of the Steelcraft Spec Manual. This manual is for <br />use by qualified persons only. The information herein is subject <br />to some interpretation, and from time to time the Spec sheets <br />will be updated whenever it is deemed necessary as new tests <br />are conducted, new products are introduced and as <br />specifications are revised. For these reasons and because of <br />the nature and scope of the subject, the Steelcraft <br />Manufacturing Company and its employees can assume no <br />responsibility or liability for the absolute accuracy of the <br />material contained herein or its use.

These performance <br />standards include both cycle and twist test requirements. In <br />both tests the door is subjected to stresses that exceed those <br />found in typical applications. During and at the end of the test, <br />the technician is looking for metal fatigue, weld breakage, <br />panel separation, delaminating, reinforcement failure and any <br />other failures that occur. <br />ANSI/SDI A250.8-20 14 “Recommended Specifications for <br />Standard Steel Doors and Frames” specifies the minimum <br />number of cycles for doors: <br />Door Gauge Cycles Tested <br />20 gauge door 250,000 (Level C) <br />18 gauge door 500,000 (Level B) <br />16 and 14 gauge door 1,000,000 (Level A) <br />ANSI A250.4 <br />The door is mounted in a frame and is pushed to an open <br />position of 60 degrees. The door is then closed using a <br />conventional door closer. <br />Cycle Test: The cycle is repeated approximately 15 times per <br />minute. The forces placed on the door in this test are <br />determined by adjusting the closer speed. <br />Twist Test: At intervals prescribed by the test procedure, three <br />corners of the door are clamped in place and a prescribed load <br />applied to the fourth corner. <br />Steelcraft doors tested in accordance with ANSI A250.4 for <br />extended life cycle. <br />Door Series Cycles Tested Frame Series <br />L18 5 million MU16 <br />L16 5 million MU16 <br />L14 3 million F16 <br />B18 3 million F16 <br />B16 3 million F16 <br />CE18 2 million DW16 <br />This test simulates a door in actual operation. Steelcraft’s L <br />Series door construction was successfully tested in accordance <br />With ANSI/SDI A250.4 for 5,000,000 cycles and 103 twist <br />tests conducted at specified intervals throughout the cycle <br />test. <br />All tests are UL certified.General InformationFramesDoorsLights and LouversElevationsHurricaneSpecialtyHardwareFire Rated ProductsPerformanceArchitecturalVariationsVariationsTornadoHome <br />DocuSign Envelope ID: 97A9508F-537F-4A89-96AD-A82F9ABD3708
