5 Foreword (This foreword is included for information only and is not part of ANSI/SSFI SH300 Standard for Testing and Rating Shoring Equipment.) This standard was developed by the Shoring Section of the Scaffolding, Shoring & Forming Institute, Inc. as an assistance and guide to the manufacturers, purchasers, and users of shoring. It provides methods for testing and rating shoring equipment. The methods in this standard are intended to provide a means of comparison only. Due to the wide variety of situation specific factors involved in the use of shoring, it is not possible to develop a method that will apply to all possible situations while still providing useful information upon which comparisons can be made. The ratings derived from the methods in this standard apply to the specific conditions contained in the test procedures. The ratings are not intended to represent actual use conditions, but, rather, they are intended to provide a reference point at which a comparison can be made. Users, purchasers, specifiers, and other interested parties should contact the manufacturer for ratings of specific configurations. SSFI recognizes the need to periodically review and update this standard. Suggestions for improvement should be forwarded to the Scaffolding, Shoring & Forming Institute, Inc., 1300 Sumner Avenue, Cleveland, Ohio, All constructive suggestions for expansion and revision of this standard are welcome. The existence of a Scaffolding, Shoring & Forming Institute (SSFI) standard or recommended procedure does not in any respect preclude any member or non-member from manufacturing or selling products not conforming to the standard or recommended procedure and the SSFI is not responsible for the use of the standard or recommended procedure. iv

6 ANSI/SSFI SH Standards for Testing and Rating Shoring Equipment 1. Introduction This standard contains procedures for testing and rating shoring components and assemblies. These procedures are intended to be used as a guide for industry testing practice and are not intended to supersede procedures set forth in any applicable Federal, State, or local regulations. The Institute believes that adherence to these procedures will yield reliable test results. It takes no responsibility for such results. The methods in this standard are intended to provide a means of comparison only. Due to the wide variety of situation specific factors involved in the use of shoring, it is not possible to develop a method that will apply to all possible situations while still providing useful information upon which comparisons can be made. The ratings derived from the methods in this standard apply to the specific conditions contained in the test procedures. The ratings are not intended to represent actual use conditions, but, rather, they are intended to provide a reference point at which a comparison can be made. Users, purchasers, specifiers, and other interested parties should contact the manufacturer for ratings of specific configurations. Normal shop safety practice and, when applicable, safety precautions described by OSHA or other regulatory agencies should be observed during the administration of these tests. 2. Scope This standard provides methods for testing and rating the following: 3.

Test Methods 5.1 Methods for Testing and Rating Vertical Shoring Posts, Assemblies, and Components Scope: This procedure addresses the compression testing of vertical shoring posts and assemblies, and components Test Setup: The shoring assembly to be tested shall be erected in such a manner as to simulate expected conditions and aligned vertically so that it is not out of plumb more than 1/8 in three feet, but this maximum deviation in the completed structure shall not exceed the diameter or minimum outside width of the vertical member. No greater attempts should be made to adjust the components concentrically than would be expected in actual use Loads: The load shall be applied directly to the load bearing member or members by use of load transfer beams, or cross head of testing machine, or directly by hydraulic jacks in an appropriate testing apparatus or fixture The shoring assembly shall be subject to increasing loads until the ultimate load is reached The rate of loading on the shoring assembly shall not be less than 5,000 lbs. per minute nor more than 10,000 lbs. per minute. The load shall be recorded at load intervals not to exceed 25% of anticipated ultimate load. The load shall be held at the reading interval until the reading has stabilized for a period of one minute The rate of loading on post shores and extension devices shall not be greater than 1,000 lbs. per minute. Load readings shall be recorded at load intervals not to exceed 25% of anticipated ultimate load. The load shall be held at the reading interval until the reading has stabilized for a period of one minute The rate of loading in each test shall remain constant. 4

10 5.1.4 A Series Tests (Towers): Vertical shoring leg load tests shall consist of towers composed of four (4) vertical legs with manufacturer s normal recommended bracing, base plates, and/or adjustment screws. When adjustment screws are being used they shall be extended 12 inches on the top and 12 inches on the bottom. The test specimen shall not be laterally restrained. All four load bearing legs shall be subjected to simultaneous loading until the ultimate load is reached by the weakest leg. Tests performed according to this method are A series tests B Series Tests (Post Shores): Post shores shall be tested individually. Shores may be tested using one of two procedures: 1) At minimum and maximum heights and at every foot throughout the operating range or 2) At minimum and maximum heights. Operating loads for heights between the minimum heights will be determined using a straight line graph between the operating loads at the minimum and maximum heights. The shores may be tested in either a braced or unbraced condition with the individual test data displayed as a graph or chart showing allowable load versus overall height, with the method of bracing, if any, clearly indicated. Loading shall be continued until ultimate load is reached. Tests performed according to this method are B series tests C Series Tests (Extension Devices): Extension devices shall be positioned in or upon legs of the shoring tower and tested in the configuration outlined in paragraph The extension device may be tested extended from the top, bottom or both ends of the legs. Extension devices may be tested using one of two procedures: 1) At minimum and maximum heights and at every foot throughout the operating range or 2) At minimum and maximum heights. Operating loads for heights between the minimum and maximum heights will be determined using a straight line graph between the operating loads at the minimum and maximum heights. The extension devices may be tested in either a braced or unbraced condition with the individual test data displayed as a graph or chart showing allowable load versus overall height, with the method of bracing, if any, clearly indicated. Loading shall be continued until ultimate load is reached. Tests performed according to this method are C series tests D Series Tests (Components): Shoring Component Testing Except for standard shapes and beams of homogeneous materials with established physical chemical properties and constant cross-section, e.g., AISC, all proprietary load-bearing individual shoring components shall be tested independently in a configuration for which they were designed to be used to obtain their ultimate load capacity. When components are supported by other shoring members, a test fixture of design similar to these supporting members shall be used to support the components being tested to assure that the test load can be transferred to the adjacent members. All components, including horizontal bearing components, shall be tested to ultimate load. Tests performed according to this method are D series tests Test results shall be reported on SSFI Vertical Shoring Assembly Test Report Form for Towers (Series A) (See Appendix A), SSFI Vertical Shoring Assembly Test Report Form for Post Shores (Series B) or Extension Devices (Series C) (See Appendix B),or SSFI Vertical Shoring Assembly Test Report Form for Components (Series D) (See Appendix C) including drawing of test setup, failure mode, ultimate total test load, ultimate leg load or component test load as applicable, type of test, rating determined through testing, certification, laboratory report of tested materials, number of tiers, and screwjack extension. 5.2 Methods for Testing and Rating Horizontal Shoring Beams and Assemblies Scope: This procedure addresses the compression testing of horizontal shoring beams and assemblies Test Setup: Horizontal shoring beams shall be tested in pairs or individually, at the discretion of a qualified testing engineer, to obtain their ultimate load.
