Document Center Inc. The performance of special tests covering this aspect may be desirable. Whenever given uniformly distributed loads are to be resisted by a railing system or rail in accordance with governing specifications, codes, and standards, the effects of such uniformly distributed loads on the member stresses shall be determined by calculation and the corresponding concentrated loads shall be given consideration during testing and data evaluation. The values given in parentheses are for information only.

A number in parentheses indicates the year of last reapproval. The performance of special tests covering this aspect may bedesirable. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

Typical floor-mounted railings are shown in Fig. The testing device shall be of sufficientcapacity to prevent yielding of its various components andshall insure that the applied load remains essentially parallel tothe relevant axis of the assembly during testing. Loadcontact points against the test specimen shall be a maximumwidth of 2 in. These devices shall have sufficient mea-surement capability to indicate the displacement throughout thetest range.
Test Selection6. Test Specimens9. If the purpose of the test is to determine compliance orperformance as installed in a specific field example, the span ofthe gate should be as in the field installation. The test results shallstate the minimum required edge distance to ensure adequateperformance.
The specimen installation, including the post spacing,shall be the same as the actual or anticipated field installation. A guardrail specimen shall have a minimum of three posts ifthis is in line with the actual field installation simulated. The failure must berecorded. If testing is conducted for purposes of determiningcompliance with a performance standard or to determineperformance of the complete railing system or any element ofthe railing system, the failed component or connection may notbe replaced.
The test series continues as defined in The test loadshall be applied at the intersection of the horizontal and verticalcenter lines of the in-fill, unless specified otherwise by theperformance specification or the purposes of the test. If it isdetermined that another location will yield lesser results, thatposition should be used instead of the indicated intersectionpoint of the center lines.
Record deflection of the in-fill at thepoint of maximum deflection of the in-fill. Required vertical and horizontal test loadsshall be applied separately and sequentially, unless otherwiserequired by the performance specification or to meet thepurpose of the test.
Record the deflection at mid-span duringeach test. Apply required vertical and hori-zontal test separately and sequentially, unless otherwise re-quired by the performance specification or to meet the purposeof the test.
The required concentrated test load shall be appliedat the following three critical locations: rail midspan betweenposts, top rail adjacent to a post maximum 3 in. Test loads are to be applied and deflectionrecorded sequentially, one location at a time. The load appliedon the rail adjacent to the post can be applied to the oppositepost from which the top-of-post test was performed on. In thecase of swing gates, if the structure of the gate requires locatingthe test load more than 3 in.
Record thedeflection at the point of application of the load. Load Application Warning—Possible injury topersonnel and damage to the test equipment and instrumenta-tion prior to, during, and after load application by anyunexpected release of potential strain energy accumulatedduring testing can occur and must be given consideration. Warning—If tests are conducted in a structure and not in atesting laboratory, exercise caution against unwanted damageto the building, its components, and its finish.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Remember me for one month. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
