5) Standards Uni from 10805 to 10809

  • Uni 10805-1999: Railings, balustrades or prefabricated parapets - Determination of static load resistance of columns and columns.
    The standard defines a test method for determining mechanical resistance to static loads of columns and columns that are part of railings, balustrades or parapets of any material. The rule applies to prefabricated, unplanned balustrades, balustrades or parapets, and / or installed with the help of masonry works.
  • Uni 10806-1999: Railings, balustrades or prefabricated parapets - Determination of mechanical resistance to distributed static loads.
    The standard defines a test method to determine the mechanical strength of distributed static loads of railings, balustrades or parapets of any material.
    The rule applies to prefabricated, unplanned balustrades, balustrades or parapets, and / or installed with the help of masonry works.
    This standard defines the mechanical strength test method for distributed static loads of prefabricated railings, parapets and balustrades that function as fall protection As can be seen, the standard dates back to 1999, the year in which the ministerial decree of January 9, 1996 was in force, while the criteria for calculating resistance are still valid, the values ​​of the actions determined by the rules in force should be used.
  • Uni 10807-1999: Railings, balustrades or prefabricated parapets - Determination of mechanical resistance to dynamic loads
    The standard defines a test method to determine the mechanical strength of the dynamic loads of railings, balustrades or parapets of any material.
    The rule applies to prefabricated, unplanned balustrades, balustrades or parapets, and / or installed with the help of masonry works.
    This Standard defines the test method for the determination of the mechanical resistance to the dynamic loads of prefabricated railings, parapets or balustrades, which have fall protection function, using the pendulum test with a mass device equal to kg 50 and a variable fall height to the intended use As can be seen, the standard dates back to 1999, the year in which the ministerial decree of January 9, 1996 was in force, while the criteria for calculating resistance are still valid, the values ​​of the actions determined by the rules in force should be used.
  • Uni 10808-1999: Railings, balustrades or prefabricated parapets - Determination of mechanical resistance to static loads on panels
    The standard defines a test method to determine the mechanical resistance to static loads concentrated on the railings, balustrades or parapets of any material.
    The rule applies to prefabricated, unplanned balustrades, balustrades or parapets, and / or installed with the help of masonry works.
  • Uni 10809-1999: Railings, balustrades or prefabricated parapets - Dimensions, mechanical performance and sequence of tests
    The standard establishes the dimensional characteristics and mechanical performance of railings, balustrades or prefabricated parapets, depending on their intended use and installation environment. It also establishes the functional sequence of performance characterization tests.
    Of particular interest this standard defines some of the essential requirements for parapets, among which it is important to cite:
    §3.2 Scalability
    The various elements of railings, balustrades or parapets must be arranged in such a way as to disadvantage the climbing.
    In particular, in the case of balustrades, balustrades or parapets made of horizontal bands, the following dimensional requirements shall be considered:
    The bottom of the railing, parapet or balustrade must be blind and with the inner face having a straight profile and perpendicular to the ground plane;
    The upper edge of the lower end must be at least 500 mm from the step of the step to the railings, and from the balustrade for balustrades or parapets
    For a minimum height of 700 mm from the step of the step for the railings and the tread for balustrades or parapets, the additional bands must be free from light not more than 20 mm it is important to point out that the rule excludes the possibility of making railings with horizontal elements except with lights between the elements below 20mm in the first 70cm from the treadmill, or alternatively with blind protection (glass or sheet) for the same height as to prevent climbing, no observation can be detected on the use of handrails disassembled with the projection of the parapet in fact it is not possible to consider such a sufficient solution to prevent scalability.
    §3.3 Invertability
    Railings, balustrades or parapets shall be able to be crossed at any point by a sphere of 100 mm in diameter
    §4 MECHANICAL PERFORMANCE

    ...

    §4.2 Mechanical resistance to distributed static loads
    Prefabricated railings and balustrades, which have fall protection function, must be subjected to the test defined in 10806, at the end of the test no breakage or degradation may be encountered which could compromise the user's safety requirements for the produced at project stage. However, the deformation arrow under load must not be greater than 2% of L where L is the total sample length, and in any case it must not be more than 60mm Maximum residual deformations equal to 0.2% L, but not more than 6mm, are allowed
    §4.3 Mechanical resistance to dynamic loads
    Prefabricated balustrades and balustrades, with a fall protection function, shall be subjected to the test defined in UNI 10807.For the end of the test, there shall be no breakage or degradation that may compromise the user's safety requirements produced at project stage.
