    Portable machine and procedure to perform soft impact tests, with large load application area, on fragile materials. Soft impact through an impact element (5) of reduced and variable mass that allows applying with high precision impacts in large load application areas, with variation of the angle of incidence. The impact element (5) comprises a head (51) impactor, of reduced mass, launched from the action of an elastic element, e.g. Compression of a spring, through a variable preload system (2) located on a fixed structure (1). The machine comprises a firing system (4) that is independent of the preload system (2). To make an impact, a certain head type (51) and a preload are chosen. The action is initiated by the firing system (4) which incorporates a rocker (42) and a handle (41). Once the impact is made, a retention system (6) prevents the impactor head (51) from hitting the specimen or specimen (7) to be tested. The retention system (6) incorporates a retaining rubber (63) and a hinge (64). A continuous temporal record of the acceleration, amount of movement and deformation of the glasses is made from the beginning of the impact until the end of the same that allows to know the effect on the glass of the equivalent load.

    Figure 5.- Shows a perspective view of the elements comprising the retention system and the spring. PREFERRED EMBODIMENT OF THE INVENTION
    In view of the aforementioned figures it can be seen how in one of the possible embodiments of the invention the machine that the invention proposes comprises a fixed structure (1), a spring (3), a variable preload system (2) that is independent of a firing system (4), an impact element (5) and a retention system (6).
    The impact element (5) comprises an interchangeable impactor head (51), the preload system (2) comprising a preload cable (21) and a winch (23). The firing system (4) is mechanical and comprises a handle (41) and a rocker (42), so that the action on the handle (41) causes the withdrawal of the preload cable (21), so that the spring (3) pushes the rocker (42), leaving the impact element (5) free.
    As can be seen in views 1a and 1b of Figure 1, the invention allows to determine the soft impact resistance of fragile elements by an impact of the impact element (5). Being a detachable design, the elements can be separated into independent parts according to the figures from 2 to 5, reducing the space occupied by the machine for transport. Once at the test site they are mounted
    or join together a base (11) and a chassis (12) with threaded joints to form a single fixed structure (1).
    Before impact, an impact head (51) is placed, in accordance with the specimen (7) or specimen to be tested, which fixes a main body (52) by means of screws, as shown in Figure 2. The element of Impact (5) has two Teflon bearings to minimize losses when sliding over the guide tube.
    Once the machine is placed in front of the specimen (7) to be tested and with the spring (3) in the rest position, the preload phase is carried out. Using the preload system (2) detailed in Figure 3, the preload cable (21) is passed through a eye bolt (53) comprising the impact element (5) and one end (24) of the cable is hooked preload
    (twenty-one)  on a hook (25), as can be seen in detail A of Figure 3. The hook
    (25)  it is fixed on preload bars (22) that are attached to the base (11).

    Temporary history of impact. An accelerometer is available in the impact element with which the time history is recorded in accelerations, important to know its dynamic behavior, and to obtain the exact equivalent load or momentum. In the specimen to be tested, at least one strain gauge is available to see the
    5 impact effect. Both the number and position of the gauges on the specimen are determined by each specific case of the element to be tested.
    In view of this description and set of figures, the person skilled in the art will be able to understand that the embodiments of the invention that have been described can be combined with multiple
    10 ways within the object of the invention. The invention has been described according to some preferred embodiments thereof, but it will be apparent to the person skilled in the art that multiple variations can be introduced in said preferred embodiments without exceeding the object of the claimed invention.
