Test set-up In Germany the production of laminated safety glass is continuously tested by a ball drop test according to DIN 52338, that is the most commonly performed . Subsequently, its category is defined based on the height of fall and types of damage. The impact resistance of the window has been the subject of several studies, experimental mechanical analysis of traditional in-service glass windows subjected to dynamic tests ( modal analysis) and hard body impact was studied in [9, 10]. 2.3 Blast resistance Impacts on the structural glass commonly have two types: soft body impact such as manual hit or falling [8], [9], [10], or hard body impact like axe attack or windborne debris hit [11], [12]. The structural calculations or experimental study on the soft body impact on the glass products have reached a high level of accuracy [13] , [14] , which .
Annex A1 describes test methods for testing impact-resistant sheetrock and other products for Hard Body Impact Resistance. ASTM C1629 makes reference to three other test methods for abuse resistance: ASTM E695 for Soft Body Impact, ASTM D4977 for Abrasion resistance, ASTM D 5420 for Indentation Resistance.testing to determine their impact resistance, which must then be matched to the use category of the particular façade. Test Standards Guidance and test methods for impact resistance come from a variety of different sources; however, they are broadly similar using either steel balls for Hard Body impacts or canvas4.1.2 Principle of the test The hard body is made of a plain steel spherical ball of 50 mm diameter with a link-bolt, of 0,5 0,02 0 + kg mass, which is designated as D 0,5. The impact is provided by pendulum action of the hard body D 0,5. The device used carry out the test is shown in Figure 1. This is a preview of "BS EN 13330:2013". Testing standards such as ASTM F3007 [23] and BS EN 356 [24] suggest two types of hard body impactors, i.e. a 2.3 kg steel ball and a 4.11 kg steel ball, to simulate accidental impacts and vandal attacks, respectively. However, measuring the impact force using a spheroidal impactor presents a difficulty.

The test to determine the hard body impact strength, carried out following the Brazilian standard NBR 15,845–8:2015 , is the recommended method for determining the hard body impact strength of finished rock products intended for use as building cladding materials.Impact Damage Hard-body (tools, doorknobs, or other hard objects) and soft-body (human) impact with enough force to penetrate through the partition into the wall cavity. This often causes damage that requires replacing panel sections and is costly to repair. This also can be potentially unsafe in fi re-rated partitions if not repaired promptly. The impact resistance is determined by only one hard body impact test, corresponding with a vertical drop. The test result is expressed as a type of damage or without damage. The resistance to low temperatures is mentioned by testing the hard body's impact resistance at the temperature of −20°C.These are based on the ACR soft body impact test, together with additional hard body impact tests, and limit the size of shards of glass falling from broken panes, to minimise risk to any personnel beneath. CWCT, working in conjunction with ACR, have been able to develop a simplified test method, and also a “deemed to satisfy” solution, for .

Despite the simplicity of the soft body impact test, to depict the target impact resistance performance or failure threshold, it is impractical to run tests covering all the potential outcomes that could occur during an impact event. . The hard-sphere approach and the soft-sphere approach are the two primary discrete simulation techniques . For example, if you choose to utilize method 2 from Section 403.2.3.2, the use of a single gypsum panel will need to have a Soft Body Impact Classification Level 2 and a Hard Body Impact Classification Level 3 to meet the Code requirements. See the 2018 IBC configuration in Figure 2. In comparison to the fragmentation test and the soft-body impact (which provide purely qualitative data), the bending strength gives a specific number that can be used further in design. . As shown in the literature [20,37,43,44,45], a hard-body impact lasts much shorter (less than 1 ms) in comparison to the soft-body impact. Therefore, an .
