Designation F3007 − 19 An American National StandardStandard Test Method forBall Drop Impact Resistance of Laminated Architectural FlatGlass1This standard is issued under the fixed designation F3007; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon ´ indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the destructive ball drop testingof laminated flat glass products intended for use in architecturalglazing applications.1.2 This test method is intended for use as an in-plantquality control test to evaluate the impact performance oflaminated flat glass when a 2.3 kg, 83 mm diameter smoothsolid steel ball is dropped from a user selected height.1.3 This test method is not a substitute for safety glazing testrequirements of ANSI Z97.1 or CPSC 16 CFR 1201.1.4 This test method is applicable to symmetrical andasymmetrical annealed, heat-strengthened, chemicallystrengthened, fully tempered laminated architectural flat glassincluding but not limited to float, patterned, sheet, sand-blasted, grooved, and fritted.1.5 The values stated in SI units are to be regarded asstandard. No other units of measure are included in thisstandard.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.Some specific hazards statements are given in Section 7 onHazards.1.7 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade TBT Committee.2.

Summary of Test Method4.1 In this test method, a single lite of laminated glasseither made to size or cut to size that has been fabricated fromglass meeting the specification of Specifications C1036 orC1048, or both, and quality parameters of Specification C1172is removed from the production process and subjected todestructive ball drop testing. After impact, the retention per-formance of the laminate is recorded and achieved drop heightdocumented.1This test method is under the jurisdiction ofASTM Committee F12 on SecuritySystems and Equipment and is the direct responsibility of Subcommittee F12.10 onSystems Products and Services.Current edition approved April 15, 2019.

United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade TBT Committee.15. Significance and Use5.1 The impact performance of laminated glass varies withthe glass ply thickness, type, and kind as well as the thicknessand type of interlayer used in the overall configuration.5.2 Specific safety properties are required for laminatedglass to meet the safety glazing requirements of ANSI Z97.1and CPSC 16 CFR 1201. Compliance with the minimumquality requirements of Specification C1172 does not consti-tute compliance or assure compliance with the referencedsafety glazing standards.5.3 While this test method does not replace the test require-ments of ANSI Z97.1 or CPSC 16 CFR 1201 safety glazingstandards addressed above, destructive ball drop impact testingdoes provide a method of expeditious in-plant evaluation oflaminated glass products being fabricated.5.4 Impact procedures for testing in accordance with safetyglazing standards ANSI Z97.1 and CPSC 16 CFR 1201 differfrom this ball drop test method; however, the penetrationresistance of a single laminated lite can be determined and usedfor quality control purposes.6. Apparatus6.1 A smooth solid steel ball weighing 2.3 6 0.1 kg.6.2 A support frame constructed similar to Fig. 1 which iscapable of supporting a laminate around the edges whileallowing a 260 by 260 6 6 mm square for the ball to drop onto.6.3 A mechanism for ensuring the unimpeded drop of theball from rest onto the test specimen within 25 mm of center.6.4 A mesh with a designated opening size, determined bythe authority having jurisdiction, may be draped inside orunder the box to gather or catch any disengaged glass. Thismesh may act as a sieve to assess the size of disengaged glassshards after impact.7. Hazards7.1 Warning Test impact is intended to result in glassfracture. Proper glass handling safety gear should be worn atall times during specimen handling, testing, evaluation, anddisposal.8. Test Specimen Size8.1 Test specimen size is 305 6 10 mm by 305 6 10 mm.9. Procedure9.1 Record the minimum thickness of the specimen.NOTE 1The thickness of the specimen shall be measured at themidpoint of the four sides within 1 in. of the edge. Multiple measurementscan be made at various locations on the glazing. The thinnest thicknessfrom all measurements shall be reported.FIG. 1 Holding Fixture for Drop Test – Cut-away Side ViewF3007 − 1929.2 The specimens shall be conditioned at 24 6 5°C for atleast 4 h, immediately prior to the performance of the ball droptest.NOTE 2Very thick specimens may require conditioning for longerperiods of time.9.3 Record the weight of the laminate prior to impact.9.4 Record the specimen temperature at the surface to beimpacted.9.5 Place the specimen on the support frame. Specimen maybe clamped to retain it in the frame during testing.9.6 Raise the steel ball to the selected height ensuring thatupon release from an at-rest position, the ball will dropunimpeded and impact the center of the specimen within 25mm of center.9.7 Within a 5 s interval after impact, determine the pen-etration resistance/retention characteristics of the specimenusing Table 1.9.8 The impacted specimen remaining in the test frame shallbe weighed to determine the weight of material loss fromimpact.9.9 A specimen is deemed a fail if particles which havedetached from the test specimen up to 3 min after impact intotal weigh more than a mass equivalent to 15.5 in.210 000 mm2 of the original test specimen. The single largestparticle shall weigh less than a mass equivalent to 6.82 in.24400 mm2 of the original test specimen. Detached individualparticles less than the mass equivalent of 1 in.2650 mm2 shallbe excluded from the fragment analysis.9.10 Record laminated glass construction, temperature, pro-duction date, drop height, and result see Section 11.9.11 Repeat test on at least two additional 305 by 305 610 mm specimens of the same configuration and production lotat the same or elevated drop heights.10. Interpretation of Results10.1 The results are interpreted according to Table 1.10.2 Three specimens from the same lot shall be tested andall three shall exhibit passing retention characteristics.11.
