Scope

5.1 This test method is a standard procedure for determining structural performance under cyclic air pressure differential. This typically is intended to represent the long-term effects of repeated applications of wind load on exterior building surface elements or those loads that may be experienced during a hurricane or other extreme wind event. This test method is intended to be used for installations of window, curtain wall, and door assemblies for which the effects of cyclic or repeated loads may be significant factors in the in-service structural performance of the system and for which such effects cannot be determined by testing under a single application of uniform static air pressure. This test method is not intended to account for the effect of windborne debris. This test method is considered appropriate for testing unique constructions or for testing systems that have insufficient in-service records to establish their performance under cyclic loading.

5.1.1 The actual loading on building surfaces is quite complex, varying with wind direction, time, height above ground, building shape, terrain, surrounding structures, and other factors. The resistance of many window, curtain wall, and door assemblies to wind loading is also complex and depends on the complete history of load magnitude, duration, and repetition. These factors are discussed in ASCE/SEI 7 and in the literature (1-12)⁵.

5.2 This test method is not intended for use in evaluating the adequacy of glass for a particular application. When the structural performance of glass is to be evaluated, the procedure described in Standard Test Method E997 or E998 shall be used.

5.3 The proper use of this test method requires knowledge of the principles of pressure and deflection measurement.

5.4 Two types of cyclic air pressure differentials are defined: (Procedure A) Life cycle load (X1.1) and (Procedure B) Wind event load (X1.2). When testing under uniform static air pressure to establish structural performance, including performance under proof load, Standard Test Method E330/E330M applies. Consideration of windborne debris in combination with cyclic air pressure differential representing extreme wind events is addressed in Standard Test Method E1886 and Standard Specification E1996.

5.5 Typical practice in the United States for the design and testing of exterior windows, curtain walls, and doors has been to consider only a one-time application of design wind load, increased by an appropriate factor of safety. This design wind load is based on wind velocities with actual average probabilities of occurrence of once in the design life of the structure. The actual in-field performance of such assemblies, however, is dependent on many complex factors, and there exists significant classes of applications where the effects of repeated or cyclic wind loading will be the dominating factor in the actual structural performance, even though the magnitudes of such cyclic loads may be substantially lower than the peak load to which the assembly will be subjected during its design life. Examples of assemblies for which the effects of cyclic loading may be significant are included in Appendix X2.

5.5.1 When cyclic load effects are significant, the actual in-field performance of the assembly will depend on the complete load history to wh......<......
