Main Technical Content: 1. Scope This document specifies the technical requirements, test conditions, test methods, test cycles, and application of test results for air spring and oxygen spring aging test equipment (hereinafter referred to as "test equipment"). This document applies to the performance testing of air spring and oxygen spring aging test equipment. 2. Normative Reference Documents This document does not have any normative reference documents. 3. Terms and Definitions The following terms and definitions apply to this document: 3.1 Working Space The portion of the test equipment that can maintain the specified test conditions within the prescribed deviation range. [Source: GB/T 5170.1–2008, 3.2.2] 3.2 Resolution The smallest change in the measured value that results in a perceptible change in the corresponding displayed value. [Source: JJF 1001–2011, 7.14] 3.3 Temperature Deviation The deviation between the highest and lowest temperatures measured at various measurement points in the working space within a specified time period and the set temperature, under stable conditions of the test equipment. [Source: GB/T 5170.1–2008, 3.2.4] 3.4 Temperature Fluctuation The variation in temperature at any point within the working space over a specified time interval under stable conditions of the test equipment. [Source: GB/T 5170.1–2008, 3.2.6] 3.5 Temperature Uniformity The maximum difference between the temperatures of any two points in the working space at a given instant under stable conditions of the test equipment. [Source: GB/T 5170.1–2008, 3.2.8] 3.6 Pressure Deviation The deviation between the highest and lowest pressures measured at the center measurement point in the working space within a specified time period and the set pressure value under stable conditions of the test equipment. 3.7 Pressure Sealing The change in pressure within the working space over a specified time period under stable conditions of the tes
