一、沙發靠背耐久性試驗，沙發靠背耐久性試驗供應商測試目的 / Scope 這一試驗方法是模擬日常使用條件下，檢驗沙發對長期重復性載荷的承受能力。試驗沙發的座、背和扶手的耐久性, 試驗時將一定形狀、質量的加載模塊，以規定的加載形式、頻率，分別對座、背和扶手表面重復加載。座面載入力是750牛頓背面載入力是400牛頓測試周期: 25000次至200000次 The principle is to determine the strength of the structure of sofa by applying to various parts loads or forces simulating normal functional use, as well as acceptable mis-use. Force apply for seat fatigue : 750 N Force apply for back fatigue: 400 N Test cycles- 25000 to 200000 cycles.
