Order of testing The different product types shall be subjected to the appropriate tests in the order shown in Figure 7. New samples, preferably from the same batch, shall be used for each test. 測試 順序 按圖 7所示的順序在不同的樣品上進(jìn)行相應(yīng)項目的測試 . 并且從同一批產(chǎn)品中挑選新產(chǎn)品進(jìn)行每一項的測試 . Tear resistance test 抗撕強(qiáng)度測試方法 Test method 測試方法 For feeding teats and drinking accessories, place the teat or accessory on a cutting board of at least 10 mm thickness and (70 ??5) Shore D hardness (see Figure 8). NOTE This Shore Hardness is equivalent to 97 IRHDs. 把奶嘴或附件放在一個至少 10mm厚 , D型 邵氏硬度為 (70 ??5)的 平 板上 (見圖 8). 注意 :該邵氏 硬度相當(dāng)於 97 IRHDs. Figure 8 — Position of teat for tear resistance Place the tip of the indentor (see Figure 9) centred over, and at right angles to, the major axis of the teat or accessory, in the region of the waist or neck of the nipple of the teat (. 15 mm to 20 mm) from the tip of the nipple or 15 mm to 20 mm from the end of the accessory. In the case of a feeding teat or drinking accessory not having a circular crosssection, the indentor shall be placed over the flattened surfaces of the neck of the teat or the flattened surfaces of the drinking accessory. At a cross head speed of (10 ??5) mm/min apply a force of (200 ??10) N for (1 ??0,5) s (see Figure 8). If the indentor punctures the ponent, test in accordance with . NOTE: Before use, the tip of the indentor should be visually inspected. If any damage is observed, the indentor should not be used as the results of the test may be affected. 把合金鋼軸的尖端放在 (見圖 9) 奶嘴或附件的 軸線垂直的方向上并位于 奶嘴的腰部或頸部區(qū)域 即 距奶嘴的尖端 15mm到 20mm或距附件的未端 15mm到 20mm 處 . 若 奶嘴或飲水設(shè)備沒有一個圓形截面 , 合金鋼軸 應(yīng)放在奶嘴或飲水設(shè)備 頸部位置 平 坦的 表面上方 . 在十字頭用 (10 ??5) mm/min 的速度 施加 一個 (200 ??10) N 的力並保持 (1 ??0,5) 秒 .(見圖 8) 如合金鋼軸刺破奶嘴 ,則按 測試 . 備注 : 使用前 ,合金鋼軸的尖端應(yīng)目視檢驗 ,如觀察到任何的損壞 ,則不能再使用可能影晌測試結(jié)果的合金鋼軸 .
