TS 57 Paper-like Product Test 紙品測試Page 4 of 4Test Specification #:TS 57Test:Paper-like Product Test 紙品測試Reference:McDonalds Specification Objective:The purpose of this test is to assure that paper-like or paperboard products are wettable and have low strength when wet to minimize the potential for choking. 此測試是確保紙品或紙板是可被濕潤 及 濕後會成低Application:Any paper-like product, which has no plastic or metallic lamination on its surface and is made from natural vegetative fibers, is subject to this test. Thin less than or equal to 0.3 mm (0.012 in.) thick uncoated paper products made from natural vegetative fibers are exempt from this test. For the purpose of this specification, plastic or metallic laminated paper-like products are defined as paper, paperboard, or paper-like products that are fused with thin plastic or metallic sheet(s). Paper, paperboard, or paper-like products treated with pigment/binder dispersions, including glue, are considered as coated paper, paperboard or paper-like products, and they are subject to this test. Paper-like products that fail TS 57, regardless of their thickness, will be subjected to the McDonalds Core Test Specification TS 37 Bite/Tear Test (except for the precondition part) after being immersed in water for 5 min. If factory applied paper-like labels fail TS 57, the labels will be subjected to the McDonalds Core Test Specification TS 60 Removability Test of Factory Applied Labels.任何不合格TS57之紙品, 不理會厚度, 均要於浸水五分鐘後進行麥當勞TS37 咬/撕測試 (不包括預前環境處理). 若廠方提供的貼紙不合格TS57, 該貼紙須進行TS60之剷貼紙測試.Specification and Comments:See Summary of Method section.Summary of Method:The specimens will be submerged into water for 5 min. and either their wettability or their wet tensile strength will be tested, depending on the thickness of the products.Procedure: 程序1.0Coated products with thickness less than or equal to 0.3 mm (0.012 in.).已過塗層紙品厚度少於或等於0.3毫米(0.012吋)1.1Draw 12 random samples from the product lot.於生產批內 隨機抽12樣辦. 1.2Cut the samples to the dimension of 25.4 mm2 (1.0 in.2). If the sample is smaller than the required dimension, use the specimen as received with no side(s) longer than 25.4 mm (1.0 in.).樣辦剪為尺寸25.4平方毫米(1.0平方吋). 若樣辦少過所需尺寸, 使用收辦狀態下之樣辦, 無一邊是長過25.4毫米(1.0吋).1.3Weigh the dry test specimens to an accuracy of +/- 0.001 g (M1).量度乾樣辦重量至準確度 +/-0.001克 (M1).1.4Wholly immerse the individual specimens in 12.7 mm (0.5 in.) deep tap water at room temperature for 5 min. 於室溫下把每個樣辦完全浸入 12.7毫米(0.5吋)深的水喉水五分鐘.1.5Withdraw the specimens; lay them flat on the pad of blotting paper to remove excess water.取出樣辦, 平放在吸水紙上吸去多餘水份.1.6Weigh the wetted specimens to an accuracy of +/- 0.001 g (M2)量度濕樣辦重量至準確度 +/-0.001克 (M2).1.7Repeat steps 1.3 to 1.6 for each of the other 11 test specimens.其他樣辦 重複程序1.3 至Calculate the total percent water absorption to one decimal point for each test specimen, using the formula:Where: M1 = the mass, in grams, of the test specimens before immersionM2 = the mass, in grams, of the test specimens after immersion使用下列公式計算每個樣辦的總吸水量至1個小數位 :M1 = 樣辦浸水前之重量, 克M2 = 樣辦浸水後之重量, 克1.9Report the total percent water absorption as the average of the 12 results obtained from the 12 test specimens. The average total water absorption is rounded to a whole number.記錄12個樣辦測試結果的平均值 為總吸水百份比. 平均總吸水百份比四捨五入成整數.2.0Coated or uncoated products with thickness greater than 0.3 mm (0.012 in.).已過塗層或未過塗層紙品厚度大過0.3毫米(0.012吋)2.1Draw 12 random samples from the product lot.於生產批內 隨機抽12樣辦.2.2Cut two specimens, from the same sample if possible, in each principal direction of the sample. The dimension of the specimen shall be 19.1 mm to 25.4 mm (0.75 in. to 1.0 in.) wide and long enough to be clamped in the jaws, which are at least 25.4 mm (1.0 in.) apart.若可以, 從同一樣辦中的兩個不同方向剪出兩個測試樣辦, 尺寸為19.1毫米-25.4毫米(0.75吋-1.0吋)寬及長足夠可以兩邊致少距離25.4毫米(1.0吋)的位置用拉力鉗夾住. 2.3Make two even cuts at the middle of the specimen so that there are 12.7 mm (0.5 in.) of the specimen still connected (See Figure 1 below.).(M2 M1) / M1 x 100%與測試樣辦中間位置的兩邊各剪一刀, 令測試樣辦中間位置仍保留12.7毫米(0.5吋)是連接著的. (見圖一)(M2 M1) / M1 x 100%2.4Wholly immerse the individual specimens in tap water of 12.7 mm (0.5 in.) deep at room temperature for 5 min. 於室溫下把每個樣辦完全浸入 12.7毫米(0.5吋)深的水喉水五分鐘.2.5Withdraw the specimen; lay it flat and straight on a pad of blotting paper to remove excess water.取出樣辦, 平放在吸水紙上吸去多餘水份.2.6Clamp both ends of the specimen using two suitable clamps (with jaws wide and flat) and gradually load the specimen at a speed so that the time required to break the specimen is between 2 and 5 sec. To prevent jaw-tearing type breaks, the specimen has to be properly aligned with no twist in the clamps. Reject readings from individual tests if the specimen breaks at the edge of the clamps and change the type of clamps for the next test if necessary.使用適當鉗子(有平闊盤子的鉗子)鉗好測試樣辦的兩端, 逐漸上磅令測試樣辦於2-5秒內斷開. 為免鉗子盤邊的樣辦斷裂模式, 測試時應 儘量保持 測試樣辦與鉗子盤邊 平衡並不出現扭曲狀態. 若出現鉗子盤邊的樣辦斷裂模式, 該測試結果將不為正式結果, 重新測試另一樣辦及轉換另一種適合的鉗子, 如需要. Pass/Fail Criteria: 合格 / 不合格 要求 :For Procedure 1.0, thickness less than or equal to 0.3 mm (0.012 in.) - The average percentage of total water absorption should be equal or greater than 40%.程序1.0, 厚度少於或等於0.3毫米(0.012吋) 平均總吸水百份比須少於或等於4
