EN: (Determination of resistance of fuel oil) 安全鞋、劳保鞋、工作鞋耐油性的判斷：

1. General method 一般方法

1.1 Test liquid 測試溶液

2,2,4-trimethylpentane, general purpose reagent. 2,2,4三甲基戊烷為常用溶劑。

1.2 Preparation of test specimen 測試樣品的制備

Cut from the outsole two pieces of 16 mm ± 1 mm diameter and 4 mm ± 0,5 mm thickness and test both pieces at the same time.

從外底上割下兩片直徑為16 mm ± 1 mm，厚4 mm ± 0,5 mm的試片，且兩個試片同時測試。

For multilayered soles, if it is not possible to obtain a test piece of 4 mm thickness from the compact layer; cut a piece which includes part of the expanded layer.

對於多層大底，如果很難從結合緊密的大底上取得4mm厚的試片，可以從包括發泡層在內的大底取樣。

1.3 Test procedure 安全鞋、劳保鞋、工作鞋耐油測試步驟

Follow the general procedure desribed in 8.2 of ISO 1817: 1985.

一般的測試步驟為ISO 1817 : 1985的條文8.2。

Immerse the test piece in the test liquid ( 1.1 ) at a temperature of 20℃ ± 2 ℃ for a period of 22 h ± 0,25 h.

在溫度為20℃ ± 2 ℃的環境下，將試片浸入測試溶液中22 h ± 0,25 h。

Determine the increase in volume of the piece using the volumetric method.

用體積計確定試片的體積增加量。

If the test piece shrinks by more than 0,5% or increase in hardness by more than 10 Share A hardness units, determined using the method described in ISO 868: 1985, take a further test piece, as described in 2.2 and test as described in 2.3.

如果試片收縮大於0,5%或硬度增加超過10A，用ISO 868 : 1985的方法進行判定；按2.2的方法準備試片， 用2.3的方法進行測試。

2. Method for outsole materials which shrink or become hardened 外底材料收縮或變硬的測試方法

2.1 Test liquid 測試溶液

As described in 1.1. 見條文1.1。

2.2 Preparation of test piece測試樣品的制備

Take a test piece of nominal width 25 mm and nominal length 150 mm from the outsole of the footwear and reduce to an overall thickness of 3 mm ± 0,2 mm by roughing or scouring.

從鞋子的外底上取一25mm寬，150mm長的試片，打磨至隻有3 mm ± 0,2 mm厚為止。

2.3 Test procedure測試步驟

Immerse the test piece in the test liquid at a temperature of 20℃ ± 2 ℃ for a period of 22 h ± 0,25 h.

在溫度為20℃ ± 2 ℃的環境下，將試片浸入測試溶液中22 h ± 0,25 h。

Remove excess liquid with absorbent paper and determine the cut growth in the specimen after 150,000 cycles in accordance with the method described in annex C of ISO 4643: 1992.

用吸水紙吸去多余的溶液，用ISO 4643 : 1992的附件C中的方法對試片進行150，000次測試後，確定試片的增長量。

上属是安全鞋、劳保鞋、工作鞋耐油测试的判断。出自护足鞋业有限公司：www.aqshoes.com.
