EN: (Determination of resistance of fuel oil) 安全鞋、勞保鞋、工作鞋耐油性的判斷：
1. General method 一般方法
1.1 Test liquid 測(cè)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(cè)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(gè)試片同時(shí)測(cè)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(duì)於多層大底，如果很難從結(jié)合緊密的大底上取得4mm厚的試片，可以從包括發(fā)泡層在內(nèi)的大底取樣。
1.3 Test procedure 安全鞋、勞保鞋、工作鞋耐油測(cè)試步驟
Follow the general procedure desribed in 8.2 of ISO 1817: 1985.
一般的測(cè)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(huán)境下，將試片浸入測(cè)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(jì)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(guò)10A，用ISO 868 : 1985的方法進(jìn)行判定；按2.2的方法準(zhǔn)備試片， 用2.3的方法進(jìn)行測(cè)試。
2. Method for outsole materials which shrink or become hardened 外底材料收縮或變硬的測(cè)試方法
2.1 Test liquid 測(cè)試溶液
As described in 1.1. 見(jiàn)條文1.1。
2.2 Preparation of test piece測(cè)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(zhǎng)的試片，打磨至隻有3 mm ± 0,2 mm厚為止。
2.3 Test procedure測(cè)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(huán)境下，將試片浸入測(cè)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(duì)試片進(jìn)行150，000次測(cè)試後，確定試片的增長(zhǎng)量。
