EN 388: 2016

Protective gloves against mechanical risks

机械风险防护手套

This is the most common European Standard for testing gloves to be used in general industrial applications. It is also referred to in many of the specialist glove standards, for activities such as welding and handling of chemicals. EN 388 was first published in 1994 and subsequently revised in 2003 and 2016. It includes four main physical tests to assess the resistance of the gloves palm area to mild abrasion, cutting, tearing and puncture. The performance of the glove is graded in accordance with four or   five performance levels. The end user is then able to select a glove with a performance level profile that suits a particular work activity. So forexample, a glove could be performance level 4 for abrasion but level 1 for tearing (in European standards the higher the number, the greater the protection).

这是测试一般工业用手套的最常见的欧洲标准。许多专业手套（例如用于焊接和化学品处理）标准中也有提到。EN 388于1994年首次发布，随后在2003年和2016年进行了修订。它包括四项主要的物理性测试，用于评估手套手掌区域对轻度磨损，切割，撕裂和穿刺的抵抗力。手套的性能按照四到五个等级进行划分。然后，最终用户能够根据具体工作活动来选择相应综合性能的手套。例如，手套可以具有4级耐磨性能，而撕裂性能为1级（在欧洲标准中，数字越高，保护功能越强）。

Abrasion磨耗

Samples are cut from the palm of a glove and rubbed against a 180 grit abrasive paper using a “Martindale” type abrasion machine. The number of cycles for the samples to hole is measured. Four performance levels are defined in EN 388 ranging from level 1 = holing > 100 cycles to Level 4 = holing > 8000 cycles.

从手套的手掌区域取样，置于“Martindale”摩擦测试仪上用180号砂纸上摩擦。测量样品上出现破孔时的摩擦次数。EN 388中定义了四个性能等级，范围从1级= 破孔> 100个循环到4级= 破孔> 8000个循环。

Blade Cut刀片切割

Samples are taken from the palm of a glove and the number of cycles to cut through the full thickness of the test sample by a circular rotating blade is recorded. Blade sharpness will vary and is assessed by using the cut test machine to cut through a standard reference fabric. The cut resistance of the glove is based on a relative index that compares the number of cycles to cut through the glove when compared with the standard fabric. Five performance levels are defined in EN 388 ranging from level 1 = Cut index > 1.2 to Level 5 = Cut index > 20.

从手套的手掌区域取样，用圆形旋转刀片切割测试样品，记录样品被割穿时刀片的循环次数。刀片锋利度会有所不同，评估方法是将其装在切割试验机上切割标准参考织物。手套的耐切割性是基于相对指数的，即比较割穿手套和割穿标准织物的刀片循环次数。EN 388中定义了五个性能等级，范围从1级 = 切割指数> 1.2到5级 = 切割指数> 20。

Tear撕裂

 “Trouser leg” type samples are taken from the palm of a glove and are torn apart using a standard tensile test machine. Four performance levels are defined in EN 388 ranging from level 1 = tear strength > 10N to Level 4 =tear strength > 75N.

 “裤型撕裂”样品取自手套的手掌区域并使用标准拉伸试验机来撕裂。EN 388中定义了四个性能等级，范围从1级= 撕裂强度> 10N到4级= 撕裂强度> 75N。

Puncture穿刺

Samples are taken from the palm of a glove and the force required to penetrate the sample with a defined stylus using a tensile test machine is measured. Four performance levels are defined in EN 388 ranging from level 1 = Puncture force > 20N to Level 4 = Puncture force >150N.

从手套的手掌区域取样，置于拉伸试验机上，用专门的触针穿刺，记录穿透样品所需的力。 EN 388中定义了四个性能等级，范围从1级= 穿刺力> 20N到4级= 穿刺力> 150N。

Impact Protection撞击防护

Other than the fingers, each area where impact protection is claimed shall be tested for impact attenuation by measuring the peak transmitted force. To meet the requirements this force must be below a defined value.

除了手指部位之外，每个声明的撞击防护区域都要通过测量峰值传递力来评估撞击衰减性能。该力必须低于规定值，才能达到要求。
