EN388 mechanical hazards gloves Standard Introduction

EN388 is one of industrial gloves for protection of European standards, European Committee for Standardization (i.e. CEN) was adopted on July 2, 2003, the latest version.
EN388:2003 approval. The standard glove General labor is provided on the basis of the standard EN420 protective gloves for protection against mechanical hazards requirements, test methods, marking marking and instructions for use, suitable protective gloves in the mechanical hazards, can also be used to determine the impact cut gloves and antistatic properties.

 

The so-called "mechanical hazards" refers to the possible friction, cut, tear and puncture caused by the dangerous. Therefore, this four basic standards test performance is:

 

Wear resistance: repeated friction resistance of glove material cycles;

Cut resistance: Glove material anti laps cutting objects;

Tear resistance: the tear in the glove material pre-cut hole how many units of the force required;

Puncture resistance: the use of calibration spikes pierce gloves palm require much force.

 

EN388 standard performance tests above using mutually different methods, and the test results obtained by testing with different mechanical hazard symbol display for indicating that the control of the four basic tests gloves in each case the rating, and the results are recorded as performance ratings. The higher the rating, protective gloves provided, the better. Note that all tests were carried out under controlled laboratory conditions, these ratings provide information only, so you can compare the two gloves, to see which one is more appropriate use of gloves you need.

 

In general EN420 standard specifies the mechanical hazards gloves basic legend. The EN388 standard was refined this provision, see Figure:

 

The legend of "ABCD" symbol are four basic performance test performance rating, the higher the rating of each symbol (1-4 / 5) on behalf of the corresponding wear gloves, cut resistance, tear resistance crack resistance or puncture resistance, the better, so mechanical hazard protection can be achieved relatively best results.     

The standard level of performance:

 

 

Performance Level                              First   Second   third   fourth    fifth

A abrasion resistance (unit: circle)       100     500     2000     8000      -

B cut resistance (unit: times)              1.2      2.5      5.0       10.0      20.0

C tear resistance (unit: Newton)          10       25       50         75         -

D Puncture resistance (unit: Newton)   20       60       100       150       -

 

Understand classification rules, here a brief introduction to the test method for each performance.

Abrasion resistance test: the four round glove material samples (6.45 cm 2) at a known pressure (9 kPa) is friction, were 100,500,2000 and 8000 laps for each sample, performance Ratings are based on the minimum number of turns 4 times after the test may be. For example, A test material, if being damaged when friction occurs 500 times, then the A grade material is a wear resistance, and so on;

 

Cut resistance test: the two samples at 5 Newton uninterruptible forces test, according to the number of laps before the cut is determined to withstand rating; tear resistance test: The four test samples from four of the glove samples were cut on the palm, which will do two fingertips to test the direction of the cuff, the other two do palm width direction of the test, measured at a speed of 100mm / min sample tearing maximum force in Newtons; resistance puncture resistance test: uses the same four samples from four gloves palm cut, measured by the test at a speed of 100mm / min with a maximum sample nail piercing Newton force. In different mechanical hazards, the cutting injuries are most likely to have dire injury. And regardless of any industrial, cuts and lacerations occur mostly in the hands, the most serious hand injury occurs mainly meat processing and sheet metal processing industry, two industries

 

Thus, according to industry operational needs, we must be prepared to make the necessary precautionary measures to properly assess compliance with EN388 selection criteria mechanical hazard protective gloves, to reduce the likelihood and severity of injury, and select the corresponding level of performance and features, appropriate and fully protect the occupational safety and health workers.
