Whilst a high value is normally considered as better, a low value is required in case of possibleentanglement with moving machinery.3.2glove providing a specific protectionglove that is designed to provide an area of improved protection for the whole hand or part of it3.3glove seriessingle glove style or glove type with the same palm material up to the wrist line where the only variants are size,length, left/right hand and colour3.4armpart of the body between the wrist and the shoulder
EN 388:2003 (E)54 RequirementsThe protective gloves according to this standard shall first meet all the applicable requirements of EN 420.A protective glove against mechanical risks shall have a performance level of 1 or above for at least one of theproperties (abrasion, blade cut, tear and puncture) classified according to the minimum requirements for each levelshown in table 1.NOTEGloves meeting the requirements for resistance to puncture may not be suitable for protection against sharplypointed objects such as hypodermic needles.Table 1 — Levels of performanceTestLevel1Level2Level3Level4Level56.1 Abrasion resistance(number of cycles)10050020008000-6.2 Blade cut resistance (index)1,22,55,010,020,06.3 Tear resistance (N)10255075-6.4 Puncture resistance (N)2060100150-5 Sampling and conditioning5.1Unless otherwise stated all specimens shall be taken from the palm of different gloves for classificationpurposes.5.2If relevant, additional areas of the protective glove shall be tested, e. g. for specific protection.5.3Conditioning of samples is as follows: Temperature (23 ± 2) C; Relative Humidity (50 ± 5) %.The period of conditioning is 24 h. Tests shall preferably be performed in the above mentioned environment.5.4If the test is performed in a different environment, it shall be started within 5 min after removal from theconditioning.5.5If special applications require testing in a different environment, it is the responsibility of the manufacturer orhis authorized representative to arrange for additional tests and to present the results including a full description ofthe testing environment in the information supplied by the manufacturer (clause 8).6 Test methods6.1 Abrasion resistance6.1.1 PrincipleCircular specimens of material are abraded under known pressure with a cyclic planar motion in the form of aLissajous figure, which is the result of the simple harmonic motions at right angles to each other.The resistance to abrasion is measured by the number of cycles required for breakthrough to occur. Breakthrough isunderstood to mean when a hole is worn through the test specimen.
EN 388:2003 (E)66.1.2 AbradantThe abradant shall meet the following specifications:a) Backing: The backing shall be of a suitable quality paper with a minimum weight of 125 g/m² ± 5 %;b) Adhesive: The adhesive shall be water soluble, of good quality and suitable for purpose;c) Abrasive: The glass used shall be of good quality, suitable for purpose and shall meet the sieve analysisrequirements given in table 2.Table 2 — Sieve analysis for the abrasiveRequirementSieve aperturemAll to pass212No more than 25 % to be retained on180At least 50 % to be retained on125Not more than 5 % to pass106The finished glass paper shall have the following characteristics:1) The breaking strength shall not be less than: Machine direction: 392 N/50 mm; Cross direction: 215 N/50 mm;2) The weight of the glass paper shall be 300 g/m²
± 10 %.6.1.3 ApparatusAn abrasion testing machine of the type described in EN ISO 12947-1 as a Martindale Wear and Abrasion machine isrequired. It shall fulfil the following requirement:Pressure on specimen(9 ± 0,2) kPaNOTEMore detailed specifications relative to the apparatus can be found in EN ISO 12947-1. The model number 103 (fourplaces) is appropriate.6.1.4Test specimensFour test specimens shall be taken from four individual gloves of the same glove series.Where the test specimen is made of several unbonded layers, the test is performed on each layer, and theclassification is based on the sum of the number of cycles.6.1.5Test procedureSetting up the machine.A.
General
EN 388:2003 (E)7Check that the top plate and abrading tables are parallel. Insert a dial gauge through the spindle bearing and movethe top plate by turning the drive shaft by hand. The needle movement of the dial gauge shall be within ± 0,05 mmover the whole surface of an abrading table.If machines are being used in which the specimen holders are connected to the weights by spindles, assemble eachempty specimen holder and place each one in position on the appropriate abrading table and insert the spindles. Usea feeler gauge to check for any gap between the face of the specimen holder insert and the table. The gap shall notbe greater than 0,05 mm. Rock the spindle from side to side and re-check with the feeler gauge. To avoid damagingabrading tables and metal inserts, do not run the testing apparatus with metal inserts in contact with the uncoveredabrading table.B.
Mounting test specimensPlace the ring of the specimen holder in position on the mounting plate provided on the base of the testing apparatus.Secure without tension carefully and centrally the test specimen on the metal insert by means of double-sidedadhesive tape under a weight of 10 kg applied during 5 min. Good adhesion can be achieved through the use ofdouble-sided tape which prevents loosening of the test specimen and the inclusion of air bubbles.While ensuring that the ring containing the specimen and metal insert is held firmly in the mounting plate, start toscrew the top of the specimen holder on to the ring, taking care that the screw threads are not crossed. Having startedthe screwing down operation, use both hands to maintain a continuous downward pressure on the assembly againstthe mounting plate.This procedure will normally ensure that the specimen is securely retained in the holder in a wrinkle-free condition andthat it is ready for testing.NOTEAn example of appropriate double-sided adhesive tape is product ref. 465 from 3M. This information is given for theconvenience of users of this standard and does not constitute an endorsement by CEN/TC 162 of the product named. Equivalentproducts may be used if they can be shown to lead to the same results.C.
Mounting abradant1)Secure carefully the abradant 1)
by means of double-sided adhesive tape. Ensure the abradant is flat by placing theweight supplied with the testing machine for this purpose on its surface, and then position and tighten up the retainingframe evenly using diagonally opposite screws in sequence. Make sure that the abradant is held in place firmly andthat there are no tucks or ridges.D.
Mounting specimen holdersMount the test specimen holders on the top plate under a pressure of (9 ± 0,2) kPa and switch on the testing machine.Every time a specimen holder is taken from the machine to check the end point of the specimen for breakthrough,retighten the specimen holder before it is replaced on the machine.If it is necessary to interrupt the test for an appreciable length of time (e. g. overnight or at the weekend) remove thespecimens in their holders and store them face upwards. Protect the specimens by covering them with a clean card orpiece of fabric.E.
Method of assessmentEach test shall be performed with a new abradant. Begin the test and check the test specimens after 100 cycles. Ifthere is no breakthrough continue the test until reaching 500 cycles (performance level 2). If there is no breakthrough,
1) An example of suitable abradant is OAKEY Glass Quality Cabinet Paper Grade F2, Grit 100 – Self-adhesiveabradant is acceptable.This information is given for the convenience of users of this standard and does not constitute an endorsement by CEN/TC 162 ofthe product named. Equivalent products may be used if they can be shown to lead to the same results.
EN 388:2003 (E)8continue the test until the next performance level in table 1 is reached. Examine the test specimens at the requiredcycle number for each performance level.At each examination of a specimen at a specified performance level, both the test specimens and the abradant shallbe cleaned (e. g.) by cle
