دستکش عایق برق ضد برش رجلتکس کلاس سه 30000 ولت

FLEX & GRIP® : The range of composite insulating gloves for working in full safety without leather protectors.

Manufactured according to the standards (EN-60903 & IEC-60903), the range has been created in taking into consideration the expectations from users. Then, the range FLEX & GRIP® is innovative in term of products, seeing that we propose :

• One type of « low voltage» composite gloves for any live working under 1 000 volts : the FLEX & GRIP® BT/LV,
• the class 1, tested to 10 000 volts for a maximum use voltage of 7500 volts
• classes 2, 3 and 4 (respectively for the max. uses voltages of 17 000, 26 500 and 36000 volts), which the specification fully answer by the standards requirements (EN 60903:2003 et IEC 60903:2002)

FLEX & GRIP® is also innovative by the selection of raw materials which grant a good suppleness, in spite of the thickness required to protect entirely against the mechanical hazards. ln the same way, the chemical formula of the outside layer gives an exceptional « grip », even in wet conditions.

To reduce the effects of sweating, each pair of FLEX & GRIP® is sold with a pairs of cotton liner. Separated, the cotton liners may be replaced, thus limiting bacteriological problems associated with residual humidity caused by sweating.

Summary Table

*Obtaining a category authorises an additional thickness of O.6mm
Signification of category letters :
R = Resistance to acid, ozone and oil – C = Resistance to very low temperature.

Electrical requirements (routine tests and sampling tests in alternating current)

1. ln the choice of class, it is important to define the network nominal voltage which must not exceed the maximum operating voltage. For multiphase networks, the network nominal voltage is the voltage between phases.
2. The proof test voltage is the one applied to gloves during the individual routine tests.
3. The withstand voltage is the one applied during the validation tests after the gloves have been conditioned for 16 hours in water and after a 3-minutes test at the proof voltage.

Mechanical requirements (sampling test)

• Average tensile strength : ≥ 16 MPa
• Average elongation at break : ≥ 600%
• Tension set : ≤ 15 %

The additional tests and performance levels to be obtained are as follows :

• Resistance to abrasion : ≤ 0.05 mg/t (no equivalence level according to the EN 388 standard)
• Resistance to cutting : > 2.5 (equivalence level 2 according to EN 388)
• Tearing resistance : > 25 N (equivalence level 2 according to EN 388)
• Puncture resistance : > 60 N (equivalence level 2 according to EN 388)

Ageing requirements (sampling test))

Conditioning of the gloves in an air oven at 70 ± 2 °C for 168 hours :

• The elongation at break values must be at least equal ta 80% of those of non conditioned gloves.
• The tension set must not exceed 15%.
• The gloves must pass the proof test voltage.

Thermal requirements (sampling test)

1. Resistance to low temperature :conditioning of gloves for 1 hour at -25 ± 3°C. The tests are satisfactory if no tearing, breaking or cracking after folding is visible on the cuff and if the gloves pass the proof test voltage.
2. Flame retardancy test :Application of a flame for 10 seconds at a finger tip. The test is satisfactory if, after 55 seconds, the flame has not reached the marker located 55mm away at the other end.

Special properties (sampling test)

1. Resistance to acid :conditioning of gloves by immersion for 8 hours at 23 ± 2 °C in a sulphuric acid solution at 32° Baume.• The tensile strength and elongation at break values must be at least equal to 75% of those of non-conditioned gloves.

   • The gloves must pass the proof test voltage.

2. Resistance to oil :conditioning by immersion in oil (Iiquid 102) for 24 hr at 70 ± 2 °C• The tensile strength and elongation at break values must be at least equal to 50% of those of non-conditioned gloves.

   • The gloves must pass the proof test voltage.

3. Resistance to ozone :conditioning of gloves in a chamber for 3 hours at 40 ± 2 °C and in a 1 mg/m3 ozone concentration• The gloves must not present any cracking

   • The gloves must pass the proof test voltage.

4. Resistance to very low temperatures :conditioning of gloves for 24 hours at -40 ± 3°CThe tests are satisfactory if no tearing, breaking or cracking after folding is visible on the cuff and if the gloves pass the proof test voltage.

Packaging

Each pair of gloves is packaged in a different coloured opaque sachet depending on its class of protection.

The following information is given on the packaging : c1ass, size, categories, type of cuff, length, test date, manufacture batch number and validation batch number.
