IEC 60811 Cable Testing Equipment Oxygen Bomb / Air Bomb Aging Tester 200℃ 4MP

IEC60811-1-2 clause 8.3:

Ageing in an oxygen bomb

Test pieces as specified in Clause 9 of I EC Publication 811-1-1 shall be placed in the bomb at room temperature without touching each other. They shall not occupy more than one-tenth of the effective capacity of the bomb.
Compounds of substantially different compositions shall not be tested at the same time.
The bomb shall be filled with commercial oxygen of not less than 97% purity to a pressure of 2.1 ± 0.07 MPa.
The test pieces shall be kept in the bomb at the temperature and for the time specified for the material in the standard for the type of cable.
As soon as the ageing period is completed, the pressure shall be released gradually so as to reach atmospheric pressure in not less than 5 min, in order to avoid formation of porosity in the test pieces.                      Cable Testing Equipment
The test pieces shall then be removed from the bomb and left at ambient temperature, avoiding direct sunlight, for at least 16 h.
The tensile test shall then be carried out in accordance with Sub-clauses 9.1.6 and 9.1.7 of IEC Publication 811-1-1.

Standard: IEC60335-2-6 clause 22, IEC60335-2-9 clause 22,Clause 22.32 of IEC 60335-1 Household and similar electrical appliances – Safety – Part 1: General requirements, IEC 60811-1-1 sub clause 9.1 and IEC 60811-1-2 sub clause 8.3 and etc.

Application: It is used to process the aging test for the electric wire, the insulation layer and sheath of the rubber( plastic,artificial leather) as well as other high polymer materials under the action of required pressure and temperature in the medium of oxygen and compressed air.

Test sample: Wires, cables, rubber (plastic, leather) insulation layer and sheath, as well as other polymer materials.           Cable Testing Equipment

Feature: The device adopts inside and outside dual-chamber structure, the samples are suspended in an oxygen tube, filling with oxygen purity ≥ 97%, make the pressure up to 2.1 ± 0.07 MPa and maintain the temperature at 70 ° ± 1 ° C, then process aging test for 96 hours in this state.                                                   Cable Testing Equipment
