Oxygen Bomb Aging Test Chamber Product Overview
The oxygen bomb aging test chamber is designed for accelerated ageing of cable insulation, cable sheathing, vulcanized rubber, elastomeric appliance components and other applicable polymer specimens under controlled temperature and gas pressure. It supports both pressurized oxygen and compressed-air test modes, allowing laboratories to perform different material-ageing procedures with one system.
Unlike a conventional hot-air ageing oven, the oxygen bomb aging test chamber creates a sealed and pressurized oxidative environment around prepared material specimens. This controlled exposure helps laboratories evaluate how insulation, sheath and rubber compounds respond to accelerated thermal and oxidative ageing before their mechanical properties are compared with unaged reference specimens.
The equipment is intended for material specimens rather than complete household appliances. For appliance safety laboratories, the oxygen bomb aging test chamber can support relevant rubber and insulating-material assessments associated with IEC 60335-1. For cable laboratories, its air bomb and oxygen bomb modes support pressure-ageing work referenced by IEC 60811-412 and applicable Indian cable standards.

Oxygen Bomb and Air Bomb Test Modes
The oxygen bomb aging test chamber supports two pressure-ageing modes, but oxygen bomb ageing and air bomb ageing are separate methods and should not be treated as interchangeable.
| Test Mode | Test Medium | Typical Application |
|---|---|---|
| Oxygen bomb ageing | Pressurized oxygen | Rubber, elastomeric components and cable materials where oxygen-pressure ageing is specified |
| Air bomb ageing | Pressurized compressed air | Cable insulation and sheathing compounds covered by IEC 60811-412 or related specifications |
Test Principle and Workflow
Prepared specimens are suspended inside the steel vessel of the oxygen bomb aging test chamber without touching each other or the chamber wall. After the vessel is closed and locked, oxygen or compressed air is introduced according to the selected method.
The operator sets the specified pressure, temperature and ageing time. After exposure, pressure is released gradually, and the conditioned specimens are transferred to the required post-ageing evaluation equipment.
01 · Prepare
Prepare and condition specimens according to the applicable procedure.
02 · Load
Mount specimens on the internal holder with the required spacing.
03 · Pressurize
Close the vessel and introduce oxygen or compressed air.
04 · Age
Maintain the specified pressure and temperature for the required duration.
05 · Release
Reduce pressure gradually after the ageing period.
06 · Evaluate
Condition and compare aged specimens with unaged references.
Representative Oxygen Bomb Test Conditions
The original product information lists the following representative conditions for an IEC 60335-1 application of the oxygen bomb aging test chamber.
Design and Operation Features
The oxygen bomb aging test chamber combines dual-medium operation, controlled pressure ageing and laboratory safety functions in a compact material-testing system.
Dual-Medium Capability
The oxygen bomb aging test chamber supports both oxygen and compressed-air ageing for laboratories working with different material standards.
Controlled Pressure and Temperature
Pressure and temperature can be adjusted within the equipment’s rated capability to match the selected test procedure.
Steel Pressure Vessel
A steel vessel contains the heated and pressurized test environment. Detailed vessel specifications can be confirmed for the selected configuration.
Digital Temperature Control
The digital controller supports temperature setting and monitoring with a confirmed temperature deviation of ±0.5°C.
Integrated Safety Functions
Vessel locking, overpressure protection, temperature protection and controlled pressure release support laboratory operation.
Flexible Specimen Arrangement
The specimen holder and loading capacity can be matched to sample dimensions, spacing and the applicable test method.
Typical Test Objects
The oxygen bomb aging test chamber is intended for prepared specimens of applicable cable, rubber and polymer materials.
Typical Laboratory Applications
The oxygen bomb aging test chamber is suitable for organizations that need controlled pressure-ageing capability for material development, conformity preparation and routine quality control.
Cable Manufacturers
Qualification testing, formulation comparison, incoming-material inspection and routine control of insulation and sheath compounds.
Appliance Safety Laboratories
The IEC 60335-1 oxygen bomb aging tester supports applicable assessments of rubber parts, power-cord materials and internal wiring insulation.
Material Manufacturers
Comparison of rubber, elastomeric and polymer formulations through mechanical-property evaluation before and after ageing.
Testing and Certification Bodies
Standard-based pressure-ageing projects requiring controlled temperature, pressure and documented laboratory procedures.
Post-Ageing Evaluation
The oxygen bomb aging test chamber performs the controlled exposure stage. It does not independently determine whether a specimen passes or fails. After ageing, laboratories normally condition the specimens and evaluate the properties required by the applicable specification.
Configuration and Selection Notes
Correct selection of an oxygen bomb aging test chamber depends on the required gas medium, specimen arrangement, operating conditions and documentation scope.
Test Medium
Confirm whether the laboratory requires oxygen bomb ageing, air bomb ageing or both methods.
Working Pressure
The maximum working pressure is 2.5 MPa; the actual test pressure must follow the selected standard.
Specimen Holder
Holder design and loading quantity depend on specimen dimensions and required spacing.
Gas Connections
KINGPO can provide the agreed oxygen and compressed-air connection arrangement for the project.
Documentation
Pressure and temperature documentation should be matched to the laboratory’s project and quality-system requirements.
Related Equipment
A complete setup may also require tensile testing, sample preparation, thickness measurement and conditioning equipment.
Installation and Safety Considerations
Because the oxygen bomb aging test chamber operates with heated pressurized gas, installation and operation should be managed by trained laboratory personnel under controlled conditions.
- Install the equipment on a stable surface in a dry and adequately ventilated laboratory.
- Check electrical grounding, gas connections and pressure regulators before operation.
- Prevent oil, grease and incompatible contaminants from entering the oxygen gas path.
- Do not open the vessel while it remains pressurized.
- Release pressure gradually after the ageing period.
- Follow local requirements for pressure vessels, oxygen service, ventilation and occupational safety.
