The JOMY engineers are working with an extensive library of international, national and local standards and they will try to develop your stairs according to the applicable standards of your location.
Standard EN ISO 14122 requirements for stairs
The EN 14122 Safety of machinery — Permanent means of access to machinery and industrial plants is the most important standard requirement for our stairs. ISO 14122-3 is specifically dedicated to access stairs in an industrial environment and requires some safety criteria for steps and guardrails.
According to the standard EN ISO 14122, "Safety of machinery - Permanent means of access to machines and industrial plants," stairs provide safe access for angles between 20° and 45°.
ISO 14122-3 is specifically dedicated to access stairs in an industrial environment or for technical and maintenance access.
The following safety criteria are included in ISO14122-3 requirements:
- Steps must resist distributed load of 1.5 kN, distributed over an area of 100mm x 100mm (additional rules exist for steps wider than 1.2m).
- 600 < = g + 2h < 660
- The overlap of the steps must be 10mm and apply equally to landings and floors.
- The vertical height of the handrail on a stairway must be between 900mm and 1000mm above nosing on step of flight and minimum of 1100mm above walking level on landing.
- It must be equipped with 100mm toe-plate.
- Specific resistance and testing programs must be applied on guardrails.
