(Main)Industrial thermoprocessing equipment - Part 5: Particular safety requirements for salt bath thermoprocessing equipment
General Information
- Abstract
This part of EN 746 gives the specific hazards and safety requirements for the melting and use of molten salt that shall be provided by the manufacturer for Salt Bath Industrial Thermoprocessing Equipment, whether it is used as an independent unit or an integrated part of a plant. The limits of the equipment will include any transportation equipment which is located wholly or partially in the bath. This part of EN 746 does not cover the handling, storage, transport disposal, transfer or regeneration of the salts and processed material outside the limits of the equipment.

Overview
EN 746-5:2000 is a CEN standard that sets out the particular safety requirements for salt bath thermoprocessing equipment. It applies to equipment where molten salt is melted and used as part of industrial thermoprocessing operations, whether the salt bath unit is an independent machine or integrated into a plant. The standard defines the specific hazards manufacturers must address for safe operation within the physical limits of the equipment. It does not cover handling, storage, transport, disposal, transfer or regeneration of salts and processed materials outside the equipment boundaries.
Key Topics
EN 746-5 focuses on safety aspects specific to salt bath thermoprocessing and typically addresses the following subject areas (as provided in the scope and structure of the standard):
- Identification of hazards associated with molten salt use and immersion equipment.
- Manufacturer-provided safety measures that must be incorporated into design and documentation.
- Equipment limits - the standard covers components and transport mechanisms located wholly or partly within the salt bath.
- Operational safety boundaries - clarifies what remains outside the standard (external handling, storage and regeneration of salts).
- Safety documentation and instructions that manufacturers must supply for safe installation, operation and maintenance.
(Note: EN 746-5 defines the particular safety requirements; specific technical parameters such as temperatures, materials or alarm setpoints are detailed in the standard text and not repeated here.)
Applications
This standard is essential for organizations and professionals involved with salt bath furnaces and molten-salt thermoprocessing, including:
- Manufacturers and designers of salt bath industrial thermoprocessing equipment
- Plant engineers and integration teams specifying equipment safety features
- Safety and compliance officers responsible for machinery conformity with CEN standards
- Purchasing and procurement teams evaluating equipment for production lines
- Inspectors and maintenance personnel applying manufacturer instructions within equipment limits
EN 746-5 helps reduce risks inherent to molten salt processes and supports safe design, installation, and operation of salt bath systems in sectors such as metal heat treatment, surface engineering and process manufacturing.
Related Standards
- EN 746 series (Industrial thermoprocessing equipment) - other parts address general and specific safety requirements for different furnace types and installations.
- National and EU machinery safety regulations - used together with EN 746-5 to demonstrate conformity with legal safety obligations.
