Overview
SIST EN ISO 6553:2017 - Automatic steam traps - Marking (ISO 6553:2016) is an international standard that specifies essential and optional marking requirements for automatic steam traps. Published jointly by CEN and ISO, this standard ensures the clear identification of key characteristics and manufacturer details on automatic steam traps, which are widely used to efficiently discharge condensate and non-condensable gases in steam systems. The standardized marking supports operational safety, traceability, and compliance within industrial and commercial steam applications.
Key Topics
SIST EN ISO 6553:2017 covers the following principal topics regarding the marking of automatic steam traps:
General Requirements:
- Markings must be applied either on the body of the steam trap or on securely fixed plates that are integral to the body.
- Markings must be visible and not obstructed by the installation elements.
Mandatory Markings:
The following information shall be permanently marked:- Manufacturer’s name or trademark
- Maximum allowable pressure (in bar or MPa)
- Maximum allowable temperature (in °C)
- Flow direction (indicated by an arrow)
- Shell material designation
- Nominal size (DN or NPS) and nominal pressure (PN or Class designation)
- For steam traps without a defined nominal pressure or class, the maximum allowable pressure and temperature are mandatory.
Optional Markings:
- Maximum operating or differential pressure (as appropriate)
- Maximum test pressure
Additional Markings:
- Manufacturers may add other markings such as catalogue item numbers or duplicate mandatory/optional information in multiple locations, provided there is no risk of confusion.
Applications
Standardized marking of automatic steam traps as required by SIST EN ISO 6553:2017 is essential in a range of applications:
Industrial Steam Systems:
Facilitates safe operation and quick identification of steam trap specifications throughout power plants, refineries, chemical plants, and food processing facilities.HVAC and Building Services:
Ensures compliance and performance verification for steam traps used in commercial heating systems.Maintenance and Inspection:
Markings enable maintenance teams to easily verify equipment ratings, trace material specifications, and confirm replacements without ambiguity.Procurement and Supply Chain:
Standardized identification assists in sourcing and ensures components fulfill contract or system requirements globally.Regulatory and Quality Assurance:
Supports inspections by regulatory bodies and third-party auditors aiming to confirm adherence to international best practices and safety requirements.
Related Standards
When working with automatic steam traps and their marking, it is useful to be aware of related international standards:
ISO 5209 - General purpose industrial valves - Marking
Provides general marking requirements for industrial valves, referenced within SIST EN ISO 6553:2017.ISO 6552 - Automatic steam traps - Definition of technical terms
Offers standardized terminology and definitions for automatic steam traps’ technical aspects.EN 19 - Industrial valves - Marking of metallic valves
Specifies marking requirements for metallic valves and is aligned with the marking provisions in this standard.
By adhering to SIST EN ISO 6553:2017, manufacturers, suppliers, and operators can ensure effective communication of essential steam trap specifications, promote interoperability, and uphold a consistent level of safety and quality in steam trap applications worldwide.
