General Information
Overview
ISO 3948:1977 is an international standard that defines the pressure ranges for compressed-air systems used in shipbuilding, specifically for inland vessels. This standard applies to the selection and design of equipment, machinery, and pipeline elements in compressed-air systems that support various essential functions on inland navigation vessels.
The objective of ISO 3948 is to unify the operating pressure ranges for starting-air and compressed-air systems to ensure safety, reliability, and compatibility across components. It addresses pressure specifications critical for equipment such as air receivers, compressors, pneumatic control systems, and safety devices.
Key Topics
Starting-Air Pressure Ranges
Defines the working and initial pressures suitable for starting-air systems used in main and auxiliary engines or diesel generators, facilitating the selection of compressors, fittings, and air receivers.- Pressure values range from 2,000 kPa up to 15,000 kPa in standardized intervals.
- Ensures the air receiver can supply sufficient compressed air to start a cold engine multiple times before recharging.
Compressed-Air System Pressure Ranges
Specifies pressure ranges essential for various vessel systems relying on compressed air, such as:- Blast signals and pneumatic tanks
- Windshield wipers
- Towing winch brakes and coupling locks
- Pneumatic dampers on exhaust-heat boilers
- Pneumatic control of main engines
- Ozonizer units and domestic air supply
- Blowing Kingston valve boxes, casting off towing hooks, and releasing anchors
Principal and Additional Pressure Series
The standard differentiates between principal pressure values for common applications and additional ones for exceptional cases, promoting flexible yet standardized system design.- Principal series covers common operational pressures (e.g., 50 kPa, 100 kPa, 150 kPa).
- Additional series offers alternative values for specific equipment requirements.
Definitions and Scope
Clarifies essential terms such as:- Starting-air pressure - operating pressure for which equipment is designed to function optimally.
- Initial pressure - maximum working pressure considered in system design.
Applications
ISO 3948:1977 is crucial for designers, engineers, and manufacturers involved in inland vessel shipbuilding and maintenance by providing:
Reliable Equipment Selection
Ensures correct pressure ratings are chosen for compressors, air receivers, pipelines, valves, and pneumatic devices, improving performance and lifespan.Safety and Compliance
Establishes pressure limits that prevent equipment overloading and failure, contributing to safer operation of compressed-air systems on board vessels.System Compatibility
Standardization of pressure ranges promotes interoperability of components and reduces modification needs during vessel retrofits or repairs.Wide Equipment Coverage
Applies to multiple pneumatic control systems critical for engine operation, safety mechanisms, and crew comfort-making it integral to comprehensive vessel system design.
