What is PD CEN/TR 14473 about?
PD CEN/TR 14473 specifies information about monolithic porous materials used in individual acetylene cylinders and in acetylene cylinder bundles in Europe. PD CEN/TR 14473 does not claim to be exhaustive.
Acetylene storage in cylinders is important in the industrial gases industry due to its potential to break down explosively in the absence of air or oxygen. Therefore, storing acetylene in cylinders requires extra precautions to avoid explosive decomposition.
PD CEN/TR 14473 contains data and information about monolithic porous materials for acetylene cylinders.
This is accomplished by filling the cylinder with porous material capable of preventing acetylene decomposition.
Note: Where there is any conflict between PD CEN/TR 14473 and any applicable regulation, the regulation always takes precedence.
Who is PD CEN/TR 14473 for?
PD CEN/TR 14473 on transportable acetylene cylinders is relevant to:
- Industrial gases industry
- Any entity responsible for cutting and welding processes
- Acetylene gas cylinders manufacturers
- Chemical Engineers
Why should you use CEN/TR 14473?
Acetylene storage in cylinders is important in the industrial gases industry due to its potential to break down explosively in the absence of air or oxygen. Therefore, storing acetylene in cylinders requires extra precautions to avoid explosive decomposition.
PD CEN/TR 14473 guidelines for acetylene gas cylinders provide guidelines for the use of porous materials to ensure that acetylene gas cylinders can be safely stored and will not decompose.
Adhering to PD CEN/TR 14473 guidelines for porous material for acetylene gas cylinders can help you achieve stability, reliability, and compliance with European safety standards.
What’s changed since the last update?
PD CEN/TR 14473:2020 supersedes PD CEN/TR 14473:2014, which is withdrawn. PD CEN/TR 14473:2020 includes some technical changes with respect to PD CEN/TR 14473:2014. These include:
- Data of further porous materials has been added
- Clause 7 contains data for porous materials for acetylene cylinders approved to TPED evaluation of conformity at the time of manufacture
- Clause 8 contains data for porous materials for acetylene cylinders reassessed in accordance with TPED
- Clause 9 contains data for porous materials for individual acetylene cylinders that are type-approved based on national regulations
- The document has been aligned with the current principles and rules for the structure and drafting of CEN and CENELEC documents
