Approvals and Certifications
Hexagon Ragasco AS and its line of composite LPG cylinders are certified in accordance with the Transportable Pressure Equipment Directive (TPED) modules B and C1. All cylinders are marked with Pi 0035 and -40C. This implies that filled products may be transported and used in all EC countries without further local approvals.
The original approval was based on the German/ADR requirements, granted in February 2000. TÜV München, which is accredited by ZLS as the approving authorities in Germany for this type of equipment, did the approval work. They also act as our notified body - the third party inspector approving the manufacturing line and the products.
For countries, that have not contracted ADR/RID, the local authorities must approve Hexagon Ragasco's composite LPG cylinders. By basing the application on the TPED-approval, experience is that local approval usually is a formality, and that for practical purposes has limited impact on time and cost during launching. TPED refers to ADR related to transportation of dangerous goods, thus a TPED product may be transported within the whole EU. Design, approval testing and production testing are based on the requirements of EN 12245 "Transportable Gas Cylinders - Fully Wrapped Composite Cylinders" and EN 14427 "Transportable Refillable Composite Cylinders for LPG - Design and Construction". Both standards are included in the ADR/RID (TPED) and equally valid. The Hexagon Ragasco line of composite LPG Cylinders is approved to both standards and type approval certificate according to both standards is available.
The Hexagon Ragasco line of Composite LPG cylinders is also in compliance with ISO 11119-3, which is very similar, except that it is approved by member countries from the whole world.
Both Pi-marked and locally approved valves are available for these cylinders, depending on the market/country. Valve design must be approved by Hexagon Ragasco and most approvals, including the TPED type approval, stipulate that the valve must be mounted and tightness tested by the cylinder manufacturer.
For filling and retesting, the CEN standardization organization has developed EN14763 and EN1440 as technical guidelines. These are approved by the CEN member countries, but they are not yet referred to in ADR as they were not ready in time for the last ADR revision.
In addition, Hexagon Ragasco has a product-specific document providing detailed instructions for filling and retesting its composite LPG cylinders. The EU type approval (TPED) stipulates a 10-year retesting interval while other countries and/ or local approvals stipulate other retesting intervals. Hexagon Ragasco is continuously performing tests to document the limited deterioration that normal use of the cylinders cause over time (no corrosion, no permanent deformation) and thus prove to the competent authorities that the retesting interval should be at least 10 years. The retesting procedure must be approved by the competent authorities in each country. Furthermore, Hexagon Ragasco is the only composite cylinder manufacturer to have achieved a 15-year interval for the first inspection of cylinders in Denmark, Finland, Norway and Sweden.
In the USA, the cylinders are approved in accordance with DOT-SP-12706, which is based on ISO11119-3.2, CFR49, FRP-1 and DOT specific requirements. The Authorized Testing Institute is the third-party approval organization for the manufacturing line and product.
In Canada, the cylinders are approved in accordance with TC-SU-5931, which is based on ISO11119-3.2 and BS 3.3.9, TC-3FCM, CAN/CSA B339 and further Transport Canada requirements. The Authorized Testing Institute is the third-party approval organization for the manufacturing line and product.
Hexagon Ragasco's line of composite LPG cylinders is also approved in a number of other countries such as Brazil, Iraq, Malaysia, Nigeria, Qatar, Saudi Arabia, South Africa, the United Arab Emirates, Venezuela, Vietnam and Uruguay. The local approvals are normally based on an acceptance of TPED and/ or EN12245 requirements. Hexagon Ragasco is dedicated to the task of achieving local approvals and providing support to the local competent authorities.
