Safe Gas Rwanda and its line of composite cylinders are certified in accordance with the Rwanda Beureau of Standards and the Energy Regulatory Commision. This implies that filled products may be transported and used in all Rwanda 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.
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.
Composite LPG cylinders are 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.
The EU type approval (TPED) stipulates a 10-year retesting interval while other countries and/ or local approvals stipulate other retesting intervals. The retesting procedure must be approved by the competent authorities in each country.
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.
The Cylinders are 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. 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.
