Unfortunately, it is also impossible to avoid the ravages of time taking their toll on high-quality products and goods that have been designed to offer a long service life. The good news: expert maintenance work, regular servicing and professional care can significantly prolong the service lives of many products and also help them function reliably and retain their value over the long term. The RAL Quality Mark for Engine Repairs also stands for high-quality services in the sense of durability just like the RAL Quality Mark for the Maintenance of Fire Protection Systems and the RAL Quality Mark for the Cleaning and Protection of Façades and Historical Monuments. 

Reliable protection for historical monuments
The preservation of historical monuments is essential in order to maintain historical substances and architectural heritage for future generations. The professional cleaning of historical monuments and façades is an integral part of a well thought-out preservation concept. Mistakes and oversights can prove very expensive in this area. This could simply be selecting the wrong cleaning agent or using an unsuitable process that causes irreparable damage. The RAL Quality Mark for the Cleaning and Protection of Façades and Historical Monuments guarantees specialist cleaning services provided by regularly trained personnel and the exclusive use of pH-neutral cleaning agents and preservatives. Before and after the cleaning process, it is necessary to take reference measurements on sample areas to avoid any risks.

A faulty engine does not mean the end of the line
Alongside the transmission, the engine is the most expensive part of a vehicle. A faulty engine often means the end of the line for a vehicle. Yet it is entirely possible that the engine can be successfully repaired. However, it is difficult to spot unscrupulous repair companies and the steps involved in a general overhaul of an engine are not uniformly regulated. The RAL Quality Mark for Engine Repairs covers all combustion engines – from passenger car and truck engines through to marine engines – and provides good guidance for reliable repair work. It defines the detailed technical and staffing requirements for completing a successful general overhaul, repair or service. Companies who offer engine repair services labelled with the RAL Quality Mark work according to a fixed catalogue of individual services in which all of the steps are defined. This includes testing the condition of all components and, if necessary, repairing or replacing them.

Safety thanks to professional servicing
Regular servicing – such as in the area of fire protection – ensures safety. The RAL Quality Mark for the Maintenance of Fire Protection Systems – which was recently updated to take account of the latest developments – helps prevent the worst outcome in the event of a fire. For example, fire extinguishers must be professionally serviced every two years to ensure that they work reliably. Regularly inspected hold-open systems help to slow down the spread of smoke and fire. Personnel carrying our maintenance services that carry the RAL Quality Mark have to regularly participate in further training courses so that they always possess the latest expertise. The RAL Quality Mark for the Maintenance of Fire Protection Systems places a focus on reliable fire protection and the safety of people and properties, as well as on the durability of the equipment and systems.
