RAL is actually a colour matching system utilized in Europe which is created and administrated by the German RAL gGmbH (RAL non-profit LLC), which is a subsidiary of the German RAL Institute. In colloquial speech RAL means the RAL Classic system, mainly employed for varnish and powder coating but nowadays you will find reference panels for plastics too. Approved RAL items are supplied with a hologram as of early 2013 to make unauthorised versions challenging to produce. Imitations may show different hue and colour when observed under various light sources.
RAL Colour Charts are best for utilization in reference to select a suitable colour for painting using powder coat colours although other tools such as RAL Colour Swabs and RAL Colour Control Cards are often more useful.
A RAL Colour Chart is ideal for hanging on the wall for general reference as well as for use when discussing power coating colours over the phone. However, they are not perfect for utilization in the workshop, especially if they are pinned towards the wall. This is where RAL Colour Swabs and Control Cards can be found in.
A RAL Shade Swab is keen on colour coated plastic with every fan detailing a different RAL Tone & Colour. This fan is perfect for use within the job shop in addition to off site as well as at a customers factory when discussing important powder coating decisions. The RAL Shade Swab can be put on an item to provide a much more accurate representation in the intended finished powder coating in my opinion put on the metal component. Most Swabs have several hundred colours to them offering a total range of colours, shades and tones available as powder coated finishes, as well as the RAL Swab will help you to determine the preffered selection of powder coated finish.
However, the limitations in the RAL Shade & Colour Swabs are almost as tight as the ones from the RAL Tone Charts pinned for the office wall. The tiny Swab tabs that are generally only 100mm long and 40mm wide do not offer an exact colour match, merely a close representation. Here is where a RAL Colour Control Card comes into play.
The Colour Control Card is actually a large specially prepared colour coated card prepared through the paint manufacturer. powder coating Colour Cards give you a ideal match against the manufacturers paint and will be kept as reference for later colour matching exercises. RAL Coating Cards are compatible with permanent colour references for technical documentation in addition to legal contract referencing. Whilst all colours might vary slightly due to changing powder coating environments and respective nacmlk regimes, the Ral Shade Card is regarded as the definitive reference for paint matching against RAL Powder Coating Colours.
Ral Colour Swabs are available in the K7 format which shows 5 colours per fan finger, and as such is actually a cheaper fan type and also the K5 which includes more fan fingers all of that is focused on a single RAL tone, shade or colour. Ral Colour Charts are available for purchase over the C&S Processing website at great rates.
In 1927 the German Reichs-Ausschuß für Lieferbedingungen und Gütesicherung (Imperial Commission for Delivery Terms and Quality Assurance) invented an accumulation of forty colours under the name of “RAL 840”. Just before that date manufacturers and customers needed to exchange samples to describe a tint, whereas from that point on they might count on numbers.
In the 1930s the numbers were changed uniformly to four digits and also the collection was renamed to “RAL 840 R” (R for revised). With tints constantly included in the collection, it absolutely was revised again in 1961 and changed to “RAL 840-HR”, which contains 210 colours and is also in use to this particular day. Within the 1960s the colours received supplemental names in order to avoid confusion in case of transposed digits.
As “RAL 840-HR” covered only matte paint the 1980s saw the invention of “RAL 841-GL” for glossy surfaces, confined to 193 colours. A primary criterion for colours inside the RAL Classic collection will be of “paramount interest”. Therefore, the majority of the colours within it are employed on warning and traffic signs or are committed to government agencies and public services (for example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
