RAL is actually a colour matching system utilized in Europe which is created and administrated by the German RAL gGmbH (RAL non-profit LLC), that is a subsidiary of the German RAL Institute. In colloquial speech RAL refers to the RAL Classic system, mainly employed for varnish and powder coating but nowadays you can find reference panels for plastics as well. Approved RAL items are provided 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 ideal for utilization in reference to choose the right colour for painting using powder coat colours although other tools including RAL Colour Swabs and RAL Colour Control Cards are frequently more useful.
A RAL Colour Chart is perfect for hanging on the wall for general reference and for use when discussing power coating colours on the phone. However, they are not ideal for utilization in the workshop, especially when they are pinned for the wall. This is when RAL Colour Swabs and Control Cards are available in.
A RAL Shade Swab is keen on colour coated plastic with each fan detailing another RAL Tone & Colour. This fan is perfect for use in the task shop as well as off site and at a customers factory when discussing important powder coating decisions. The RAL Shade Swab can be put upon an item to give a far more accurate representation of the intended finished powder coating to me applied to the metal component. Most Swabs have several hundred colours to them offering a complete selection 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 of the RAL Shade & Colour Swabs are almost as tight as those of the RAL Tone Charts pinned towards the office wall. The little Swab tabs that are generally only 100mm long and 40mm wide tend not to provide an exact colour match, merely a close representation. This is when a RAL Colour Control Card comes into play.
The Color Control Card is actually a large specially prepared colour coated card prepared from the paint manufacturer. powder coating Colour Cards offer a ideal match up against the manufacturers paint and can be kept as reference for later colour matching exercises. RAL Coating Cards are suitable for 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 can be found in the K7 format which shows 5 colours per fan finger, and therefore is a cheaper fan type as well as the K5 that has more fan fingers all of which can be committed to a single RAL tone, shade or colour. Ral Colour Charts are for sale to purchase within 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 a selection of forty colours under the name of “RAL 840”. Before that date manufacturers and customers were required to exchange samples to describe a tint, whereas from that point on they might depend on numbers.
Inside the 1930s the numbers were changed uniformly to four digits as well as the collection was renamed to “RAL 840 R” (R for revised). With tints constantly put into the collection, it was revised again in 1961 and changed to “RAL 840-HR”, which includes 210 colours and is used for this day. Within the 1960s the colours were given 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 main criterion for colours in the RAL Classic collection is to be of “paramount interest”. Therefore, a lot of the colours within it are employed on warning and traffic signs or are committed to government agencies and public services (as an example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
