RAL is actually a colour matching system used in Europe that 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 utilized for varnish and powder coating but nowadays there are reference panels for plastics too. Approved RAL items are provided with a hologram as of early 2013 to make unauthorised versions difficult to produce. Imitations may show different hue and colour when observed under various light sources.
RAL Colour Charts are perfect for use within reference to choose the right 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 and for use when discussing power coating colours over the telephone. However, they are certainly not perfect for use within the workshop, especially if they are pinned for the wall. Here is where RAL Colour Swabs and Control Cards are available in.
A RAL Shade Swab is a fan of colour coated plastic with each fan detailing another RAL Tone & Colour. This fan is perfect for utilization in 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 offer a more accurate representation in the intended finished powder coating in my opinion applied to the metal component. Most Swabs have several hundred colours to them offering an entire range of colours, shades and tones available as powder coated finishes, and the RAL Swab will assist you to determine the preffered selection of powder coated finish.
However, the limitations from the RAL Shade & Colour Swabs are nearly as tight as the ones from the RAL Tone Charts pinned to the office wall. The small Swab tabs that are generally only 100mm long and 40mm wide do not offer an exact colour match, only a close representation. Here is where a RAL Colour Control Card comes into play.
The Colour Control Card is really a large specially prepared colour coated card prepared through the paint manufacturer. powder coating Colour Cards offer a perfect match up 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 as a result of 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 actually a cheaper fan type and also the K5 which includes more fan fingers each of which is committed to just one RAL tone, shade or colour. Ral Colour Charts are accessible for 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 beneath the name of “RAL 840”. Prior to that date manufacturers and customers were required to exchange samples to illustrate a tint, whereas from then on they would count on numbers.
In 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 absolutely was revised again in 1961 and changed to “RAL 840-HR”, which includes 210 colours and is also in use to this day. In 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, restricted to 193 colours. A primary criterion for colours inside the RAL Classic collection is to be of “paramount interest”. Therefore, the majority of the colours in it are used on warning and traffic signs or are focused on government departments and public services (as an example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
