RAL is a colour matching system found 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 means the RAL Classic system, mainly employed for varnish and powder coating but nowadays you can find reference panels for plastics as well. Approved RAL goods are furnished with a hologram as of early 2013 to make unauthorised versions hard to produce. Imitations may show different hue and colour when observed under various light sources.
RAL Colour Charts are perfect for utilization in reference to choose a suitable colour for painting using powder coat colours although other tools like RAL Colour Swabs and RAL Colour Control Cards are frequently more useful.
A RAL Colour Chart is great for hanging on the wall for general reference and then for use when discussing power coating colours on the phone. However, they are certainly not ideal for use 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 every fan detailing another RAL Tone & Colour. This fan is great for use within the job shop in addition to off site and at a customers factory when discussing important powder coating decisions. The RAL Shade Swab can be put on an item to give a much more accurate representation of the intended finished powder coating to me placed on the metal component. Most Swabs have several hundred colours to them offering a total selection of colours, shades and tones available as powder coated finishes, as well as the RAL Swab will help to determine the preffered selection of powder coated finish.
However, the limitations from the RAL Shade & Colour Swabs are nearly as tight as those of the RAL Tone Charts pinned to the office wall. The tiny Swab tabs that are generally only 100mm long and 40mm wide usually do not provide an exact colour match, only a close representation. This is where a RAL Colour Control Card is necessary.
The Color Control Card is really a large specially prepared colour coated card prepared by the paint manufacturer. powder coating Colour Cards offer a ideal match up against the manufacturers paint and may 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 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 thus is a cheaper fan type and also the K5 that has more fan fingers all of that is focused on 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”. Just before that date manufacturers and customers were required to exchange samples to explain a tint, whereas from then on they could depend on numbers.
Inside 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 added to the collection, it absolutely was revised again in 1961 and changed to “RAL 840-HR”, which consists of 210 colours and is in use for this day. Within the 1960s the colours received supplemental names to prevent 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, limited to 193 colours. A main criterion for colours within the RAL Classic collection is to be of “paramount interest”. Therefore, most of the colours in it are employed on warning and traffic signs or are focused on government agencies and public services (as an example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
