RAL is a colour matching system found 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 utilized for varnish and powder coating but nowadays you will 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 ideal for use within reference to pick a suitable colour for painting using powder coat colours although other tools such as RAL Colour Swabs and RAL Colour Control Cards tend to be more useful.
A RAL Colour Chart is great for hanging on the wall for general reference and for use when discussing power coating colours over the telephone. However, they are not ideal for utilization in the workshop, especially if they are pinned towards the wall. This is when RAL Colour Swabs and Control Cards are available in.
A RAL Shade Swab is a fan of colour coated plastic with every fan detailing an alternative RAL Tone & Colour. This fan is great for utilization in 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 upon an item to provide a much more accurate representation in the intended finished powder coating for me applied to the metal component. Most Swabs have several hundred colours upon them offering a total range of colours, shades and tones available as powder coated finishes, and also the RAL Swab will help you to determine the preffered collection of powder coated finish.
However, the limitations from the RAL Shade & Colour Swabs are almost as tight as those of the RAL Tone Charts pinned for the office wall. The little Swab tabs which are generally only 100mm long and 40mm wide tend not to present an exact colour match, just a close representation. This is when a RAL Colour Control Card is needed.
The Colour Control Card is a large specially prepared colour coated card prepared from 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 along with legal contract referencing. Whilst all colours might vary slightly due to changing powder coating environments and respective nacmlk regimes, the Ral Shade Card is considered 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 really a cheaper fan type as well as the K5 that has more fan fingers all of which is dedicated to just one RAL tone, shade or colour. Ral Colour Charts are for sale to purchase on 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 beneath 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 might rely on numbers.
Within 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 consists of 210 colours and is also used to this day. Inside the 1960s the colours received supplemental names 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, limited to 193 colours. A primary criterion for colours within the RAL Classic collection will be of “paramount interest”. Therefore, most of the colours in it are employed on warning and traffic signs or are committed to government departments and public services (as an example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
