RAL is 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 refers to the RAL Classic system, mainly utilized for varnish and powder coating but nowadays there are reference panels for plastics too. Approved RAL goods 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 perfect for use within reference to pick a suitable colour for painting using powder coat colours although other tools like 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 on the phone. However, they are certainly not suitable for use in the workshop, especially when they are pinned towards the wall. Here is where RAL Colour Swabs and Control Cards can be found in.
A RAL Shade Swab is a fan of colour coated plastic with each fan detailing a different RAL Tone & Colour. This fan is perfect for utilization in the job shop as well as off site and at a customers factory when discussing important powder coating decisions. The RAL Shade Swab may be placed with an item to provide a more accurate representation from the intended finished powder coating in my opinion applied to the metal component. Most Swabs have several hundred colours upon them offering an entire range of colours, shades and tones available as powder coated finishes, and the RAL Swab will help to determine the preffered choice of powder coated finish.
However, the limitations of the RAL Shade & Colour Swabs are almost as tight as the ones from the RAL Tone Charts pinned to the office wall. The small Swab tabs which can be generally only 100mm long and 40mm wide usually do not present 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 provide a perfect match from the manufacturers paint and will 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 purchased in the K7 format which shows 5 colours per fan finger, and as such is actually a cheaper fan type along with the K5 that has more fan fingers all of that is 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 an accumulation of forty colours beneath the name of “RAL 840”. Prior to that date manufacturers and customers were required to exchange samples to explain a tint, whereas from that point on they might rely 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 included in the collection, it had been revised again in 1961 and changed to “RAL 840-HR”, which contains 210 colours and is also in use for this day. Inside the 1960s the colours received supplemental names in order to avoid confusion in the event 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 within the RAL Classic collection is going to be of “paramount interest”. Therefore, the majority of the colours inside it are utilized on warning and traffic signs or are focused on government agencies and public services (for example: RAL 1004 – Swiss Postal Service, RAL 1021 – Austrian Postal Service, RAL 1032 – German Postal Service).
