Color standards used in powder coating When the colors used to specify powder in the UK there are a number of color standards to choose. The most commonly used are RAL and BS 4800. Other standards are used NCS, BS and sometimes Pantone 381C. Most powder manufacturers also produce a range of shades house and also many special order colors.
RAL
The RAL has been created by the "fa¼r Reichsausschuss Lieferbedingungen" or "Committee of the German Reich for Terms and Conditions of Sale.
In 1927, this organization has created the first RAL, RAL color 840 scale with 40 colors. The standard color RAL has now about 2000 shades.
A small subset of RAL colors (200 shades) RAL CLASSIC designated are the most commonly used in the powder in the United Kingdom. RAL CLASSIC Each is designated by a 4-digit numerical example, RAL 6005.
The RAL Classic is organized into color groups as follows:
Shade from 1 - beige / yellow / ivory
Shade from 2 - Orange
Shade from 3 - red / pink
Shade from 4 - purple / lilac / violet
Shade from 5 - blue
Shade from 6 - Green / Olive
Shade from 7 - gray
Shades from 8 - Brown
Shade from 9 - White / Black
Two of RAL RAL9006 and RAL9007 are different to the other classic colors RAL in that they are not really color standards (but special mention of the German railways). Therefore the appearance of these grades vary considerably between the powder factory. Â
Less commonly used are the RAL DESIGN that is designated by numbers such as 7 010 30 15 and RAL EFFECT designated by a 4-digit or three numbers plus the letter M (for metal) for example, 310-6 or 310-M.
SB 4800
'BS 4800:1989 - Calendar of paint colors for the building "
Each color in a standard 5-digit code composed of two numbers, one letter and two numbers above for example 10C31.
The same colors are also referred to BS5252: 1976
NCS Shades
NCS (Natural Color System) has its origin in Sweden in the 1920s. He is considered a "system of color vision and based on ideas taken from" Das nata¼rliche System der Farbempfindungen "published by the German physiologist Ewald Hering in 1874. NCS system is an attempt to create a color scheme visually descriptive.
Colors in the NCS are designated by a code of 8 alphanumeric characters defining the darkness, saturation and hue. The first 4 digits indicate the darkness and saturation, the second group of four digits refer to the color.
For example:
3050 Y80R means the darkness of 30%, saturation 50%, yellow 20% and 80% red.
BS381 C
The other British Standard color is "BS 381C: 1996 - Specification of colors for identification, coding, and" special needs.
These grades are designated by a 3 digit numeric code, for example 697. They are often specified for military and marine applications.
Pantone colors
The Pantone system is widely used in graphic design, printing, publishing, textile and plastics industries. It is sometimes indicated for the powder coating especially where a sign or piece of architecture is required to match a company logo or corporate colors.
The Pantone system was created in 1963 by Lawrence Herbert, to identify and match colors for the graphic arts community.
