ANSI / ASME A13.1 Has Changed! ANSI / ASME Size Chart
Pipes with Diameter (O.D.) 3/4” to 1-1/4” (19 to 32mm) Marker Length: 8” (200mm) Legend Height: 1/2” (13mm)
Latest Revision Revision ANSI / ASME A13.1-200 A13.1-2007 7 ANSI / ASME A13.1 is the most common pipe identification identification standard used in the United States, and until the latest revision dated 2007 the standard has been unchanged for nearly a half a century. The standard specifies the primary and secondary means of identifying identifying pipe content, as well as, the size, color and placement of the identification identification device.
Primary Identification: The legend (name of pipe content) and directional directional flow arrow remain the primary means of identifying identifying pipe content. content. The size and placement of the marker and arrow has not changed. changed. See ANSI / ASME size chart and installation installation guide for details. details.
Secondary Identification: Pipes with Diameter Diameter (O.D.) 1-1/2” to 2” (38 to 51mm) Marker Length: 8” (200mm) Legend Height: 3/4” (19mm)
The secondary secondary means of identification identification is the color code of the marker. marker. That portion of the standard has changed dramatically. In addition, the terminology of inherently hazardous or non hazardous hazardous has been removed from the standard. standard. The most obvious change, which will affect most of Brimar’s Brimar’s customers is the color code assignment assignment of two of the most widely used color combination combination of Yellow Yellow / Black and Green / White. The combination combination of Yellow Yellow / Black is now assigned assigned with flammable fluids, and Green / White shall now identify identify potable, cooling, boiler feed and other waters. These two changes changes mean that legends such as hot water, cold water and steam will now all use the color code of Green / White.
Pipes with Diameter Diameter (O.D.) 2-1/2” to 6” (64 to 150mm) Marker Length: 12” (300mm) Legend Height: 1-1/4” (32mm)
The other significant color changes include the addition of Brown / White for combustible combustible fluids and Orange / Black for toxic and corrosive corrosive fluids. The fact that the standard has identified specific colors for flammable fluids, combustible fluids and toxic or corrosive fluids means that Brimar and our customers must consult Material Safety Data Sheets before selecting a color. Further, if the pipe content contains multiple hazards (flammable (flammable and toxic) it must be determined which poses the greatest greatest risk. For example, if chilled or heating water systems contain a toxic treatment treatment the color combination combination should be Orange / Black. The new 2007 standard standard also identifies for the first time four additional additional user defined color combinations combinations and specifically specifically identifies all of the exact background background colors to be used. The exact colors are safety colors contained in the ANSI Z535.1-2007 Z535.1-2007 standard.

Pipes with Diameter Diameter (O.D.) Over 10” (Over 250mm) Marker Length: 32” (800mm) Legend Height: 3-1/2” (89mm)

ANSI / ASME A13.1 Has Changed! BRIMAR Compliance Guide
Compliance The new standard does not require the replacement of previously installed markers. The standard only applies to new installations. Brimar products comply with ANSI / ASME A13.1 standards and we are committed to a uniform standard of pipe identification. We recognize that it is not possible or realistic for everyone to adopt the new 2007 standard immediately and therefore Brimar will continue to offer markers that comply with the old and new standards. The Product Compliance Guide on the right shows the products that comply with the new standard. In addition, within the stock lists of each of these products, Brimar has identified which color combinations comply with the old and new standards.
Installation Guide
Brimar’s products comply with the recommendations stated in the ANSI / ASME A13.1 2007 Standard, including: marker length, legend size and marker colors. Below we have highlighted the most popular pipe markers we offer that are in compliance with the new standard.
EZ Pipe Markers Stick-On Labels comply with A13.1 2007 when used in conjuction with arrows
System #1 Pipe Markers 2nd Most Popular Pipe Markers Available in 8 different sizes Legends shall be installed close to valves Legends shall be installed near branches and whenever a pipe changes direction. Legends shall be installed before and after all wall, floor and ceiling penetrations. Legends shall be at frequent intervals on straight pipe runs. Brimar recommends 20 ft.
System #2 Pipe Markers Markers on a Roll / 2 Roll Sizes 8 x 1” & 14 x 2-1/4”
Legends shall be installed on pipes to achieve the best visibility.
System #3 Pipe Markers Markers on a Roll / 2 Roll Sizes 8” x 30’ & 12” x 30’
System #4 Pipe Markers High Temperature Resistant Markers Available in 6 different sizes
