B. Coordinate installation of identifying devices with location of access panels and doors.
C. Install identifying devices before installing acoustical ceilings and similar concealment.
PART 2 - PRODUCTS
2.1 PIPING IDENTIFICATION DEVICES
A. Manufactured Pipe Markers, General: Preprinted, color-coded, with lettering indicat- ing service, and showing direction of flow.
1. Colors: Comply with ASME A13.1, unless otherwise indicated.
2. Lettering: Use piping system terms indicated and abbreviate only as necessary for each application length.
3. Pipes with OD, Including Insulation, Less Than 6 Inches (150 mm): Full-band pipe markers extending 360 degrees around pipe at each location.
4. Pipes with OD, Including Insulation, 6 Inches (150 mm) and Larger: Either full- band or strip-type pipe markers at least three times letter height and of length re- quired for label.
5. Arrows: Integral with piping system service lettering to accommodate both di- rections; or as separate unit on each pipe marker to indicate direction of flow.
B. Self-Adhesive Pipe Markers: Plastic with pressure-sensitive, permanent-type, self- adhesive back.
C. Plastic Tape: Continuously printed, vinyl tape at least 3 mils (0.08 mm) thick with pressure-sensitive, permanent-type, self-adhesive back.
1. Width for Markers on Pipes with OD, Including Insulation, Less Than 6 Inches (150 mm): 3/4 inch (19 mm) minimum.
2. Width for Markers on Pipes with OD, Including Insulation, 6 Inches (150 mm) or Larger: 1-1/2 inches (38 mm) minimum.
2.2 VALVE TAGS
A. Valve Tags: Stamped or engraved with 1/4-inch (6.4-mm) letters for piping system ab- breviation and 1/2-inch (13-mm) numbers, with numbering scheme approved by Archi- tect. Provide 5/32-inch (4-mm) hole for fastener.
1. Material: 0.032-inch- (0.8-mm-) thick brass or aluminum.
2. Valve-Tag Fasteners: Brass wire-link or beaded chain .
2.3 WARNING TAGS
A. Warning Tags: Preprinted or partially preprinted, accident-prevention tags; of plasti- cized card stock with matte finish suitable for writing.
1. Size: 3 by 5-1/4 inches (75 by 133 mm) minimum .
2. Fasteners: Reinforced grommet and wire or string.
3. Nomenclature: Large-size primary caption such as DANGER, CAUTION, or DO NOT OPERATE.
4. Color: Yellow background with black lettering.
PART 3 - EXECUTION
3.1 APPLICATIONS, GENERAL
A. Products specified are for applications referenced in other Division 15 Sections. If more than single-type material, device, or label is specified for listed applications, se- lection is Installer's option.
3.2 PIPING IDENTIFICATION
A. Install manufactured pipe markers indicating service on each piping system. Install with flow indication arrows showing direction of flow.
1. Pipes with OD, Including Insulation, Less Than 6 Inches (150 mm): Self- adhesive pipe markers. Use color-coded, self-adhesive plastic tape, at least 3/4 inch (19 mm) wide, lapped at least 1-1/2 inches (38 mm) at both ends of pipe marker, and covering full circumference of pipe.
2. Pipes with OD, Including Insulation, 6 Inches (150 mm) and Larger: Self- adhesive pipe markers. Use color-coded, self-adhesive plastic tape, at least 1-1/2 inches (38 mm) wide, lapped at least 3 inches (75 mm) at both ends of pipe marker, and covering full circumference of pipe.
B. Locate pipe markers and color bands where piping is exposed in finished spaces; ma- chine rooms; accessible maintenance spaces such as shafts, tunnels, and plenums; and exterior non-concealed locations as follows:
1. Near each valve.
2. Near each branch connection, excluding short branches for fixtures. Where flow pattern is not obvious, mark each pipe at branch.
3. Near penetrations through walls, floors, ceilings, and non-accessible enclosures.
4. At access doors, manholes, and similar access points that permit view of con- cealed piping.
5. Near major equipment items and other points of origination and termination.
6. Spaced at maximum intervals of 50 feet (15 m) along each run. Reduce intervals to 25 feet (7.6 m) in areas of congested piping and equipment.
3.3 VALVE-TAG INSTALLATION
A. Install tags on valves and control devices in piping systems, except check valves; valves within factory-fabricated equipment units; plumbing fixture supply stops; fau- cets; convenience and lawn-watering hose connections. List tagged valves in a valve schedule.
B. Valve-Tag Application Schedule: Tag valves according to size, shape, and color scheme.
3.4 WARNING-TAG INSTALLATION
A. Write required message on, and attach warning tags to, equipment and other items where required.
3.5 ADJUSTING
A. Relocate mechanical identification materials and devices that have become visually blocked by other work.
3.6 CLEANING
A. Clean faces of mechanical identification devices.
