Technical Specifications

Flame Spread Index (FSI) and Smoke Developed Index (SDI)

Rating for ABS, PVC, and CPVC

The ASTM E 84/UL 723 test protocol is speciﬁed by the Uniform and International Mechanical Codes to evaluate a material’s

suitability for inclusion within unducted return air plenum spaces.

Charlotte Pipe manufactures all of our CPVC CTS pipe and ﬁttings from FlowGuard Gold

CPVC pipe and ﬁttings compounds

which are purchased directly from Lubrizol. These are the same compounds used by their other customers/converters to the

best of our knowledge. Further, Charlotte Pipe and other converters have provided our customers (contractors, engineers, code

ofﬁcials, and distributors) in the past with copies of the Lubrizol test reports indicating that Lubrizol products conform to

ASTM E 84. In this listing (ICC-ES Report PMG-1264), which is available upon request, Lubrizol and ICC Evaluation Service

represent that the Lubrizol pipe and ﬁtting systems are plenum compliant. Charlotte Pipe defers to this listing report.

DESIGN & ENGINEERING DATA

Pipe or fittings may be damaged by contact with

products containing incompatible chemicals resulting in

property damage or personal injury.

• Verify that paints, thread sealants, lubricants, plasticized

PVC products, foam insulations, caulks, leak detectors,

insecticides, termiticides, antifreeze solutions, pipe

sleeve, firestop materials or other materials are

chemically compatible with CPVC.

• Do not use edible oils such as Crisco

for lubricant.

• Read and follow chemical manufacturer's literature

before using with piping materials.
