TMC Recommended Practices Enter Appeal Period

The Technology & Maintenance Council (TMC) of American Trucking Associations is proposing adoption of the following Recommended Practices.
* Proposed RP 182(T), Troubleshooting 12-Volt
Cranking and Charging Systems Equipped
With Three Terminal Ultracapacitors. This
Recommended Practice (RP) provides
a sequential procedure for evaluating or
troubleshooting the electrical charging and
cranking systems of heavy-duty vehicles
with three-terminal ultracapacitors (UCs)
which utilize the added third "S+" terminal
design during a pilot inspection, preventive
maintenance (PM) inspection, or repair/
diagnostic procedure.
* Proposed RP 184(T), High-Voltage Cable For
Heavy-Duty Truck Wiring Systems. This RP
defines the terminology and specifications for
high-voltage primary or shielded cable that
meets the performance requirements needed to
design and service heavy-duty truck, tractor or
trailer electrical systems.
* Proposed RP 203E(T), Truck/Bus Tire
Regrooving. This RP presents two federal
regulations that must be followed when
regrooving heavy-duty truck and bus tires, and
covers the recommended steps that should be
followed to avoid causing damage to the tire.
* Proposed RP 230C(T), Tire Test Procedures
For Tread Wear, Serviceability and Fuel
Economy. This RP provides guidelines on tire
testing procedures.
* Proposed RP 231C(T), Wheel System
Maintenance Labeling Guidelines. This RP
establishes a standard format for wheel system
maintenance labels that are installed by fleets
and original equipment manufacturers on
trucks, tractors, trailers, chassis, dollies and
other vehicles.
* Proposed RP 232B(T), Inspection Procedures
To Identify Potential Sidewall "Zipper
Rupture" In Truck and Bus Tires. This RP
provides inspection procedures for identifying
potential circumferential ruptures, also known
as "zipper ruptures" on truck and bus tires
(Load Range "F" and higher) and light truck

tires (Load Range "E" and lower) of steel cord
radial construction.
* Proposed RP 239B(T), Commercial Vehicle
Tire Inflation and/or Monitoring Systems
Guidelines. This RP covers current capabilities
and basic operation of tire inflation and
pressure monitoring systems. It is designed to
help fleets select tire inflation and monitoring
systems for commercial truck tires.
* Proposed RP 240B(T), Steel Wheel and Rim
Refinishing Guidelines. This RP provides
guidelines and inspection criteria for steel
wheel and rim refinishing and for evaluating
refinishing suppliers.

Tire Shop Tools and Equipment. This RP
provides guidelines for setting up or making
improvements to tire shop work areas and
service vehicles. These tool and equipment
recommendations apply to the servicing of tire/
wheel assemblies on Class 4-8 vehicles.
* Proposed RP 332C(T), Guidelines For Hoses,
Clamps, and Fittings For Cooling and Charge
Air Cooler Systems. This RP addresses the
proper use of hose clamps used on all engine
support systems. It describes the proper
matching of hose clamp and hose application
on cooling and charge air cooler engine support
* Proposed RP 414C(T), Truck Cab Air
Conditioner Specification Guidelines. This
RP is designed to help industry professionals
reduce heavy-duty truck air conditioner
problems through better specifications when
purchasing and designing new vehicles.
* Proposed RP 445(T), Power Management
Strategies For In-Cab Medical Devices (PAP).
This Recommended Practice (RP) offers
guidelines for specifying and implementing
power management strategies for in-cab, air
pressure medical devices, such as Type A,B
and C positive airway pressure (PAP) devices
used in the treatment of sleep apnea.

* Proposed RP 631C(T), Recommendations
For Wheel End Lubrication. This RP offers
equipment users recommendations and
operational considerations for selecting,
inspecting and using lubricants in wheel
end applications for Class 3-8 trucks, buses,
tractors, and trailers designed for on-highway
* Proposed RP 746A(T), Drawbar Length
Considerations. This RP offers a
comprehensive source of information for fleets
and manufacturers to use when specifying
drawbar lengths on commercial vehicles with
the exception of driveaway/towaway and
stringer-steered applications.
* Proposed RP 1115A(T), Guidelines For
Qualifying Products Claiming a Fuel Economy
Benefit. This RP provides equipment users
with guidelines on how to qualify, or critically
review, product claims of improved fuel
* Proposed RP 1616A(T), Mobile Maintenance
Safety. This RP helps ensure that mobile
maintenance technicians have as safe of a work
environment as possible. This RP outlines
safety protocols and procedures for running a
mobile maintenance operation.
Any party may submit a written request of appeal
of a proposed Recommended Practice (RP). However, the request must be received by the Technology & Maintenance Council within 90 days of
publication of this notice. If no appeals are made
at the end of the 90 days, the RP will be formally
