Overview

ASTM E2463-19: Standard Performance Specification for Cargo Bed Cover (CBC) M105A2 Trailer, Type II is an internationally recognized standard developed by ASTM. This specification outlines performance criteria for the Type II Cargo Bed Cover, a removable, rigid wall enclosure designed to mount onto the M105A2 1.5-ton, 2-wheel cargo trailer. The Type II CBC is utilized to provide both environmental protection and enhanced security for mission-critical equipment and items of general transport, especially in military and demanding field operations.

This standard establishes comprehensive requirements covering design, construction, performance, safety, and suitability of CBCs in various transport and environmental conditions, ensuring compatibility and reliability when deployed with M105A2 trailers.

Key Topics

• Performance Criteria: Defines the expected structural strength, weight limits, payload capacities, and environmental durability of the Type II CBC.
• Design & Construction: Details component dimensions, materials, finish, and interface specifications for ease of installation and part interchangeability.
• Safety and Protection: Includes blackout requirements, chemical resistance, venting, and secondary exit provisions for operational safety and security.
• Transportability: Sets out CBC operational integrity across rail, fixed wing, helicopter sling load, and highway transport, meeting U.S. Department of Defense and NATO mobility standards.
• Quality Assurance: Specifies manufacturer and contractor responsibilities for quality inspections, first article testing, and ongoing conformity assessments.
• Environmental and Chemical Resistance: Addresses humidity, UV, temperature ranges, marine exposure, sand/dust ingress, flame resistance, and fungal growth prevention.

Applications

The practical applications of ASTM E2463-19 are critical for:

• Military Logistics: Ensuring secure and weather-resistant transport of sensitive equipment in field operations, peacekeeping missions, or disaster response using the M105A2 trailer.
• Government Procurement: Providing clear, measurable criteria for the acquisition and inspection of cargo bed covers used by defense and government agencies.
• Commercial Manufacturing: Guiding CBC manufacturers in meeting stringent Department of Defense specifications for interoperability, durability, and safety.
• Maintenance and Upgrades: Supporting operators and logistic teams with standards for spare parts interchangeability and CBC mounting cycles, minimizing downtime and maintenance efforts.
• International Operations: Facilitating cross-border compatibility and compliance with standardization requirements recognized by NATO and major defense partners.

Related Standards

Operators, manufacturers, and procurers of Type II CBCs should also consult the following related standards:

• ASTM E631: Terminology of Building Constructions
• ASTM E1749: Terminology Relating to Rigid Wall Relocatable Shelters
• ASTM E1925: Specification for Engineering and Design Criteria for Rigid Wall Relocatable Structures
• ANSI/ASQC Z1.4: Sampling Procedures and Tables for Inspection by Attributes
• SAE AS8090: Mobility, Towed Aerospace Ground Equipment
• MIL-STD-129: Military Marking for Shipment and Storage
• MIL-STD-810: Environmental Engineering Considerations and Laboratory Tests
• MIL-DTL-53072: Chemical Agent Resistant Coating (CARC) System Procedures

Referring to these standards in conjunction with ASTM E2463-19 ensures comprehensive quality, safety, and operational effectiveness in the deployment and lifecycle management of cargo bed covers for military trailers.

tested as specified in 4.2.15.2.1.
5.2.3 Quality Conformance Inspection—Unless otherwise specified, sampling for inspection shall be performed in accordance
with ANSI/ASQC Z1.4-2003.
5.2.3.1 Component and Material Inspection—In accordance with 4.15.1, components and materials shall be inspected in
accordance with all the requirements of referenced documents unless otherwise excluded, amended, modified, or qualified in this
specification or applicable purchase document.
5.2.3.2 End Item Visual Examination—The end item shall be examined for the defects listed in Table 3. The lot size shall be
expressed in units of one Type II CBC. The sample unit shall be one Type II CBC. The inspection level shall be II and the AQL,
expressed in terms of defects per hundred units, shall be 4.0 for major defects and 6.5 for total (major and minor combined) defects.
5.2.3.3 End Item Dimensional Examination—The end item shall be examined for conformance to dimensions specified. Any
dimension not within the specified tolerance shall be classified as a defect. The lot size shall be expressed in units of one shelter.
The sample unit shall be one shelter. The inspection level shall be II and the AQL, expressed in terms of defects per hundred units,
shall be 4.0.
