Full title and description

ASTM E1925-25 — Specification for Engineering and Design Criteria for Rigid Wall Relocatable Structures. This standard defines performance, material, and design criteria for rigid-wall relocatable structures (RWRS), covering both expandable and non‑expandable units. It establishes requirements for materials, corrosion protection, human handling safety, transportability, structural loads, environmental resistance, and a suite of required tests (transport, drop/impact, air/water tightness, thermal and solar loads, fungus and flame resistance, electromagnetic considerations, and lifting/towing provisions).

Abstract

ASTM E1925-25 provides engineering and design guidance and mandatory acceptance criteria for the development and verification of rigid wall relocatable structures intended for multi‑mode transport and use in a range of operating environments. The standard is intended to ensure RWRS durability, safe handling, and functional performance under defined mechanical, environmental, and transport conditions by specifying construction practices, material limitations, and test requirements.

Scope

This specification applies to the design and verification of rigid wall relocatable structures (RWRS) used as shelters, temporary buildings, or transportable enclosures. It covers materials and workmanship, structural and panel performance, methods and criteria for transportability (air, rail, road, forklift handling), environmental resistance (temperature extremes, solar loading, humidity, marine atmosphere, blowing sand, ultraviolet exposure), safety and handling provisions (lifting, towing, leveling), and required verification tests (drop/impact, air and water tightness, flame and fungus resistance, electromagnetic interference considerations, and load testing). Units designed to this specification are intended to be operable in a variety of environments without degradation and to meet specified transport and handling modes.

Key topics and requirements

• Material selection and corrosion protection; avoidance of intimate contact of dissimilar metals to prevent galvanic corrosion.
• Human‑handling safety: specification of materials that do not cause skin irritation or injury during handling and transport.
• Transportability requirements: design provisions for air transport, rail and ground mobility, forklift handling, and securement for multiple transport modes.
• Structural criteria: roof, floor, door and panel attachment point loads; squareness and panel flatness limits; leveling and lifting provisions.
• Environmental resistance tests: temperature/shock, solar load and heat transfer, humidity, marine atmosphere, blowing sand, and UV exposure.
• Durability and safety testing: flame resistance, fungus resistance, drop/impact (flat and rotational), tow and dragging simulations, and drop shock tests.
• Functional and integrity tests: air tightness, water tightness, blackout/opacity where required, and electromagnetic interference (EMI) provisions.
• Verification and acceptance: test procedures and pass/fail criteria that must be met before acceptance.

Typical use and users

Manufacturers and designers of relocatable shelters and modular enclosures, procurement organizations (including military and disaster‑response buyers), structural and materials engineers, test laboratories performing acceptance testing, and facility planners specifying temporary or transportable building systems. The standard is used to guide product design, specify acceptance tests in contracts, and support procurement and certification decisions for RWRS products.
