Overview

ASTM B660-23: Standard Practices for Packaging/Packing of Aluminum and Magnesium Products specifies industry-accepted methods for preparing aluminum and magnesium products for storage or shipment, whether for domestic or international destinations. Developed by ASTM International, this standard ensures that such products arrive at their destination in optimal condition, by offering guidelines for avoiding damage during handling, storage, and transportation. The practices address critical risks such as mechanical damage (bending, denting, scratching) and corrosion (including water staining).

Key Topics

• Purpose and Scope:

  • Provides standardized packaging and packing methods for aluminum and magnesium products.
  • Applies to both storage and shipping scenarios, including export shipments.
  • Covers requirements for both military (Level A protection) and commercial packaging.

• Protection Levels:

  • Level A: For the most severe conditions, such as rough handling, multiple handling scenarios, or extended in-transit storage.
  • Commercial Packaging: Sufficient for immediate use or short-term, climate-controlled storage.

• Types of Damage Covered:

  • Mechanical Damage: Includes bending, crushing, denting, or scratching during handling, storage, or transportation.
  • Corrosion and Water Staining: Caused by exposure to water, humidity, or condensation.

• General Packaging Guidance:

  • Mandates use of materials and packaging methods that adequately protect contents.
  • Requires consideration of lifting, hoisting, and forklift handling for heavy packages.
  • Interleaving materials, coatings, and suitable wraps are recommended to avoid surface damage or reaction.

Applications

Standard ASTM B660-23 is essential for organizations involved with the production, distribution, and storage of aluminum and magnesium products, particularly:

• Manufacturers and Fabricators:
  Ensures products are properly preserved and protected until they reach end users, preventing costly rework or scrap due to shipment damage.

• Exporters and Logistics Providers:
  Assists shippers in meeting international packaging best practices, reducing the risk of claims for damaged goods and ensuring customs compliance.

• Military and Defense Contractors:
  Specifies Level A preservation and packing, aligning with rigorous Department of Defense requirements.

• Warehousing and Storage Facilities:
  Enables warehouses to maintain material quality during prolonged storage by using standardized packing procedures and materials.

• End Users:
  Delivers products in prime condition by minimizing surface defects and corrosion risks.

Practical value: By following ASTM B660-23, companies can reduce product loss, improve customer satisfaction, and demonstrate compliance with industry and regulatory standards for aluminum and magnesium packaging.

Related Standards

When implementing ASTM B660-23, several other standards and specifications are referenced for supporting materials and methods:

• ASTM D3951: Practice for Commercial Packaging.
• ASTM D779: Test Method for Water Vapor Resistance of Packing Materials.
• ASTM F1667: Specification for Fasteners (nails, spikes, staples) used in packaging.
• MIL-STD-3010: Packaging materials test procedures for military applications.
• MIL-PRF-121: Requirements for greaseproof, waterproof, flexible, heat-sealable barrier materials.
• APA-PS1: U.S. Standard for Construction and Industrial Plywood.
• ANSI/AHA A135.4: Standard for Hardboard.

Summary

Adopting ASTM B660-23 for the packaging and packing of aluminum and magnesium products ensures protection against damage, regulatory compliance, and effective logistics management. This standard provides clear, practical guidelines for industry stakeholders seeking to maintain material integrity throughout the supply chain and is an authoritative reference for both commercial and defense-related environments.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: B660 − 21 B660 − 23
Standard Practices for
Packaging/Packing of Aluminum and Magnesium Products
This standard is issued under the fixed designation B660; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 These practices describe methods of packaging/packing aluminum and magnesium products, in preparation for storage or
shipment, both foreign and domestic. Assuming proper and normal handling in transit, these practices are designed to deliver the
products to their destination in good condition. For DOD redistribution, see Supplementary Requirements.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.3 Aluminum and magnesium products must be preserved and packed so as to be adequately protected from possible damage
during shipment and storage. Major damage types are:
1.3.1 Mechanical, including bending, crushing, denting, scratching, or gouging during handling and storage; and abrasions
resulting from vibration during transport of the material.
1.3.2 Corrosion, or water stain, resulting from exposure of packed material to water, either externally applied, or as condensate
caused by temperature variations in a humid atmosphere.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.2 Internal Packaging Materials:
5.2.1 Material Compatibility—Internal packaging materials shall not adversely affect the contents.
5.2.2 Blocking and Bracing—Articles not completely filling the shipping container shall be blocked, braced, fastened, or otherwise
secured. Articles having projecting parts that may be broken or may puncture the container shall be rigidly supported, suspended,
or otherwise protected. Clearance of at least 1 in. (25.4 mm) shall be provided between projecting parts and the adjacent inside
face of the container. Blocking and bracing shall be prevented from coming in direct contact with any unprotected surface of the

commensurate with their weight, size, and intended mode of transportation to ensure safe and efficient movement.
5.3.2 Hoisting—Convenient means shall be provided on all shipping containers (except Figs. S1.1-S1.4) and pallets weighing
more than 200 lb (90.72 kg) gross which will permit hoisting by attaching suitable slings at the bottom of the containers and pallets.
5.3.3 Forklift Truck Compatibility—Unless otherwise specified herein and except Figs. S1.1-S1.4, boxes, containers, and pallets
B660 − 23
grossing over 200 lb (90.72 kg) must be capable of being handled from at least two sides by forklift trucks. For DOD use, standard
40 by 48 in. (1016 by 1219.2 mm) pallets must have four-way forklift entry. Openings shall be a minimum of 3 in. (76.2 mm) high
and at least 20 in. (508 mm) apart inside-to-inside, symmetrically about the center of balance. Containers may have a single
opening 40 in. (1016 mm) wide or more to provide forklift access.
