Standard Test Method for Measurement of Backpack Capacity
SIGNIFICANCE AND USE
4.1 Many consumers use the capacity measurement as a key specification to determine the backpack size suitable for their requirements.
SCOPE
1.1 This test method determines and standardizes an unextended and extended capacity for backpacks and related bags. Related bags include lumbar packs, soft rucksacks, internal and external frame packs, duffel bags, and travel packs.
1.2 This test method is designed to provide a means whereby manufacturers and consumers may have a consistent means to compare pack volumes.
1.3 This test method does not take into consideration areas of the backpack that are not completely enclosed by fabric such as mesh pockets, water bottle holders, and compressor pockets.
1.4 For practical purposes this test method cannot be used to measure capacities less than 4 L.
1.5 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.
1.6 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.

Overview
ASTM F2153-07(2018) - Standard Test Method for Measurement of Backpack Capacity was developed by ASTM International to provide a universal, reproducible procedure for determining and comparing the internal volume of backpacks and related bags. This standard is significant in the outdoor, travel, and sporting goods industries, offering a standardized measurement method so that manufacturers and consumers can make direct and consistent volume comparisons between pack products. ASTM F2153 applies to a range of pack types, including internal and external frame backpacks, lumbar packs, rucksacks, duffel bags, and travel packs.
Key Topics
- Standardization of Capacity Measurement: Establishes a consistent way to define, measure, and report the volume of all enclosed compartments in a backpack.
- Types of Bags Covered: Includes backpacks, soft rucksacks, internal/external frame packs, lumbar packs, duffel bags, and travel packs.
- Defined Terms:
- Unextended capacity: The volume including all compartments with extensions closed.
- Extended capacity: The volume with all compartments and extensions maximized.
- Test Method Overview:
- Packs are filled with standardized 20-mm plastic balls to their fullest usable volume (extended), then reduced to unextended volume.
- The contents are transferred to and measured in a rigid, calibrated cylinder.
- The method does not account for areas not fully enclosed by fabric, such as mesh pockets or exterior bottle holders.
- Not recommended for capacities below 4 liters.
- Scope Limitations: Safety, health, and environmental concerns are outside the scope; users must determine regulatory compliance for their own scenarios.
Applications
- Outdoor Equipment Industry: Manufacturers can objectively compare and advertise the pack volume of backpacks, duffels, and related products.
- Consumer Purchasing: Enables buyers to make informed decisions based on consistent and reliable capacity data, helping select the optimal bag size for hiking, camping, travel, or daily use.
- Product Testing and Development: Provides a testing framework for R&D departments in outdoor and sporting goods companies to benchmark and refine bag designs.
- Retail and E-Commerce: Retailers and online platforms can list standard capacity figures, enhancing transparency and comparability across brands and product lines.
- Quality Control & Certification: Ensures that the stated capacity specification aligns with international best practices, which can assist in meeting marketplace and regulatory requirements.
Related Standards
- ISO Standards on Luggage and Bags: For additional measurement and quality benchmarks relevant to the global market.
- ASTM F08 Committee Standards: Standards focused on sports equipment and outdoor gear, contributing to the overall quality and safety of consumer products.
- WTO TBT Principles: This standard was developed in accordance with internationally recognized standardization principles established by the World Trade Organization's Technical Barriers to Trade Committee.
Practical Value
Using ASTM F2153-07(2018) ensures that backpack capacity measurements are trustworthy, verifiable, and comparable worldwide. Adopting this standard benefits both manufacturers seeking to communicate product features accurately and consumers who rely on clear specifications to choose the right gear. Its implementation supports product integrity, market competition, and customer satisfaction in the outdoor and travel goods sectors.
