EN 13538-3:2016

Overview

EN 13538-3:2016 is a European Standard developed by CEN that specifies precise methods for measuring the dimensional characteristics of sleeping bags, specifically focusing on volume under load and the easiness of packing. This standard applies to sleeping bags filled with feather and/or down and provides a uniform approach to quantify how much volume a sleeping bag occupies when compressed, as well as how easy it is to pack. It is essential for manufacturers, testing laboratories, and quality control departments involved in the production and evaluation of sleeping bags.

Key Topics

• Volume Under Load Measurement
  The standard describes a method to measure the volume of a sleeping bag when compressed inside a cylinder under a specified load. This reflects the residual volume after compression, which impacts packing and transport convenience.

• Easiness of Packing Calculation
  The easiness of packing is calculated as a ratio combining the volume under load with the dimensions of the sleeping bag when packed in its transport cover. This provides an index value that helps compare different sleeping bag models in terms of packing efficiency.

• Test Equipment and Procedure
  Measurement requires a specific setup including a cylindrical tube, a cylindrical load of precise mass, and tools for accurate height measurement. Conditioning of sleeping bags under controlled temperature and humidity ensures consistent testing conditions.

• Standardized Reporting
  The standard outlines the required test report elements, ensuring uniform communication of results including sample identification, measured values, and any deviations from the testing procedure.

Applications

• Product Development
  Sleeping bag manufacturers use EN 13538-3:2016 to design bags that optimize compressibility and packing ease, directly influencing consumer satisfaction and product competitiveness.

• Quality Assurance
  Consistent measurement of volume under load allows quality control teams to verify product conformity to design specifications and durability standards.

• Consumer Information
  Retailers and brands can provide reliable data on packing volume and handling convenience, aiding consumers in selecting sleeping bags suitable for specific outdoor activities like hiking, camping, and backpacking.

• Comparative Testing
  Testing laboratories perform standardized tests using this European Standard to benchmark different sleeping bags and provide certification or compliance statements.
