ASTM E2226-23a PDF

Overview

ASTM E2226-23a - Standard Practice for Application of Hose Stream establishes uniform procedures and apparatus for applying a hose stream to building elements following a standard fire-resistance test. Developed by ASTM International, this practice plays an essential role in evaluating the integrity and resilience of a wide range of building assemblies, including wall and partition systems, fire-resistive joint systems, and door assemblies. The standard ensures that the assessment process is consistent, repeatable, and reliable by specifying water pressure, application duration, and procedural details for hose stream testing.

Key Topics

• Standardized Hose Stream Application: Describes the use of a solid stream of water, including the hose size, discharge tip, and pressure requirements, to ensure comparability across different tests and assemblies.
• Post-Fire Exposure Testing: Applies only after a building element has completed standard fire-resistance testing, serving as an additional assessment of durability and integrity.
• Test Configuration and Procedure:
  • Placement and orientation of the nozzle in relation to the test assembly.
  • Water pressure and duration defined according to the fire resistance period.
  • Systematic movement of the hose across the assembly to cover the entire exposed face.
• Assessment Scope and Limitations:
  • Records performance under specific hose stream conditions, considering impact, erosion, and cooling.
  • Does not confirm continued structural integrity or suitability for use post-test.
  • Exposure is not intended to simulate all field conditions or actual firefighting operations.
• Reporting Requirements: Specifies thorough documentation of test conditions, observations, and outcomes, especially relating to penetrations, cracks, and water passage.

Applications

ASTM E2226-23a provides vital value in the fields of building construction, fire safety engineering, and product certification, serving multiple practical applications:

• Fire Resistance Evaluation: Used in conjunction with fire-resistance test methods such as ASTM E119 and NFPA 252 to assess how well building elements resist structural failure, integrity loss, or excessive deformation after fire exposure and cooling by water streams.
• Material and Product Testing: Enables comparison of different construction materials and techniques, providing a benchmark for evaluating innovations in fire-resistant construction products.
• Code Compliance: Supports compliance with building codes and fire safety regulations that mandate hose stream testing of walls, partitions, doors, and joint systems.
• Quality Assurance: Assists manufacturers, inspectors, and regulatory bodies in verifying that products and systems meet industry safety standards regarding fire and post-fire performance.
