Classification System

Test Pressure Classes

The standard defines classes based on test pressure:

  • Class 1A: 0 Pa (No requirement)
  • Class 2A: 50 Pa
  • Class 3A: 100 Pa
  • Class 4A: 150 Pa
  • Class 5A: 200 Pa
  • Class 6A: 250 Pa
  • Class 7A: 300 Pa
  • Class 8A: 450 Pa
  • Class 9A: 600 Pa
  • Exceptional: > 600 Pa (Special requirements)

Method Classifications

  • Method A: Unprotected
  • Method B: Protected

Testing Requirements

Testing procedures include:

  • Water spray application
  • Pressure differential testing
  • Duration of exposure
  • Water penetration assessment
  • Performance monitoring

Application Guidelines

Recommended Classes by Building Type

  • Class 4A: Protected locations, low-rise buildings
  • Class 5A-6A: Standard residential buildings
  • Class 7A-8A: Commercial buildings, exposed locations
  • Class 9A: High-rise buildings, coastal areas
  • Exceptional: Special applications, extreme conditions

Performance Criteria

Products must demonstrate:

  • No water penetration at specified pressure
  • Maintained functionality after testing
  • Effective drainage systems
  • Proper seal performance
  • Durable weather stripping

Critical Components

  • Weather seals
  • Drainage channels
  • Frame joints
  • Glazing systems
  • Hardware integration

Installation Requirements

  • Proper frame sealing
  • Correct drainage paths
  • Appropriate sill details
  • Weather barrier integration
  • Flashing installation

Important Considerations:

  • Select appropriate class for location and exposure
  • Consider building height and orientation
  • Verify test certificates
  • Ensure proper installation methods
  • Maintain regular inspection schedule
