Plastics piping systems - Brackets for rainwater piping systems - Test method for bracket strength

This standard specifies a method for testing the strength of fixing brackets intended to support plastics rainwater downpipe systems used externally on buildings. It is applicable to both metal and plastics brackets, and determines the amount of residual deformation after removal of a specified test load.

Overview

EN 12095:1997 is a European standard developed by CEN that specifies a test method for evaluating the strength of brackets used in plastic rainwater piping systems. These brackets are essential components designed to securely support external rainwater downpipe systems on buildings. The standard covers both metal and plastic brackets, focusing on determining their residual deformation after applying and removing a specified test load. This ensures the durability and reliability of brackets in rainwater drainage applications.

Key Topics

• Scope of Testing
  EN 12095:1997 defines procedures to assess bracket strength, ensuring they can withstand expected mechanical stresses without permanent deformation.

• Applicable Materials
  The standard applies to brackets manufactured from both plastics and metals intended for external use in rainwater downpipe systems.

• Test Methodology
  The standard outlines how to apply specified loads to the bracket and measure residual deformation post-test, providing a quantifiable measure of bracket performance.

• Performance Requirements
  Brackets must demonstrate sufficient strength to maintain stability of rainwater piping, securing drainage systems against environmental and mechanical stresses.

Applications

This standard is critical to manufacturers, installers, and quality assessors in the construction and plumbing sectors, particularly those involved with:

• External Rainwater Drainage Systems
  Ensuring brackets reliably support plastic downpipes, improving system longevity and safety.

• Plastic Piping Systems Design and Manufacturing
  Guiding bracket design to meet mechanical performance requirements relevant to outdoor conditions.

• Building Maintenance and Inspection
  Providing benchmarks for assessing the integrity of existing rainwater pipe supports during routine building inspections.

• Quality Control in Construction Projects
  Applying standardized strength tests to guarantee compliance with European regulations for drainage components.

Related Standards

Several other standards complement EN 12095:1997 within the broader domain of plastic piping and drainage systems:

• EN 12056 – Gravity Drainage Systems Inside Buildings
  This provides guidelines for internal rainwater drainage systems, complementing the external focus of EN 12095.

• EN 61386 – Conduit Systems for Electrical Installations
  Although focused on electrical conduits, similar mechanical test methods are relevant.

• ISO 9001 – Quality Management Systems
  Applicable for manufacturers to ensure consistent quality in producing compliant brackets.

Summary

EN 12095:1997 is a fundamental standard for ensuring the mechanical strength and durability of brackets supporting plastic rainwater piping systems. By standardizing test methods for bracket strength, both manufacturers and end-users can ensure reliable performance in external drainage applications, contributing to safer and longer-lasting rainwater systems on buildings. This leads to enhanced building protection and compliance with European construction standards.
