Overview
EN 772-7:1998 is a European Standard developed by CEN that defines a precise method for testing the water absorption characteristics of clay masonry damp proof course (DPC) units. The standard specifies the procedure of boiling these masonry units in water for a fixed period to determine their water absorption capacity. This test is essential to evaluate the durability and performance of damp proof course clay masonry units in construction, ensuring they effectively prevent moisture ingress.
Key Topics
- Scope: Applies specifically to clay masonry damp proof course units and their water absorption properties.
- Test Method: Involves boiling the masonry units in water, simulating harsh moisture exposure conditions.
- Water Absorption Determination: Measurement of water uptake after exposure to boiling water, reflecting potential long-term behavior in damp environments.
- Specimen Preparation: Guidelines for preparing clay masonry units before testing to ensure uniformity.
- Fixed Boiling Duration: Standardizes the time specimens remain in boiling water to maintain consistency.
- Quality Control: Provides a means for manufacturers and testers to verify compliance with moisture resistance requirements.
Applications
- Construction Industry: Ensures damp proof course clay masonry units meet prescribed water absorption limits to maintain building integrity.
- Quality Assurance: Used by manufacturers to test batches of damp proof course units for consistency in moisture resistance.
- Laboratory Testing: Provides a standardized test for laboratories assessing masonry units for durability under moisture exposure.
- Moisture Protection: Helps architects and engineers select suitable masonry DPC units to prevent rising damp and moisture-related structural issues.
- Regulatory Compliance: Assists in verifying compliance with building regulations and European standards related to moisture control in masonry construction.
