Proper waterproofing is important in the construction and industrial services for protecting structures and equipment. Reliable waterproofing materials are needed for roofing, underground works, and protective coatings for electronic devices, along with global waterproofing standards comprehension.
With the development, production, selling, designing and construction of waterproof materials, Huafeng Waterproof Materials Co., Ltd., formerly Weifang Huafeng Waterproof Materials Co., Ltd., is one of the high-tech enterprises that continues to lead in creation technology. Through their location in Shouguang City, Shandong Province, a national base for building waterproof materials research and production, Huafeng is known to always offer quality products which meet international standards.
In this article, the most important domestic and international standards for waterproofing are highlighted, paying special attention to the widely used IP (Ingress Protection) rating and its relevance towards the applications of waterproof materials.
What is the IP Rating System?
The IP rating, defined by the International Electrotechnical Commission (IEC), measures the protection level of electrical enclosures against intrusion from solid particles (dust) and liquids (water). Although originally designed for electrical and electronic equipment, the IP standard is a valuable benchmark for waterproof materials in various industries.
-
The first digit (0-6) indicates the degree of protection against solid objects.
-
The second digit (0-9) indicates the degree of protection against liquids.
Examples of IP ratings:
-
IP65: Dust tight and protected against water jets from any direction.
-
IP67: Dust tight and can withstand immersion in water up to 1 meter for 30 minutes.
-
IP68: Dust tight and suitable for continuous immersion, with specific conditions set by the manufacturer.
Understanding IP ratings helps engineers and manufacturers select appropriate waterproof materials for specific environmental conditions, ensuring long-term durability.
Chinese Waterproof Standards
China has established comprehensive standards to regulate waterproof materials used in construction. Some key standards include:
-
GB 50108-2011 – Code for waterproofing of underground engineering.
-
GB 50208-2011 – Quality acceptance specifications for underground waterproofing.
-
GB/T 328 series – National standards for waterproof membranes.
-
JC/T 1066-2021 – Polymer cement waterproof coatings.
-
GB/T 23457-2017 – Spray-applied polyurea waterproof coatings.
These standards cover physical properties such as tensile strength, impermeability, flexibility, and adhesion, guaranteeing reliable performance in different climates and applications.
International Standards: ASTM and EN
To meet global market demands, waterproof materials must also comply with internationally recognized standards.
ASTM Standards (USA)
-
ASTM D1970: Specification for self-adhering polymer-modified bituminous sheet materials used as waterproofing underlays.
-
ASTM D570: Test method for water absorption of plastics.
-
ASTM D412: Test methods for tensile properties of rubber materials.
EN Standards (Europe)
-
EN 1928: Test methods for determining the watertightness of roofing membranes.
-
EN 12311: Test methods for mechanical properties such as tensile strength and elongation.
-
EN 1296: Artificial weathering tests for waterproof coatings.
These rigorous standards emphasize durability, environmental resistance, and material longevity, which are vital for international projects.
