ASTM B117 Salt Spray Testing of Coated Plastic Storage Plastics
The ASTM B117 salt spray test is a standard procedure used to evaluate the resistance of materials, especially coatings on metals and plastics, to atmospheric corrosion. This method simulates the corrosive environment caused by sea spray or industrial atmospheres containing acidic condensation. In this service page, we focus specifically on coated plastic storage containers, which are exposed to harsh environmental conditions that can lead to degradation over time.
Coated plastic storage containers used in various industries such as chemical manufacturing, pharmaceuticals, and food processing must withstand prolonged exposure to salt spray. The ASTM B117 test is crucial for ensuring the integrity of these containers, thereby protecting stored materials from contamination or spoilage. The test helps manufacturers comply with regulatory requirements while also extending the useful life of their products.
The process involves exposing the coated plastic samples to a continuous stream of neutral salt water aerosol in a closed chamber maintained at 35°C (95°F) and a relative humidity of at least 95%. The test duration can vary depending on the material's expected service life, but it typically ranges from 48 hours up to several hundred hours. During the test, the appearance, adhesion, thickness, and chemical composition of the coating are monitored.
For coated plastic storage containers, the primary focus is on ensuring that the coating remains intact after exposure. Any signs of corrosion, rusting, or degradation of the coating indicate insufficient protection against environmental factors like salt spray. This information is critical for quality managers and compliance officers who need to ensure their products meet industry standards.
Compliance with ASTM B117 helps manufacturers avoid costly recalls and legal issues associated with product failures due to premature deterioration. Additionally, this testing supports the development of new materials by providing data on how different formulations perform under real-world conditions. R&D engineers can use these results to improve existing products or innovate entirely new solutions.
For procurement teams involved in sourcing materials for storage containers, ASTM B117 salt spray testing offers a reliable method to assess suppliers' capabilities and ensure consistent quality across batches of products. By selecting only those suppliers who pass this rigorous test, companies can maintain high standards throughout their supply chain.

Why Choose This Test
The ASTM B117 salt spray test is essential for several reasons, primarily because it provides a standardized way to assess the corrosion resistance of coated plastic storage containers. This testing ensures that manufacturers and suppliers can deliver products that meet stringent quality standards and regulatory requirements.
One key advantage of this test is its ability to simulate real-world conditions accurately. By subjecting coated plastic samples to a continuous salt spray environment, it helps identify potential weaknesses in the coating before they become critical issues during actual use. This early detection allows manufacturers to address any shortcomings promptly, improving overall product reliability.
Another significant benefit is the confidence it brings to customers and stakeholders. Passing ASTM B117 signifies that a manufacturer has met industry best practices for corrosion protection. This can be particularly important when dealing with sensitive materials or high-risk applications where even minor failures could have severe consequences.
The test also supports continuous improvement efforts within companies. By regularly submitting products to this test, manufacturers can track trends over time and make informed decisions about material choices, formulation adjustments, or process improvements.
Lastly, compliance with ASTM B117 enhances a company's reputation among clients and partners. It demonstrates a commitment to excellence in quality assurance and environmental responsibility, which are increasingly valued by modern consumers and businesses alike.
Quality and Reliability Assurance
The ASTM B117 salt spray test plays a pivotal role in maintaining high levels of product quality and reliability across various sectors. For manufacturers, this test offers valuable insights into the performance characteristics of their coated plastic storage containers under extreme environmental conditions.
By conducting rigorous testing, companies can identify any potential flaws early on, allowing for corrective actions to be taken before significant damage occurs. This proactive approach not only protects against costly repairs or replacements but also enhances customer satisfaction by delivering dependable products.
The results of the ASTM B117 test serve as a benchmark for comparing different materials and formulations. Companies can use this data to optimize their processes, select superior raw materials, or develop innovative coating technologies that outperform competitors.
Moreover, compliance with this standard boosts credibility within the industry and among regulatory bodies. It shows adherence to recognized international standards like ISO 12944:2017 'Corrosion protection in marine environments'. Such recognition fosters trust between buyers and sellers, fostering long-term business relationships.
In conclusion, ASTM B117 salt spray testing is an indispensable tool for ensuring the quality and reliability of coated plastic storage containers. Its importance cannot be overstated as it contributes significantly to enhancing product performance, customer satisfaction, and market competitiveness.
