ASTM B117 FAQ: instruments, ranges and method scope
The Salt Spray Tester (TNG1124) is designed to meet the requirements of ASTM B117, providing accurate and reliable corrosion testing through its precise environmental control and chamber specifications.
How Does the TNG1124 Meet the Requirements of ASTM B117?
The TNG1124 Salt Spray Tester is specifically engineered to comply with ASTM B117, which is the standard for salt spray testing of coatings. This standard requires precise control of temperature and humidity to simulate corrosive environments. The TNG1124 achieves this by maintaining a test chamber temperature of 35℃±1℃ for NSS (Neutral Salt Spray) and 50℃±1℃ for CASS (Copper Accelerated Salt Spray), ensuring accurate simulation of real-world corrosion conditions.
What Are the Key Specifications of the TNG1124 That Support ASTM B117 Testing?
The TNG1124 features a test chamber volume of 108 L or 270 L, which is essential for ensuring uniform exposure of test samples. Additionally, the test solution volume of 15 L supports consistent salt spray concentration, a critical factor in ASTM B117 testing. These specifications support the standard's requirement for controlled and reproducible testing conditions.
What Are the Temperature and Humidity Control Capabilities of the TNG1124?
The TNG1124 maintains a test chamber temperature of 35℃±1℃ for NSS and 50℃±1℃ for CASS, as specified in ASTM B117. The temperature of the air within the chamber is controlled at 47℃±1℃ for NSS and 63℃±1℃ for CASS, ensuring that the test environment remains stable and consistent throughout the testing process.
What Are the Physical Dimensions of the TNG1124 and Why Are They Important?
The TNG1124 has an interior dimension of 600x450x400 mm or 900x600x500 mm, with an external dimension of 1060x570x1060 mm or 1420x980x1285 mm. The 108L model has an external dimension of 1110*560*1100 mm. These dimensions are important for ensuring that the instrument fits within laboratory spaces while allowing for proper airflow and sample placement, which are critical for meeting the requirements of ASTM B117.
