ASTM B117 tester models and their published ranges

The Salt Spray Tester (TNG1124) is designed to meet the requirements of ASTM B117, providing reliable and consistent results for corrosion testing.

Specifications and Compliance with ASTM B117

The Salt Spray Tester (TNG1124) is engineered to comply with ASTM B117, a standard that evaluates the corrosion resistance of materials through salt spray testing. One key specification is the test chamber volume, which can be either 108 L or 270 L. This range allows for flexibility in testing different sample sizes while maintaining the required environmental conditions. Another critical specification is the test solution volume, set at 15 L. This ensures a consistent and controlled concentration of salt solution, which is essential for accurate and repeatable results as per ASTM B117.

Temperature Control and Environmental Conditions

Temperature control is vital for the accuracy of salt spray testing. The TNG1124 offers two temperature settings: NSS.ACSS at 35℃±1℃ and CASS at 50℃±1℃ for the test. The ambient air temperature is maintained at 47℃±1℃ for NSS.ACSS and 63℃±1℃ for CASS. These precise temperature controls ensure that the test environment remains within the specified ranges, which is crucial for the validity of the test results under ASTM B117. Proper temperature regulation helps simulate real-world conditions and ensures that the corrosion process is accurately represented.

Chamber Dimensions and Installation

The internal dimensions of the TNG1124 are 600x450x400 mm or 900 x600x500mm, while the external dimensions are 1060X570X1060 mm or 1420 x 980X1285 mm. These dimensions are important for accommodating various sample sizes and ensuring that the test chamber can be installed in different laboratory environments. The 108L model has an external dimension of 1110*560*1100 mm, which is suitable for laboratories with space constraints. The specified dimensions ensure that the instrument can be integrated into existing laboratory setups without compromising the test conditions.

Conclusion

The TNG1124 Salt Spray Tester is a reliable instrument that meets the requirements of ASTM B117. Its specifications, including test chamber volume, test solution volume, temperature control, and chamber dimensions, are designed to ensure accurate and consistent corrosion testing. These features support the standard's requirements, making the TNG1124 a suitable choice for laboratories conducting salt spray tests.
