Preparing for ASTM B117 testing: from method to instrument setup

The TNG1124 Salt Spray Tester is the correct instrument for compliance with ASTM B117, as it provides the required test conditions and specifications for salt spray testing.

Confirming the Method Code

Before procurement, it is essential to confirm that the test method aligns with ASTM B117. This standard specifies the procedures for conducting salt spray tests to evaluate the corrosion resistance of materials. The TNG1124 Salt Spray Tester is specifically designed to meet these requirements, ensuring that the test conditions are accurate and repeatable. The instrument's specifications are aligned with the standard's parameters, including temperature control and test duration, which are critical for valid results.

Identifying the Required Measuring Range

The TNG1124 Salt Spray Tester offers two primary test chamber sizes: 108 L and 270 L. These volumes are suitable for different testing needs, with the 108 L chamber being ideal for smaller samples and the 270 L chamber accommodating larger batches. The test solution volume of 15 L ensures that the chamber is adequately filled to maintain consistent salt concentration throughout the test. These specifications support the ASTM B117 standard by providing a controlled environment where the corrosive effects of salt spray can be accurately measured over time.

Checking the Published Specification Table

The TNG1124 Salt Spray Tester includes precise temperature control settings, with the test chamber temperature set at 35℃±1℃ for NSS (Neutral Salt Spray) and 50℃±1℃ for CASS (Copper Accelerated Salt Spray). The air temperature is maintained at 47℃±1℃ for NSS and 63℃±1℃ for CASS. These temperature ranges are critical for simulating real-world corrosion conditions as defined by ASTM B117. The internal dimensions of the chamber, which are 600x450x400 mm or 900x600x500 mm, ensure that samples are properly positioned and exposed to the test environment without interference.

Requesting a Quotation

Once the method code, measuring range, and specifications have been verified, the next step is to request a quotation. Ensure that the quotation includes the model number TNG1124 and all relevant specifications such as test chamber size, solution volume, and temperature settings. This ensures that the procurement process is aligned with the requirements of ASTM B117 and that the selected instrument will provide reliable and repeatable test results.
