Corrosion tests are used to protect metal, stone, and other materials from deterioration. Corrosion laboratory testing involves controlled environments and exposure to high relative humidity, high temperatures, and salt atmospheres. It is necessary for commercial, industrial, military, and aerospace products to prevent permanent damage, such as metal corrosion and insulation issues.
Corrosion tests demonstrate how to protect metal, stone, or other materials from deterioration. Corrosion causes rusting of steel or iron used in cars, water pipes, and structures. When conducting corrosion tests, one must consider the environment in which the material will be used. The most common environments include salt fog, immersion, and rapid weathering.
MIL-STD 883 Salt Atmosphere Testing, ASTM B-117 Salt Spray Testing, and RTCA DO-160 Humidity Testing are some of the corrosion test procedures. The equipment is exposed to high relative humidity, high temperatures, and salt atmospheres. After testing, the condition of the device is examined for any physical, mechanical, functional, or electrical issues.
Corrosion laboratory testing is conducted in a controlled environment, and factors such as temperature, humidity, and acidic environments are taken into account. Mass is reweighed after exposure and the initial mass is subtracted to measure the mass loss. Salt spray exposure equipment includes a fog chamber, salt solution reservoir, air supply, and other control mechanisms.
Corrosion laboratory testing is essential for commercial, industrial, military, and aerospace products. Corrosion can cause permanent damage and its negative effects include metal corroding, moving parts becoming stuck or clogged, insulation issues, contact damage, and exposed wiring. It also affects materials, conductors, insulators, chemicals, hygroscopic components, and the thermal properties of the equipment.

ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
