ASTM B117 is a standard test method that determines the corrosive effects of salt on metallic items. The standard is most commonly used for accelerated corrosion testing services. This procedure creates a controlled corrosive environment that is used to generate data on the relative corrosion resistance for metal and coated metal test specimens exposed in specific test chambers. Corrosive resistance of different metals is compared, and corrosion creep along with coating adhesion are determined. The results are reported as concentration or specific gravity.

ASTM B117 Salt Spray (Fog) Testing
ASTM B117 is a standard test method that determines the corrosive effects of salt on metallic items. The standard is most commonly used for accelerated corrosion testing services. This procedure creates a controlled corrosive environment that is used to generate data on the relative corrosion resistance for metal and coated metal test specimens exposed in specific test chambers. Corrosive resistance of different metals is compared, and corrosion creep along with coating adhesion are determined. The results are reported as concentration or specific gravity.
Scope:
ASTM B117 test method is used to create and maintain the salt spray (fog) test environment that impacts many industries with regard to quality control. The test ASTM B117 is used to compare the corrosive resistance of different metals, determine suitable materials for a specific environment, and determine corrosion creep and coating adhesion. This test provides useful information for developing coatings and new materials. The industries such as aircraft, transport, paint, infrastructure, and automotive benefit from these tests. The kind of specimens evaluated, the evaluation criteria chosen, as well as the control of the operating factors, have a significant impact on the reproducibility of results in salt spray exposure.
ASTM B117 Salt SprayTest procedure:
For the ASTM B117 test, a metallic sample is placed in a controlled chamber. The sample is sprayed at different angles and locations with a salt solution. The salt concentration ranges from 3.5-20 % and usually is higher than that in the atmosphere. The chambers required for handling large samples come in different sizes and designs, ranging from small sizes to walk-in rooms.
To create hot and humid air for ASTM B117 testing, a humidifying tower with hot and deionized water is provided, which is accomplished by bubbling compressed air via the tower. Then, the salt solution is mixed with hot and humid air at the nozzle, and a corrosive fog is formed. The relative humidity produced by this fog is 100 %. If lower humidity conditions are desired, the air is blown into the chamber’s exposure zone.
Unless otherwise specified in the specifications covering the material or product being tested, the test shall be continuous for the entire duration of the test period. The period of exposure shall be as designated by the specification covering the material or product being tested.
Unless otherwise specified in the specifications covering the material or product being tested, specimens shall be treated as follows at the end of the test:
The specimen shall be carefully removed.
Specimens may be gently washed or dipped in clean running water not warmer than 38°C to remove salt deposits from their surface and then immediately dried.
A careful and immediate examination shall be made as required by the specification covering the material or product being tested.

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.
