Steps and procedures of salt spray testing

The salt spray test is a kind of corrosion testing that evaluates the resistance of materials and coatings to corrosion by exposing them to an environment that has a large quantity of salt in it. The test is performed by exposing the materials and coatings to an environment that has salt in it. The following is a rundown of the many phases and procedures that make up the salt spray test:

  1. The solution for the salt spray is made by dissolving a certain amount of sodium chloride (NaCl) in water that has been distilled beforehand. The instructions provided by the manufacturer should provide information on the quantity of NaCl that must be used for the solution.
  2. Before the actual testing can begin, the specimens that will be examined have been cleaned and conditioned in accordance with the appropriate standards. This was necessary in order to ensure accurate results.
  3. After this, the samples are transferred into the salt spray test chamber, which is maintained at a certain temperature and relative humidity level during the procedure. After completing this procedure, the testing procedure may now get underway inside the chamber.
  4. Application of a Salt Solution Mist The specimens are covered in a uniform layer of the salt spray solution, which, when applied in such a way that it is sprayed over them, produces an atmosphere that is saturated with salt.
  5. During the course of the test, the specimens are inspected at various time intervals for the presence of corrosion. The test is then carried out for the allotted number of cycles.
  6. Analysis of the Obtained Results The samples are analyzed to detect whether or not corrosion is present, and they are scored according to the kind of the damage, its degree of severity, and the location of the deterioration.
  7. Documentation of Findings: The results of the test are recorded, and a report is created that describes the conditions under which the test was conducted, the specimens that were utilized, and the findings.

Because it is necessary to adhere to the standards that are applicable, it is essential to keep in mind that the various organizations that develop standards may have somewhat distinct procedures and criteria for salt spray testing. Since it is necessary to adhere to the standards that are applicable, it is crucial to keep this fact in mind.

What are the differences of FMVSS 302, UL94 and IEC60695 for flammability test?

Image
The flammability of different materials, such as plastics and other materials used in items such as automobile interiors, electronic devices, and electrical appliances, is evaluated using a number of different standards. Some of these standards are FMVSS 302, UL 94, and IEC 60695. Nevertheless, there are a number of important distinctions between these standards: FMVSS 302 is a specialized standard that was designed for the automotive industry to analyze the flammability of materials used in car interiors. Its purpose is to measure the combustibility of these materials. The UL 94 standard is a more comprehensive regulation that assesses the combustibility of a variety of materials, including plastics, and has applications in a number of different sectors. IEC 60695 is a global standard that is used in the process of assessing the potential for electronic and electrical equipment to catch fire. Testing Procedures The flammability of materials is determined using a variety of testing ...

Abstract In the realm of precision measurement, the calibration of infrared thermometers, including infrared ear thermometers and forehead thermometers, is crucial for ensuring accurate body temperature readings. Black Body Calibrators play a pivotal role in this process, offering highly reliable and stable temperature sources for calibration. This paper provides an in-depth analysis of various calibration devices used for infrared thermometers, with a special focus on the LISUN BBF-1 Black Body Furnace. Through detailed explanations and data tables, this study highlights the importance of Black Body Calibrators in ensuring the accuracy and reliability of infrared temperature measurement devices. Introduction Infrared thermometers, specifically infrared ear thermometers and infrared forehead thermometers, have become increasingly popular due to their non-contact measurement capability and speed. These devices are commonly used in medical settings for quick temperature assessments. Howe...

Accessible parts of equipment with standard IEC 62368 General An accessible part of an equipment is a part that can be touched by a body part. For the purposes of dctermining an accessible part, a body part is represented by one or more of the specified test probes. Accessible parts of an equipment can include parts behind a door, panel, removable cover, etc. that can be opened without the use of a tool. Accessible parts do not include those that become accessible when floor standing equipment having a mass exceeding 40 kg is tilted. For equipment intended for building-in or rack-mounting, or for subassemblies and the like for incorporation in larger equipment,accessible parts do not include those that are not accessible when the equipment or subassembly is installed according to the method of mounting or installation specified in the installation instructions. A part is considered accessible if the instructions or markings intended to be followed require that a person phys...
