Why do we need to do salt spray test according to ASTM-B117?

The salt spray testing that is specified in ASTM-B117 is an essential technique for determining the level of corrosion resistance possessed by materials and coatings. The test evaluates the capacity of the materials and coatings to withstand the corrosive effects of a salt-laden atmosphere, such as those found in marine or coastal areas. This helps determine how well the materials and coatings perform.

A standardized approach for performing salt spray testing is provided by ASTM-B117. This method assures that the findings obtained from various labs can be compared and interpreted in the same manner. The preparation of the specimens, the analysis of the findings, and the reporting of the results are all included in the standard. The standard also defines the test parameters, which may include temperature, relative humidity, and salt content.

The necessity to verify that goods can withstand corrosive conditions is what drives the need for salt spray testing in accordance with ASTM-B117. This helps to ensure that products can be relied upon. Salt spray is corrosive, and products that are used in environments where it is likely to be present, such as automobiles, components used in aerospace vehicles, electronics, and building materials, among other things, need to be able to withstand its effects in order to preserve their useful life and maintain their functionality.

Testing materials and coatings with salt spray in accordance with ASTM-B117 provides valuable information about the corrosion resistance of those materials and coatings. This information helps to make informed decisions about the selection and use of those materials and coatings for particular applications. The findings of the tests may be used to assess the efficacy of various corrosion protection methods, such as the application of anti-corrosion coatings, as well as comparing the performance of various materials and coatings.

In conclusion, the necessity to assure the durability and dependability of goods in corrosive environments is the driving force behind the need for salt spray testing in accordance with ASTM-B117. ASTM-B117 is a standardized procedure that guarantees uniform and similar findings, in addition to providing vital information on the corrosion resistance of materials and coatings. The outcomes of the tests might be put to use in the process of making educated choices about the kinds of materials and coatings to be used for various purposes.

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 ...

125 Grounding Contact Test 125.1 Grounding receptacles having a 5-15R,5-20R，6-13R，6-20R，7-15R，14-15Ror 15-15R configuration are to be subjected to the tests in this section. 125.2 Previously untested devices are to be used. Each device is to be mounted in a flush device box, or as otherwise intended, with its face in a vertical plane. A nonmetallic faceplate is to be installed if intended. A solid 14 AWG (2.1 mm2) copper conductor is to be connected to the receptacle grounding terminal. GNGPL SB1610_AL 125.3 With the receptacle oriented to create the maximum contact displacement (possible distortion of contact affecting its contact ability), the test pin A. Figure 125.1 is to be fully inserted in the grounding contact. A 5 lb (2.27 kg) weight is to be gradually suspended form the test pin 6 inches (152 mm) from the face of the receptacle. The weight is to be applied for 1 minute, following which, the weight is to be removed. The application of the weight is to be repeated with the rece...

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...
