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...

Introduction Materials utilized in building, transportation, electronics, and maritime applications all face difficulties outdoors. The durability and performance of these materials may be negatively affected by exposure to water, humidity, temperature changes, and corrosive chemicals. To determine how well a material or coating will hold up in the elements, it must undergo testing in a salt spray chamber. In this article, we’ll look at why salt spray testing is so useful for gauging outdoor durability, how salt spray chambers work, and what kinds of businesses might benefit from using them. Understanding Outdoor Durability and Corrosion The term “outdoor durability” is used to describe a material’s capacity to last and function normally in the elements. Corrosion is a severe problem in outdoor settings because it causes deterioration in materials, structural collapse, and operational problems. When assessing weather resistance, knowledge of the causes and processes of corrosion is cru...

Introduction Data centers house many servers, networking devices, and crucial data storage systems, and are therefore essential to the current IT architecture. Access to digital services must be consistent, thus it’s crucial that these facilities run smoothly. Data centers utilize surge protection techniques, with surge generators playing a crucial role, to prevent voltage surges and transient disturbances that may interrupt operations and cause data loss. This article delves into the value of surge generators in data centers, focusing on how they safeguard vital IT components, keep data secure, and guarantee the constant availability of services. Data center operators and IT professionals who want to increase the resilience and dependability of their facilities would do well to familiarize themselves with the value of surge generators in data centers. Surge Protection in Data Centers Voltage surges may occur in data centers due to a number of different external and internal factors, s...

Gloss is one aspect of visual perception. Considering the psychological impact of products on consumers, it is as important as color. It is defined as “surface attribute”, which makes the object approximate to the shiny or shiny metal texture appearance. Gloss The glossiness of the object surface will be affected by many factors, such as the smoothness after polishing, the quantity and type of coating used, and the quality of the substrate. The manufacturer constantly designs glossy products such as highly reflective car panels, glossy magazine covers, satin black fashion furniture, etc. to maximize the attention of consumers. Gloss is very important for products. Therefore, the gloss value can be obtained by continuous testing of each product or different batches of products. Gloss can also be used to measure the surface quality. For example, the glossiness of the surface coating is reduced, indicating that the surface may need to be reprocessed; Other factors that lead to the reducti...

Retention of Blades Test A flush or self-contained receptacle having a 5-15R,5-20R,6-15R, or 6-20R configuration shall be subjected to the retention of blades test described in this Section. Exception: A receptacle having a 1-15R,5-15R,5-20R,6-15R, or 6-20R configuration and not of the flush or self-contained type may instead be subjected to the Retention of Plugs Test, Section 116. Receptacles having the break-off tab, when provided, removed from one nonidentified terminal are to be subjected to ten conditioning cycles of manual insertion and withdrawal of a standard test gauge, see Figure 111.1. Each of six devices is to be tested. The gauge is to be configured as outlined in Table 111.1. The force applied to insert the gauge for any of the conditioning cycles is not to exceed 40 lbf (178 N). The gauge is to have the dimensions indicated in Figure 111.1 but is not to have holes in the outer ends of the blades. Test Gauge with UL498 Figure 111.1 The standard test gauge is to be config...
