Flammability testing plays a crucial role in ensuring the safety and compliance of electrical and electronic products. The vertical flammability test is a key method for assessing the fire resistance of various materials, particularly in electrical equipment, household appliances, and plastic components. This test is widely used to classify materials based on their flame-retardant properties, help...
Introduction The Horizontal Vertical Flame Tester (HVR-LS) is an essential tool for assessing the flammability characteristics of materials used in electrical and electronic products. This article discusses the application of the HVR-LS in evaluating HB & V-level (50W) and 5V-level (500W) materials. These tests are vital for ensuring the safety and compliance of products such as lighting equip...
Introduction The UL flammability rating is a critical standard that classifies materials based on their ability to withstand flame exposure. This rating system is essential for ensuring the safety and reliability of products, especially in industries like electronics, lighting, and household appliances. The UL 94 test method, which includes both horizontal and vertical flammability testing, is wid...
The UL94 horizontal and vertical burning tester is a precision device used to evaluate the combustion performance of materials. It is applicable in research, production, and quality inspection across a wide range of electrical and electronic products and components, including lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical devices, motors, power...
Horizontal and Vertical Flame Test Chamber is a device professionally designed to test the combustion performance and fire resistance of related materials, mainly used in building materials, wires and cables, furniture, automotive interior and other fields, mainly to assess the material’s ability for resist to the spread of fire in potential fire risk, parameters such as toxic gas emission a...
UL94 UL 94is one of the most used flammability tests for determining the relative flammability of plastic materials (Underwriters Laboratories test standard UL 94). Under carefully controlled laboratory circumstances, it evaluates a plastic part’s capacity to put out a flame after it has started, as well as how it will leak in response to a little open flame or radiant heat source. UL94 is a...

What’s use of Horizontal & Vertical Flame Test Chamber? It is used to test the appliances and plastic materials parts of electrical equipment for the horizontal, vertic...
Needle flame test is used to assess products that are prone to electrical or anyother fire hazards this article will look into different flame retardant test methods and how LISUN’s needle flame testers holds up in the market. LISUN ZY-3 Needle flame test LISUN ZY-3 is a needle burner of a specific size (0.9mm) and gas (butane or propane). Burn test at 45° intervals at regular and directed inte...
This HVR-LS Horizontal Vertical Flame Test Chamber meets the requirements of ANSI/UL94, IEC60695-11-3, IEC60695-11-4, IEC60695-11-10, IEC695-2-2 , GB- 4943, GB/T5169.15, GB/T5169.16, GB/T5169.17, GBT5169.22 Standard. Horizontal Vertical Flame Test Chamber uses a bunsenburner with a specified size and a specific gas source (methane or natural gas). According to a certain flame height and a...
Application: The horizontal and vertical flame tester UL94 is mainly used to determine the combustion performance of plastic, rubber or film under a specified fire source to determine its fire resistance level. It is not only suitable for the research, production and quality inspection departments of electrical and electronic plastic or rubber products and their components such as lighting equip...
UL94 flammability test grade is the most widely used plastic material flammability performance standard. It is mainly a fire test standard for plastic box foam materials to evaluate the ability of materials to extinguish after being ignited. According to the burning speed, burning time, anti-drip ability and whether the dripping is burning, there are many methods to determine whether the burning o...
The full name of IEC 60695-11-3 is Test flames – 500 W flames –Apparatus and confirmational test methods. It has been prepared by IEC technical committee 89: Fire hazard testing. We will introduce the IEC 60695-11-3 4.4.1 Requirements. Requirements A standardized 500 W nominal test flame, according to this method, is one that is produced– using hardware according to Figures A.1 and A.2,– s...
