Mild Steel Electrical Fire Hazard tester, 12kv

The term CKINSTO Electrical Fire Hazard Tester is a collective category covering several specialized pieces of equipment designed to evaluate the flammability and fire-risk potential of electrical and electronic components and materials, particularly plastics and insulation. The tests are crucial for meeting international safety standards and preventing electrical fires. CKINSTO provides individual apparatuses for specific tests as defined by standards like IEC 60695 and UL 94. Key Testing Apparatuses The main testers that fall under the "Fire Hazard Tester" category include: 1. Glow Wire Test Apparatus (GWT) Purpose: To simulate the thermal stress produced by a hot, failed, or overloaded component (like a resistor or conductor) coming into contact with insulating material. Principle: A Nickel-Chromium (Ni/Cr) wire loop is heated to a specified temperature (e.g., $550^{\circ}\text{C}$ to $960^{\circ}\text{C}$) and pressed against the test sample (often a non-metallic part or a finished product) with a defined force ($1.0 \text{ N}$) for a set time (typically 30 seconds). Measurement: Measures the time it takes for the material to ignite and/or self-extinguish (Afterflame Time, Afterglow Time). Standards: Adheres to IEC 60695-2-10, -11, -12 (GWFI and GWIT). 2. UL 94 Flammability Test Apparatus Purpose: To determine the burning characteristics of plastic materials used in devices and appliances. Principle: A specimen is subjected to an open flame from a Bunsen burner in a draft-free chamber, either vertically (V-0, V-1, V-2 ratings) or horizontally (HB rating). Measurement: Measures the time the sample continues to burn after the flame is removed (Afterflame Time), the afterglow time, and whether flaming drips ignite cotton placed below the sample. Standards: Complies with UL 94 and related IEC 60695-11-10 standards. 3. Needle Flame Test Apparatus (NFT) Purpose: To simulate the effect of a small flame that might result from a component fault on nearby parts of an electrical product. Principle: A small, defined flame (produced by a needle burner using Butane/Propane) is applied to the specimen for a set duration. Measurement: Measures the sample's flaming time, glowing time, and whether ignition occurs. Standards: Complies with IEC 60695-11-5. 4. Comparative Tracking Index (CTI) Test Apparatus Purpose: To measure the resistance of solid insulating materials to the formation of a carbonized, conductive path (tracking) on their surface when exposed to an electric field and contaminated by an electrolyte (simulating moisture and impurities). Principle: Uses a precisely controlled voltage applied between two electrodes on the material's surface while drops of electrolyte solution are automatically dispensed. Measurement: Determines the CTI value—the maximum voltage at which the material does not fail by tracking after 50 drops. Standards: Complies with IEC 660112 (ASTM-60112).
