LBT-1167 Geosynthetic Material Low-Temperature Brittleness Temperature Tester (New Standard, Multiple‑Method Approach)

Description

Product Introduction

It is used to determine the highest temperature at which a material specimen, under specified conditions, fails upon impact—this temperature is defined as the embrittlement temperature. It enables comparative evaluation of the low‑temperature performance of plastics (per GB/T 5470), JTG 3460‑2026 “Test Procedures for Geosynthetic Materials in Highway Engineering” (Type B specimens), and other elastomeric materials. It can also assess the embrittlement temperatures and relative low‑temperature performance of various rubber materials or vulcanized rubbers with different formulations. Consequently, this instrument is indispensable for scientific research, quality inspection of materials and products, and process control during manufacturing. This equipment is designed in accordance with national standards including GB 1682 “Plastics—Determination of Embrittlement Temperature by the Impact Method” (ISO 974:2000), ASTM D746‑24 “Standard Test Method for Impact Embrittlement Temperature of Plastics and Elastomers,” GB/T 5470‑2008 “Plastics—Determination of Embrittlement Temperature by the Impact Method,” and JTG 3460‑2026 “Test Procedures for Geosynthetic Materials in Highway Engineering.” All technical specifications comply with the relevant national standards.
