Description
Product Introduction:
Manufactured in accordance with GB/T 8965.1-2020, this product is primarily used for testing the thermal insulation performance of flame‑retardant fabrics—such as those employed in Class A flame‑retardant protective clothing and firefighting suits—when exposed to radiant and convective heat sources. It is widely utilized by specialized labor‑protection‑equipment supervision and inspection stations, research institutes for workplace safety, product quality‑inspection agencies, and manufacturers of flame‑retardant apparel.
Reference standard:
GB/T 8965.1-2020 “Protective Clothing — Flame‑Retardant Protection — Part 1: Flame‑Retardant Garments”
GA 10-2014 “Firefighter Protective Firefighting Suit”
Product Features:
1. The radiant heat source consists of nine T-150 infrared quartz lamps.
2. The convective heat source consists of two Mek components, with an inclination angle of 45°.
4. The flame intensity of the convective heat source can be adjusted using a glass rotameter.
5. The protective barrier can be opened and closed to control experimental access and shield against heat generated by the heat source.
6. The heat radiation flux display shows the heat flux value in real time.
7. The main components include a heat source, a protective grid, a specimen holder and mounting plate, a sample‑clamping plate, a spacing device, a copper calorimeter, a calorimeter mounting module, a data logger, a gas flow meter, and others.
8. It employs computer control and dedicated testing software to automatically perform relevant experiments and process and analyze the data.

YLZ-100 Microcomputer-Controlled Electro-Hydraulic Servo Curbstone Flexural Testing Machine
The YLZ-100 concrete curbstone flexural‑compressive testing machine is used to determine the flexural strength and flexural load of linear curbstones with a length of 1000 mm, as well as the compressive strength of curved curbstones and L‑shaped curbstones with a straight cross‑section. In accordance with JC/T 899‑2016 Concrete Curbstones, it can also be employed to conduct experimental studies on the flexural and compressive strengths of other materials.
The microcomputer-controlled high‑ and low‑temperature electronic universal testing machine consists of the testing machine mainframe, fixtures, a high‑ and low‑temperature chamber, and computer software. The temperature chamber is slid into the mainframe; after opening the chamber door, the specimen is secured in the dedicated fixture. The chamber then heats or cools until the specified temperature is reached.
