Building Materials Ignitability Tester

1.Scope of Application:

This apparatus is suitable for testing the ignitability of materials, composite materials, or assemblies with a thickness not exceeding 70 mm when placed horizontally and exposed to specified thermal radiation conditions.

It can be used to evaluate wall and ceiling lining materials, flooring systems, external claddings, and insulation materials for air-heating ducts. Under specific fire scenarios, the test accurately describes the fire exposure behavior of products. Therefore, the results reflect the combustion performance of products in actual use.

Through testing, materials that are easily ignited and those that are difficult to ignite can be distinguished, helping to classify the fire hazard level of materials.

2. Complies with Standards:

2.1 GB/T 14523-2007 Test Method for Ignitability of Building Materials

2.2 ISO 5657:1997 Reaction to Fire Tests — Ignitability of Building Products

Main Performance Parameters:

Complete unit: Composed of a radiation cone, ignition device, nozzle, pressing plate mechanism and support frame, temperature recorder, gas system, signal acquisition and processing system, computer, etc.

Multi-functional Friction and Wear Testing Machine

This equipment features two motion modes, including rotational and  reciprocating test modules, which can be easily replaced to meet a wider range  of testing requirements.

(1) Rotational Module

The equipment operates in a rotational mode to realize various friction  contact forms and lubrication conditions. It is used to simulate friction tests  between different tribological pairs, with multiple configurations such as  pin-on-disc, end-face friction pair, and ball-on-disc friction pair. It can  perform point, line, and surface friction simulation tests.

It is suitable for evaluating the friction and wear performance of materials  such as lubricants, metals, coatings, surface coatings, plastics, rubber, and  ceramics. It meets the requirements of users in petroleum and chemical industry,  machinery, energy, metallurgy, aerospace, and other tribology-related fields for  the development and testing of high-end oil and grease products, as well as new  material development and process research.

(2) Reciprocating Module

The equipment operates in reciprocating mode, mainly used for friction and  wear performance testing of materials and surface coatings.

It adopts an industrial control computer system for real-time monitoring and  control of the entire test process. The test force is automatically maintained  with constant loading and supports dynamic variable loading (sine wave, triangle  wave, square wave, trapezoidal wave), ensuring stable and reliable loading.

It can simulate point, line, and surface contact friction forms under  reciprocating motion, enabling measurement of friction force, wear volume, and  other parameters under different loads, frequencies, lubrication conditions, and  temperatures.

The system can be expanded with corrosion resistance functionality to  simulate testing under deep-sea environmental conditions.
