Descrizione del prodotto

YY-121 Building Materials Difficult Flammability Test Equipment

The YY-121 Building Materials Difficult Flammability Test Apparatus is designed for flame retardant performance testing of building materials. This computer-controlled equipment offers high automation for accurate fire resistance performance evaluation.

Compliance Standards

GB/T 8625 Test method of difficult-flammability for building materials
DIN 4102-15 Fire behavior of building materials and elements Brandschach

Key Features

Complete burning shaft furnace system including combustion chamber, burner, specimen support, air current stabilizer, and flue
Computer-controlled operation for precise furnace temperature and pressure management
High degree of automation for consistent test results

Working Principle

The testing process begins with four conditioned specimens vertically fixed on the test bracket, forming a vertical square flue. The specimens are positioned at (250±2) mm intervals. A uniform airflow is created in the combustion chamber through a 200mm diameter pipeline, maintaining a constant rate of (10±1) m³/min at controlled temperature.

Gas flow is adjusted to (35±0.5) L/min and air flow to (17.5±0.2) L/min before automatic ignition. The 10-minute test concludes when either the average flue gas temperature exceeds 200°C across five thermocouples or the maximum measured value surpasses 200°C.
