施泰纳隧道试验

施泰纳隧道试验s measure the surface burning characteristics of interior finish materials and assemblies used in buildings, which is critical to understanding how materials react during a fire. Using the ASTM E84, UL 723, 可以/ ULC-S102, and 可以/ ULC-S102.2 .测试程序, we can help you achieve safety and ensure compliance with building codes, 地方政府, 或者im体育平台app下载要求. 

These tests are designed to determine the relative ability of building interior finishes, 比如墙壁, 天花板, 和地板, to resist a moving flame front across their surface while at the same time limiting smoke production. 

The results provide comparative measurements of surface flame spread and smoke development of materials. Code officials and regulatory agencies can use them in the acceptance of interior finish materials for various applications. 

斯坦纳隧道试验程序

im体育APP's highly qualified materials experts provide the 施泰纳隧道试验 in accordance with the most frequently specified standard test methods for surface burning characteristics of building products in North America and the Middle East. The most common tests are ASTM E84, UL 723, 可以/ ULC-S102, and 可以/ ULC-S102.2. 

ASTM E 84 is procedurally similar to UL 723, and the two tests are often cited together as equivalent by many building codes and authorities. Materials are ceiling-mounted in the horizontal tunnel. 可以/ ULC-S102 is the Canadian version of 施泰纳隧道试验ing and is closest in similarity to ASTM E 84 and UL 723, also utilizing the ceiling-mounting method. 可以/ ULC-S102.2是落地式版本.

The testing can be utilized in the product development stage as part of on-going quality assurance programs or for compliance with building codes and jurisdictional requirements. 

Ceiling-mounted 施泰纳隧道试验: ASTM E84, UL 723, AND 可以/ ULC-S102

The test apparatus is a large-scale, horizontal furnace chamber into which a 24-feet long by 21-inch wide test specimen is inserted to form the ceiling of the tunnel, facing the floor of the apparatus.

在十分钟的测试中, materials are tested for flame spread when exposed to a large 气体 burner's direct flame impingement. Air and combustion products are moved through the tunnel by a ventilation system at a controlled velocity. The flame front's progress across the test material is measured by visual observation through windows built into the tunnel, while the smoke developed from the test assembly is measured downstream from the apparatus as a calculated product of photocell obscuration.

Floor-mounted 施泰纳隧道试验: 可以/ ULC-S102.2

For materials that are typically installed facing upward (i.e., flooring) or materials that melt and drip in a ceiling-mounted scenario, Canadian authorities require 可以/ ULC-S102.2 testing instead of 可以/ ULC-S102. The apparatus is configured in the same manner as 可以/ ULC-S102 testing. The notable exceptions of the specimen being mounted on the apparatus's floor and the test burner being re-positioned to point downward at the specimen. Similar values to the ceiling tests are recorded and are reported.
