This report is a test report issued by SGS, with Report No.: AJF52304002391FF, and the test date is APR.20, 2023.

1. 样品描述 (Sample Description)

样品名称 (Sample Description): 聚酯纤维吸音板 (Polyester Fiber Acoustic Panel)
颜色 (Color): 黑色 (Black)
密度 (Density): 1.9千克/平方米 (1.9kg/m2)
厚度 (Thickness): 9毫米 (9mm)
暴露面 (Exposed face): 正面 (Front surface)
安装方法 (Mounting methods): 样品通过条形夹具以约610毫米的间隔固定在隧道炉内部边缘上。测试样品由6块600毫米宽、1200毫米长、9.0毫米厚的板材组成，所有接缝都进行了端对端连接。
The sample was mounted using bars at intervals of approximately 610mm on the inner ledges of the tunnel for support. The specimen consisted of 6 pieces of 600mm wide by 1200mm long by 9.0mm thick, all sections joined end-to-end.

2. 测试请求与目的 (Test Requested and Purpose)

测试请求 (Test Requested): 参照 ASTM E84-2022 标准测试方法，用于建筑材料的表面燃烧特性测试 (ASTM E84-2022 Standard Test Method for Surface Burning Characteristics of Building Materials)。
测试目的 (Purpose of the test method): 该测试方法的目的是通过观察样品沿火焰蔓延的相对燃烧行为和烟雾蔓延指数（SDI）来确定材料的相对表面燃烧行为。
The purpose of this test method is to determine the relative surface burning behavior of materials by observing the flame spread along the specimen and smoke developed index (SDI).

3. 测试程序概述 (Overview of Test Procedure)

设备 (Equipment): 隧道预热至 65.6°C (150°F)，炉内末端热电偶测量值距燃烧器下方7.09米 (23.25英尺)，从燃烧器下方冷却至 40.6°C (105°F)。
**The tunnel was preheated to 65.6°C (150°F), as measured by the floor-embedded thermocouple located 7.09m (23.25 ft) downstream of the burner ports, and allowed to cool to 40.6°C (105°F).
样品放置 (Sample Placement): 样品沿隧道长度方向放置3.96米 (13英尺)。隧道顶部有一个连续的火焰槽，长7.32米 (24英尺)，位于盖子上方304.8毫米 (12英寸)。
The test sample is placed along the ledges of the tunnel so as to form a continuous ceiling 7.32m (24 ft) long, 304.8mm (12 in) above the lid.
火焰蔓延测量 (Flame Spread Measurement): 点燃燃气燃烧器后，火焰蔓延距离每30秒观察并记录一次。火焰蔓延距离与时间的关系曲线用于确定火焰蔓延指数（FSI）。
Upon ignition of the gas burners, the flame spread distance is observed and recorded every 30 seconds. Flame spread distance versus time is plotted to identify any flame front recessions. If the area under the curve (A) is less than or equal to 57.5 ft-min, FSI = 0.515 A; if greater, FSI = 4900(195-A).
烟雾蔓延指数测量 (Smoke-Developed Index Measurement): 烟雾蔓延指数（SDI）的测试结果通过绘制样品和庚烷的曲线下面积来计算。
The test results for smoke shall be plotted and the area under the curve shall be divided by the area under the curve for heptane, multiplied by 100, and rounded to the nearest multiple of five to establish a numerical smoke-developed index (SDI).
调节 (Conditioning): 测试前，样品在 23±2.8°C (73.4±5°F) 的恒定温度和 50±5% 的相对湿度下进行调节。
**Prior to testing, the sample was conditioned to a constant weight at a temperature of 23±2.8°C (73.4±5°F) and at a relative humidity of 50±5%.

4. 测试结果 (Test Results)

火焰蔓延指数 (Flame Spread Index, FSI): 0
烟雾蔓延指数 (Smoke-developed Index, SDI): 10

5. 评级与分类 (Rating and Classification) 根据国家消防协会生命安全规范第101章第10节10.2.3条《室内墙壁和天花板饰面分类》以及国际建筑规范第8章《室内饰面》第803条《墙壁和天花板饰面》的分类，测试结果如下：

A级 (Class A): 火焰蔓延指数 0-25，烟雾蔓延指数 0-450
B级 (Class B): 火焰蔓延指数 26-75，烟雾蔓延指数 0-450
C级 (Class C): 火焰蔓延指数 76-200，烟雾蔓延指数 0-450 Based on The National Fire Protection Association Life Safety Code 101, Chapter 10, Section 10.2.3 Interior Wall and Ceiling Finish Classification, and International Building Code, Chapter 8, Interior Finishes, Section 803 Wall and Ceiling Finishes, the classifications are as follows:
Class A: Flame Spread Index 0-25, Smoke-developed Index 0-450
Class B: Flame Spread Index 26-75, Smoke-developed Index 0-450
Class C: Flame Spread Index 76-200, Smoke-developed Index 0-450

结论 (Conclusion): 鉴于测试样品获得的火焰蔓延指数为0和烟雾蔓延指数为10，该样品符合A级室内墙壁和天花板饰面类别的要求。 Since the tested sample received a Flame Spread Index 0 and a Smoke-developed Index 10, it meets the requirements of Class A interior Wall & Ceiling Finish Category.

6. 观察结果 (Observations)

点燃时间 (Time to ignition): 33秒 (33 seconds)
达到最大火焰蔓延时间 (Time to Max. FS (sec)): 不适用 (Not applicable)
最大火焰蔓延距离 (Maximum FS (feet)): 0英尺 (0 feet)
其他观察 (Observations): 火焰滴落 (Flaming Dripping)

7. 警告 (Warning) 报告中包含一项重要警告：

在测试样品上使用的支撑材料可能会降低其火焰蔓延指数，这可能不代表在没有此类支撑的情况下测试材料所获得的指数。
当材料熔化、滴落或分层程度使得火焰前沿的连续性被破坏时，测试结果会导致低火焰蔓延指数，这些指数与测试保持原样的材料所获得的指数不直接相关。
测试结果仅与所测试的样品有关。组成或厚度的微小差异可能会显著影响产品的性能，因此必须确保所使用的产品与测试样品完全一致。
The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support.
Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place.
The test results relate only to the specimens of the product in the form in which were tested. Small differences in the composition or thickness of the product may significantly affect the performance during the test and may therefore invalidate the test results. Care should be taken to ensure that any product, which is supplied or used, is fully represented by the specimens, which were tested.

8. 照片附录 (Photo Appendix) 报告的最后一页提供了测试样品的照片。 The last page of the report includes a photo appendix showing the sample.

这份SGS报告详细说明了聚酯纤维吸音板在模拟火灾条件下的表面燃烧特性。该样品表现出优异的防火性能，火焰蔓延指数为0，烟雾蔓延指数为10，达到了严苛的A级标准，这意味着它在火灾发生时具有很低的火焰蔓延速度和烟雾产生量。然而，报告也明确指出，在解释这些结果时需注意支撑材料和样品特性的潜在影响。

In summary, this SGS report details the surface burning characteristics of the Polyester Fiber Acoustic Panel under simulated fire conditions. The sample demonstrated excellent fire performance, with a Flame Spread Index of 0 and a Smoke-Developed Index of 10, achieving the stringent Class A standard. This indicates that it has a very low flame spread rate and smoke production in the event of a fire. However, the report also clearly states that potential influences from supporting materials and sample characteristics must be considered when interpreting these results.
