UN3270 硝化纤维素膜过滤器，按干的重量，含氮不大于 12.6%

过滤器可为小的圆片状或大的 片状物。遇火时放出毒性烟 雾；在封闭舱室内，这种烟雾 与空气形成爆炸混合物。在强 烈的热辐射下，迅速燃烧。

Filters may be small round pieces or large sheets. When involved in a fire, evolve toxic fumes; in closed compartments, these fumes may form an explosive mixture with air. Burn rapidly with intense heat radiation.

运输中使用的膜滤器包括隔离纸、涂层或衬垫材料等，须按《试验和标准手册》第 I部分试验系列1(a)中任何一个试验证实不易于传播爆炸。 此外，主管当局可以依据《试验和标准手册》第 III部分33.2.1中燃烧速率试验测试结果，确定用于运输的这种形式的硝化纤维薄膜滤器不适用第4.1类易燃固体的规定。

The membrane filters, including paper separators, coating or backing materials, etc., that are present in transport, shall not be liable to propagate a detonation as tested by one of the tests described in the Manual of Tests and Criteria, part I, test series 1(a). In addition, the competent authority may determine, on the basis of the results of suitable burning rate tests taking account of the standard tests in the Manual of Tests and Criteria, part III, 33.2, that nitrocellulose membrane filters in the form in which they are to be transported are not subject to the provisions of this Code applicable to flammable solids in class 4.1.
