塑料增材制造 环境、健康和安全 桌面材料挤出 3D 打印机颗粒和化学物质排放率测定的测试方法

[中文适用范围]： 本文件规定了在规定的测试条件下，在排放测试室中确定台式 MEX-TRB/P 工艺中经常用于非工业环境（如学校、家庭和办公室）的颗粒物排放（包括超细颗粒）和特定挥发性有机化合物（包括醛类）的测试方法。但是，这些测试不一定能准确预测真实世界的结果。本文件规定了一种使用排放测试室的调节方法，该测试室具有受控的温度、湿度、空气交换率、空气速度，以及用于监测、存储、分析、计算和报告排放率的程序。本文件旨在涵盖台式 MEX-TRB/P 机器，该机器通常适合放置在桌面上，用于非工业场所，如学校、家庭和办公室。本文件的主要目的是量化台式 MEX-TRB/P 机器的颗粒物和化学物质排放率。但是，这种方法并不涵盖所有可能的排放。许多原料可能会释放出本文件规定的化学检测器无法测量的有害排放物。用户有责任了解被挤压的材料和潜在的化学排放。一个例子是聚氯乙烯原料可能会排放氯化化合物，而该化合物无法通过本文件中描述的方法进行测量。 [外文原描述]： This document specifies test methods to determine particle emissions (including ultrafine particles) and specified volatile organic compounds (including aldehydes) from desktop MEX-TRB/P processes often used in non-industrial environments such as school, homes and office spaces in an emission test chamber under specified test conditions. However, these tests do not necessarily accurately predict real-world results. This document specifies a conditioning method using an emission test chamber with controlled temperature, humidity, air exchange rate, air velocity, and procedures for monitoring, storage, analysis, calculation, and reporting of emission rates. This document is intended to cover desktop MEX-TRB/P machine which is typically sized for placement on a desktop, used in non-industrial places like school, home and office space. The primary purpose of this document is to quantify particle and chemical emission rates from desktop MEX-TRB/P machine. However, not all possible emissions are covered by this method. Many feedstocks can release hazardous emissions that are not measured by the chemical detectors prescribed in this document. It is the responsibility of the user to understand the material being extruded and the potential chemical emissions. An example is Poly Vinyl Chloride feedstocks that can potentially emit chlorinated compounds, which cannot be measured by the method described in this document.
