常见问题  

Q1、贵司代理的各种试验粉尘通常使用在哪些检测标准中?

  我司代理的美国PTI试验粉尘应用在包括滤清器行业,电子行业等;德国DMT试验粉尘对于房屋通风系统过滤器应用比较广泛;而日本JIS试验粉尘的也应用在滤清器行业和电子行业;下表列出了来自美国PTI公司官方网站的常用的滤清器行业检测标准;

  自从我司2007年七月取得美国PTI公司中国独家代理权后。我们发现大部分客户并非来自滤清器行业,如果您已购买过我司代理的各种试验杂质,并愿意共享你们的标准,非常欢迎您来信联系我们,提供您使用的标准号,标准名称,对应的试验杂质以及简单的注释。我们将不断地扩充下表;

  共享是件很棒的事!

Q2、PTI公司的ISO等级的试验粉尘的密度(单位体积重量)大概是多少?

  1、 ISO 12103-1 A1 Ultrafine – 500 kg/m3
  2、 ISO 12103-1 A2 Fine – 900 kg/m3
  3、 ISO 12103-1 A3 Medium – 1025 kg/m3
  4、 ISO 12103-1 A4 Coarse – 1200 kg/m3
Q3、请问 SAE Fine Test dust 是否等同于 ISO 12103-1 A2 Fine Test Dust? SAE J726 试验粉尘和 ISO 12103-1 A2 Fine试验粉尘之间有何区别?

  ISO 12103-1, A2 细试验粉尘与1993年之前PTI公司生产的 SAE Fine Test Dust 是相同的。只是由于鉴于依据 ISO 12103-1 标准的测量仪器的升级,其报告的颗粒尺寸要略小一点点。 SAE J726 标准已在2002年作为并由 ISO 5011 取代,ISO 5011 指定使用满足 ISO 12103-1 标准的试验粉尘。关于这个问题的详细信息,点击此处访问试验粉尘的历史。

Q4、贵司提供的美国PTI粉尘在过滤行业中的应用表格很有帮助,能否对于德国DMT粉尘的应用也提供类似的表格呢?(2008-11)

Q5、ASHRAE和ANSI是什么意思?

  ASHRAEAmerican Society of Heating Refrigerating and Airconditioning Engineers 的缩写,意
       思是美国采暖, 制冷与空调工程师学会;
  ANSI 是 American National Standards Institute 的缩写,意思是美国国家标准协会;

Q6、同样尺寸塑料瓶装的ISO 12103-1 A2 Fine试验粉尘的重量为何比ISO 12103-1 A4轻约一公斤?按理说A2粉尘含有更多小颗粒,那应该重量更重才对啊?为何实际情况正好相反?

  ISO 12103-1 A2 Fine Test Dust 的确是含有更多的小颗粒,同样容积的塑料瓶内A2的试验粉尘颗粒数目也相对于ISO 12103-1 A4 Coarse Test Dust 更多。

  但是,较大尺寸的粉尘颗粒本身的重量较之小颗粒要更重,虽然A4粉尘的数量不及A2多,但重量却更重;另外,每个单独的粉尘颗粒之间会有空气存在,因此越多颗粒,也就意味着越多的空气,这样的后果就是较低的容重。比如一加仑罐子装0-3微米亚利桑那道路试验粉尘,其重量大概只有1.5公斤,而同样罐子装ISO粗灰,则重达4.5公斤。
