DIMENSIONAL SPECIFICATION FOR METRIC PFA TUBES FOR
LIQUID CHEMICAL DISTRIBUTION IN SEMICONDUCTOR AND FLAT
PANEL DISPLAY MANUFACTURING
This specification was technically approved by the Global Liquid Chemical Distribution Systems Committee
and is the direct responsibility of the Japanese Liquid Chemical Distribution Systems Committee. Current
edition approved by the Japanese Regional Standards Committee on June 19, 2001. Initially available on
www.semi.org August 2001; to be published November 2001. Originally published June 2000.
1 Purpose
1.1 This document defines sizes and their measurement
methods of metric PFA tubes for liquid chemical
distribution in semiconductor and flat panel display
manufacturing equipment and facilities.
2 Scope
2.1 This document applies to metric tubes made from
PFA.
2.2 This specification does not purport to address
safety issues, if any, associated with its use. It is the
responsibility of the users of this specification to
establish appropriate safety and health practices and
determine the applicability of regulatory limitations
prior to use.

5 Nominal Size and Dimensional Specification
5.1 A nominal tube size is indicated by “outside
diameters/inside diameter”. This document provides
specifications for eight nominal tube sizes as shown in
Table 1.
5.2 The indication of the nominal size for metric PFA
tubes is preferably printed on each package for
shipping.
