This Standard specifies minimum performance requirements for ultra high purity (UHP) polymer materials and components suitable for conveying ultrapure water (UPW) in UPW distribution systems. Further information regarding UPW systems can be found in SEMI F61, SEMI F63.

It also provides recommendations for the use of polymer materials and components used in UHP liquid chemical distribution systems (LCDS). Such distribution systems covered in this Specification include bulk supply, facility distribution, and process equipment applications.

Although the requirements of this Specification focus on testing materials and components with UPW at elevated temperatures, there could be other applicable chemicals, such as caustics and oxidizers, which users of this Specification might like to consider. However, defining the vast number of testing parameters for each possible liquid chemistry stream is beyond the scope of this Specification. Nevertheless, this Specification intends neither to exclude nor to limit the possibility that suppliers and end-users might test with chemicals other than UPW or with other temperature conditions and, at the same time, set their own internal limits separate from the requirements within this Specification.

This Specification focuses on polymer material and component performance and validation. Operational requirements to ensure polymer materials and components meet the intent of this Specification are provided where appropriate. A summary list follows:

  • Quantitative Measures of Compliance
  • Metallic Contribution Limits
  • Ionic Contribution Limits
  • Total Organic (Oxidizable) Carbon Contribution Limits
  • Surface Roughness Limits
  • Qualitative Measures of Compliance
  • Mechanical Properties
  • Physical Properties
  • Chemical Resistance
  • Reliability
  • Traceability Requirements
  • Packaging Requirements
  • Certification

This Specification pertains to polymer materials and components consisting of but not limited to the items shown in Table 1 are designed to contain and supply the following, but not limited to, the types of liquid chemicals listed below:

  • UPW
  • Acids, bases and oxidizers
  • Aqueous salt solutions
  • Solvents

Polymer materials and components that meet the requirements specified in this Standard shall be considered suitable for UPW and LCDS as described in ¶ 1.3. Refer to SEMI C90 for additional requirements for the use of polymers in LCDS.
