This standard applies to all types of surface-mount fluid distribution components with elastomeric sealing devices used within process analyzer and sample-handling systems. This includes components such as valves, filters, regulators, transducers, and controllers.

The scope of this document is limited as follows:

a) This document addresses only surface-mount fluid distribution components and proper sealing methods. This document is limited to sealing methods using elastomeric material for the seals.

b) The designs of the actual system components and the flow substrate are not specified in this standard. Any indication of mounting direction or other indexing is left to the manufacturer as required for its equipment.

c) Users shall be aware that, based on the stream conditions of their processes, other technologies and components may be readily available.

d) This standard does not address the effects of various stream conditions on the technical functionality of the component.

e) This standard does not address maintenance concerns for the components.

f) This standard does not refer to design issues pertaining to specific safety requirements. These issues shall be referenced to other standards, organizations, and recommended guidelines.

g) International, national, and local codes, regulations, and laws shall be consulted to ensure that each component meets the user's regulatory requirements.

Purpose

This document establishes properties and physical dimensions that define the interface for surface-mount fluid distribution components with elastomeric sealing devices used within process analyzer and samplehandling systems. The interface controls the dimensions and location of the sealing surfaces to allow change of just one element of the system without modification of the entire system. This is what makes the system modular from both a design and a maintenance standpoint.
