This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 304, Quality

Standards, and the MSS Coordinating Committee. The content of this Standard Practice is the resulting efforts of

knowledgeable and experienced industry volunteers to provide an effective, clear, and non-exclusive standard that will

benefit the industry as a whole. This MSS Standard Practice describes minimal requirements and is intended as a basis

for common practice by the manufacturer, the user, and the industry at large. It is the responsibility of the user of this

Standard Practice to establish appropriate safety and health practices and determine the applicability of regulatory

requirements prior to use. The existence of an MSS Standard Practice does not in itself preclude the manufacture, sale,

or use of products not conforming to the Standard Practice. Mandatory conformance to this Standard Practice is

established only by reference in other documents such as a code, specification, sales contract, or public law, as

applicable. MSS has no power, nor does it undertake, to enforce or certify compliance with this document. Any

certification or other statement of compliance with the requirements of this Standard Practice shall not be attributable

to MSS and is solely the responsibility of the certifier or maker of the statement.

“Unless indicated otherwise within this MSS Standard Practice, other standards documents referenced to herein are

identified by the date of issue that was applicable to this Standard Practice at the date of approval of this MSS Standard

Practice (see Annex B). This Standard Practice shall remain silent on the validity of those other standards of prior or

subsequent dates of issue even though applicable provisions may not have changed.”

By publication of this Standard Practice, no position is taken with respect to the validity of any potential claim(s) or of any

patent rights in connection therewith. MSS shall not be held responsible for identifying any patent rights. Users are expressly

advised that determination of patent rights and the risk of infringement of such rights are entirely their responsibility.

For all MSS Standard Practices, the term “shall” means “must” and “shall not” means “must not”.

In this Standard Practice, all text, notes, annexes, tables, figures, and references are construed to be “normative” and essential

to understand the standard’s message. All appendices and footnotes, or any other information denoted as “supplemental”,

that may be included within this Standard Practice, DO NOT involve mandatory or normative requirements.

This Standard Practice has been substantially revised from the previous 2014 edition. It is suggested that if

the user is interested in knowing what changes have been made, that direct page by page comparison should

be made of this document and that of the previous edition.

Excerpts of this Standard Practice may be quoted with written permission. Credit lines should read ‘Extracted from MSS SP-
