Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

It is essential to detect argon in powder metallurgy hot isostatic pressing (PM HIP) material in order to

ensure the desired performance of the PM HIP component. Argon from the production of powder can

remain in the powder grains. Argon from the powder filling processes can remain in the voids between

powder grains and become trapped during consolidation. Can imperfections can result in ingress of

argon from the HIP chamber and potentially introduce, or increase the level of, argon.

Argon in the resulting metal powder produced component can be detected using the techniques

included in this document

IMPORTANT — It is the responsibility of the purchaser of the PM HIP service to specify in

the purchase order if an argon detection test is needed. If so, the agreed argon limit shall be

specified.
1 Scope

This document specifies a gas chromatography and a mass spectrometry method of detecting the

presence of argon in metal powder produced components, consolidated by hot isostatic pressing.

This document specifies the calibration and functionality test for the equipment covered. It also

specifies methods for sampling, sample preparation and sample test procedure of PM HIP components

to detect argon presence.
Components produced by additive manufacturing are not covered in this document.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
blank test

test performed without sample in the same manner as, and parallel with, a test using an analytical

sample
[SOURCE: ISO 11323:2010, 8.13]
3.2
calibration

operation that, under specified conditions, in a first step, establishes a relation between the quantity

values with measurement uncertainties provided by measurement standards and corresponding

indications with associated measurement uncertainties and, in a second step, uses this information to

establish a relation for obtaining a measurement result from an indication

Note 1 to entry: A calibration may be expressed by a statement, calibration function, calibration diagram,

calibration curve, or calibration table. In some cases, it may consist of an additive or multiplicative correction of

the indication with associated measurement uncertainty.

Note 2 to entry: Calibration should not be confused with adjustment of a measuring system, often mistakenly

called “self-calibration”, nor with verification of calibration

Note 3 to entry: Often, the first step alone in the above definition is perceived as being calibration.
