Gas analysis - Requirements for certificates for calibration gases and gas mixtures (ISO 6141:2000)
Specifies requirements for certificates for pure gases and for homogeneous gas mixtures to be used as calibration gases. Specifies the minimum information (mandatory data) required and additional information (optional data) recommended for characterizing a pure gas, or a homogeneous gas mixture, supplied under pressure in a cylinder or other container.
Gasanalyse - Anforderungen an Zertifikate für Kalibriergases und Kalibriergasgemische (ISO 6141:2000)
Diese Internationale Norm legt Anforderungen an Zertifikate für reine Gase und an Zertifikate für homogene Gasgemische fest, die als Kalibriergase verwendet werden sollen.
Diese Internationale Norm legt die mindestens erforderlichen Informationen (vorgeschriebene Angaben) und zusätzlich empfohlene Informationen (freiwillige Angaben) zur Kennzeichnung reiner Gase oder homogener Gasgemische fest, die unter Druck in Druckgasflaschen oder anderen Behältern geliefert werden. Diese Internationale Norm enthält keine Festlegungen zu sicherheitstechnischen Angaben und diesbezüglicher Kennzeichnung.
Für die in dieser Internationalen Norm festgelegten Informationen werden zwei verschiedene Formate behandelt:
- ein Zertifikat, d. h. ein dem Behälter eindeutig zugeordnetes Dokument, und
ein Zertifikatsauszug, d. h. ein am Behälter befestigtes Dokument.

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 com-
mittees. 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 liai-
son with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 6141 was prepared by Technical Committee ISO/TC 158, Analysis of gases.
This third edition cancels and replaces the second edition (ISO 6141:1984), which has been technically revised.

INTERNATIONAL STANDARD ISO 6141:2000(E)
Gas analysis — Requirements for certificates for calibration gases
and gas mixtures
1 Scope
This International Standard specifies requirements for certificates for pure gases and for certificates for homogene-
ous gas mixtures to be used as calibration gases.
This International Standard specifies the minimum information (mandatory data) required and additional information
(optional data) recommended for characterizing a pure gas, or a homogeneous gas mixture, supplied under pressure
in a cylinder or other container. This International Standard does not cover the field of safety-relevant data and re-
lated labelling.
Two different formats are considered for the information specified by this International Standard:
— a certificate, i.e., a document uniquely related to the container; and
— a certificate extract, i.e., a document affixed to the container.
2 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1
supplier
organization that has supplied the gas or gas mixture
2.2
customer
organization that has ordered the gas or gas mixture
2.3
container
vessel in which the gas or gas mixture is supplied
2.4
composition
property of a gas or a gas mixture given by the identity and the content of each specified component
2.5
component
chemical substance contained in the gas or gas mixture
2.6
specified component
component whose content is specified quantitatively in the certificate
NOTE In general, the content of the complementary gas is not specified explicitly.
2.7
impurity
component present, but not wanted
©
ISO 2000 – All rights reserved 1
ISO 6141:2000(E)
2.8
critical impurity
impurity affecting the intended use
2.9
complementary gas
component which completes the gas mixture
NOTE The complementary gas can be a pure gas or a gas mixture.
2.10
standard uncertainty
uncertainty of the content of a specified component, expressed as a standard deviation
NOTE 1 This definition is an adaptation of the definition given in GUM (see reference [1] in the Bibliography).
NOTE 2 The standard uncertainty can be expressed as an absolute value or as a relative value.
2.11
expanded uncertainty
uncertainty of the content of a specified component, expressed as a product of the standard uncertainty and a cov-
erage factor
NOTE 1 This definition is an adaptation of the definition given in GUM [1].
NOTE 2 The expanded uncertainty aims at characterizing a confidence interval at a confidence level of approximately 95 %.
3 Requirements for certificates and certificate extracts
3.1 General
The information specified by this International Standard shall be provided by the supplier of the gas or the gas mix-
ture, in two different formats:
— a certificate, i.e., a document uniquely related to the container; and
— a certificate extract, i.e., a document affixed to the container.
The certificate shall contain as a minimum the data specified as “mandatory” in Table 1. It is recommended that the
data specified as “optional” also be included in the certificate.
The certificate extract shall contain as a minimum the data specified as “mandatory” in Table 2. The certificate extract
shall be affixed to the container in a secure way, such as in the form of a sticker or tag.
NOTE Consideration should be given to protect the sticker or tag from adverse conditions of exposure.
Requirements for and explanations of the individual data are given in the following clauses. Those data in capital let-
ters, and the associated requirements, are mandatory. When optional data are adopted, then the associated require-
ments become mandatory.
