Transfusion equipment for medical use - Part 3: Blood-taking sets for single use (ISO 1135-3:2016)

ISO 1135-3:2016 specifies requirements for types of blood-taking sets for medical use in order to ensure functional interchangeability of transfusion equipment. It is applicable to sterilized blood-taking sets intended for single use only.
ISO 1135-3:2016 also aims to provide
a) specifications relating to the quality and performance of materials used in transfusion equipment, and
b) a unified presentation of terms for such equipment.
In some countries, the national pharmacopoeia or other national regulations are legally binding and take precedence over ISO 1135-3:2016.

Transfusionsgeräte zur medizinischen Verwendung - Teil 3: Blutentnahmegeräte zur einmaligen Verwendung (ISO 1135-3:2016)

Dieser Teil von ISO 1135 legt Anforderungen an Blutentnahmegeräte für die medizinische Verwendung fest, um die funktionelle Austauschbarkeit von Transfusionsgeräten sicherzustellen. Sie ist auf sterilisierte Blutentnahmegeräte zur einmaligen Verwendung anzuwenden.
Dieser Teil von ISO 1135 stellt auch zur Verfügung:
a)   Qualitätsanforderungen für die in Blutentnahmegeräten verwendeten Werkstoffe, und
b)   eine einheitliche Darstellung von Benennungen für Blutentnahmegeräte
festzulegen.
In einigen Ländern sind das nationale Arzneibuch oder andere nationale Bestimmungen rechtlich bindend und haben Vorrang vor diesem Teil von ISO 1135.

Matériel de transfusion à usage médical - Partie 3: Appareils non réutilisables pour prélèvement sanguin (ISO 1135-3:2016)

ISO 1135-3:2016 fixe les spécifications des divers types d'appareils pour prélèvement sanguin à usage médical afin d'assurer I'interchangeabilité fonctionnelle du matériel de transfusion. Elle s'applique aux appareils stériles non réutilisables pour prélèvement sanguin.
ISO 1135-3:2016 a également pour but de fournir
a) des spécifications relatives à la qualité et aux performances des matériaux utilisés pour le matériel de transfusion; et
b) une terminologie uniforme concernant ce type de matériel.
Dans certains pays, la pharmacopée nationale ou d'autres règlements nationaux sont juridiquement contraignants et prévalent sur les dispositions de l'ISO 1135-3:2016.

Transfuzijska oprema za uporabo v medicini - 3. del: Seti za odvzem krvi za enkratno uporabo (ISO 1135-3:2016)

Ta del standarda EN ISO 1135 določa zahteve za vrste setov za odvzem krvi za uporabo v medicini, da se zagotovi funkcijska zamenljivost opreme za transfuzijo. Uporablja se samo za sterilizirane sete za odvzem krvi za enkratno uporabo. Materiali in sestavni deli setov so validirani na podlagi različnih preskusnih metod. Proizvajalec izbere ustrezne preskusne metode za uskladitev z zahtevami, določenimi v tem delu standarda EN ISO 1135. Druga cilja tega dela standarda EN ISO 1135 sta zagotoviti a) specifikacije glede kakovosti in učinkovitosti materialov, ki se uporabljajo v opremi za transfuzijo; b) enotno predstavitev pogojev in označb za takšno opremo. V nekaterih državah so nacionalne farmakopeje ali drugi nacionalni predpisi pravno zavezujoči in imajo prednost pred tem delom standarda EN ISO 1135.

Annex ZA
(informative)
Relationship between this European standard and the essential
requirements of Directive 93/42/EEC [OJ L 169] aimed to be covered

This European Standard has been prepared under a Commission's standardization request ‘M/295

concerning the development of European standards related to medical devices’ to provide a voluntary

means of conforming to essential requirements of Council Directive 93/42/EEC of 14 June 1993

concerning medical devices [OJ L 169].

Once this standard is cited in the Official Journal of the European Union under that Directive,

compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of

the scope of this standard, a presumption of conformity with the corresponding essential requirements

of that Directive, and associated EFTA regulations.

NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk

management process needs to be in compliance with Directive 93/42/EEC as amended by 2007/47/EC. This

means that risks have to be reduced "as far as possible", "to a minimum", "to the lowest possible level",

"minimized" or "removed", according to the wording of the corresponding essential requirement.

NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with Essential

Requirements 1, 2, 5, 6, 7, 8, 9, 11 and 12 of the Directive.

NOTE 3 This Annex ZA is based on normative references according to Table 1 of references in the European

foreword, replacing the references in the core text.

NOTE 4 When an Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this

European Standard.

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

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the

Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.

The committee responsible for this document is ISO/TC 76, Transfusion, infusion and injection, and blood

processing equipment for medical and pharmaceutical use.

This second edition cancels and replaces the first edition (ISO 1135-3:1986), which has been technically

revised with the following changes:

— part title has been amended by “for single use” in alignment with the other parts of ISO 1135;

— figures have been updated;
— subclause 3.6, “Designation examples” has been deleted;

— physical, chemical and biological requirements have been aligned with ISO 1135-4;

— Clause 10, “Disposal” has been added;
— Annexes A, B and C have been aligned with ISO 1135-4;
— all references have been updated.

ISO 1135 consists of the following parts, under the general title Transfusion equipment for medical use:

— Part 3: Blood-taking sets for single use
— Part 4: Transfusion sets for single use, gravity feed
— Part 5: Transfusion sets for single use with pressure infusion apparatus

Transfusion equipment for medical use —
Part 3:
Blood-taking sets for single use
1 Scope

This part of ISO 1135 specifies requirements for types of blood-taking sets for medical use in order

to ensure functional interchangeability of transfusion equipment. It is applicable to sterilized blood-

taking sets intended for single use only.
This part of ISO 1135 also aims to provide

a) specifications relating to the quality and performance of materials used in transfusion

equipment, and
b) a unified presentation of terms for such equipment.

In some countries, the national pharmacopoeia or other national regulations are legally binding and

take precedence over this part of ISO 1135.
