Tolerances for fasteners - Part 3: Washers for bolts, screws and nuts - Product grades A, C and F (ISO 4759-3:2016)

ISO 4759-3:2016 specifies tolerances for flat washers of product grades A, C and F with nominal diameters of 1 mm to 150 mm inclusive, designed to be used in bolted joints in combination with bolts, screws, studs and nuts.
This part of ISO 4759 may be applied to non-flat washers however it does not include all the tolerances related to these washers.
It applies to non-captive and captive washers, and to standard and non-standard washers.
It does not apply to dynamic disc springs.
Washers of product grades F and A are intended to be used with bolts, screws, studs and nuts of product grades A and B; washers of product grade C are intended to be used with bolts, screws, studs and nuts of product grade C.
NOTE          The product grade refers to a specific tolerance range related to dimensional and geometrical characteristics (product grade F for fine tolerances, product grade A for precise tolerances, product grade C for large tolerances).
Annex A presents tolerances taken from ISO 286‑1 and ISO 286‑2.

Toleranzen für Verbindungselemente - Teil 3: Scheiben für Schrauben und Muttern - Produktklassen A, C und F (ISO 4759-3:2016)

Dieser Teil von ISO 4759 legt Toleranzen für flache Scheiben der Produktklassen A, C und F mit Nenn-durchmessern von 1 mm bis einschließlich 150 mm fest, die für die Verwendung in Schraubverbindungen in Kombination mit Schrauben und Muttern vorgesehen sind.
Diese Norm darf auch auf nicht-flache Scheiben angewendet werden, für die jedoch nicht alle Toleranzen erfasst werden.
Sie gilt sowohl für verlierbare als auch für unverlierbare Scheiben sowie für genormte und für nicht genormte Scheiben.
Sie gilt nicht für dynamisch beanspruchte Tellerfedern.
Scheiben der Produktklassen F und A sind für die Anwendung mit Schrauben und Muttern der Produktklassen A und B vorgesehen; Scheiben der Produktklasse C sind für die Anwendung mit Schrauben und Muttern der Produktklasse C vorgesehen.
ANMERKUNG   Die Produktklasse bezieht sich auf einen spezifischen Toleranzbereich bezogen auf maßliche und geo¬metrische Merkmale.
Der informative Anhang A enthält Toleranzen aus ISO 286 1 und ISO 286 2.

Tolérances pour fixations - Partie 3: Rondelles pour vis et écrous - Grades A, C et F (ISO 4759-3:2016)

ISO 4759-3:2016 spécifie les tolérances pour les rondelles de forme plane de grades A, C et F de diamètre nominal de 1 mm à 150 mm inclus, conçues pour être utilisées dans des assemblages boulonnés en combinaison avec des vis, goujons, tiges filetées et écrous.
ISO 4759-3:2016 peut être appliquée aux rondelles de forme non plane cependant, elle ne comporte pas toutes les tolérances liées à ces rondelles.
Elle s'applique aux rondelles libres et aux rondelles imperdables, normalisées et non normalisées.
Elle ne s'applique pas aux rondelles ressorts dynamiques (dites « Belleville »).
Les rondelles de grades F et A sont destinées à être utilisées avec des vis, goujons, tiges filetées et écrous de grades A et B, les rondelles de grade  C sont destinées à être utilisées avec des vis, goujons, tiges filetées et écrous de grade C.
NOTE          Le grade correspond à une gamme de tolérances spécifiques relatives aux caractéristiques dimensionnelles et géométriques (grade F pour les tolérances fines, grade A pour les tolérances précises, grade C pour les tolérances larges).
L'Annexe A présente les tolérances issues de l'ISO 286‑1 et l'ISO 286‑2.

Tolerance za mehanske vezne elemente - 3. del: Ravne podložke za vijake in matice - Razredi izdelave A, C in F (ISO 4759-3:2016)

Ta del standarda ISO 4759 določa tolerance za ravne podložke razredov izdelave A, C in F z nominalnim
premerom od 1 mm do vključno 150 mm, ki so zasnovane za uporabo v vijačnih zvezah skupaj z vijaki
in maticami.
Ta del standarda ISO 4759 se lahko uporablja za neravne podložke, vendar ne vključuje vseh toleranc, povezanih s takšnimi podložkami.
Uporablja se za nerobljene in robljene podložke ter standardne in nestandardne podložke.
Ne uporablja se za dinamične diskaste vzmeti.
Podložke razredov izdelave F in A so namenjene za uporabo z vijaki in maticami razredov A in B; podložke razreda izdelave C so namenjene za uporabo z vijaki in maticami razreda izdelave C.
OPOMBA: razred izdelave se nanaša na določen tolerančni obseg, povezan z dimenzijskimi in geometrijskimi
značilnostmi (razred izdelave F za ozke tolerance, razred izdelave A za natančne tolerance, razred izdelave C za velike tolerance).
V Dodatku A so predstavljene tolerance iz standardov ISO 286-1 in ISO 286-2.

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 WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

The committee responsible for this document is ISO/TC 2, Fasteners.

This fourth edition cancels and replaces the third edition (ISO 4759-3:2000), which has been technically

a) the scope has been amended;
b) the normative references have been updated;
c) a new Clause 3 “Symbols and abbreviated terms” has been added;
d) new product grade F has been included (F for Fine tolerances);
e) tolerances for chamfers have been included;

f) in Table A.1 tolerances for standard tolerance grades IT11 and IT14 have been included and IT16

has been deleted;

g) in Tables A.2 and A.3 limit deviations for tolerance classes h13 and H12 respectively have been

included;
h) the bibliography has been updated;
i) this part of ISO 4759 has been editorially revised.

ISO 4759 consists of the following parts, under the general title Tolerances for fasteners:

— Part 1: Bolts, screws, studs and nuts — Product grades A, B and C
— Part 3: Washers for bolts, screws and nuts — Product grades A, C and F
