Demonstration of dependability requirements - The dependability case

IEC 62741:2015 gives guidance on the content and application of a dependability case and establishes general principles for the preparation of a dependability case. This standard is written in a basic project context where a customer orders a system that meets dependability requirements from a supplier and then manages the system until its retirement. The methods provided in this standard may be modified and adapted to other situations as needed. The dependability case is normally produced by the customer and supplier but can also be used and updated by other organizations. For example, certification bodies and regulators may examine the submitted case to support their decisions and users of the system may update/expand the case, particularly where they use the system for a different purpose. Keywords: dependability, reliability, availability, maintainability, supportability, usability, testability, durability.

Démonstration des exigences de sûreté de fonctionnement - Argumentaire dans le cadre de la sûreté de fonctionnement

L'IEC 62741:2015 fournit des lignes directrices concernant le contenu et l'application d'une étude de sûreté de fonctionnement et établit les principes généraux pour la préparation d'une étude de sûreté de fonctionnement. La présente norme est rédigée dans le cadre d'un projet de base où un client commande un système qui satisfait aux exigences de sûreté de fonctionnement d'un fournisseur et gère alors le système jusqu'à sa mise hors service. Les méthodes fournies dans cette norme peuvent être modifiées et adaptées aux autres situations, si nécessaire. L'étude de sûreté de fonctionnement est normalement produite par le client et le fournisseur et peut également être utilisée et mise à jour par d'autres organisations. Par exemple, les organismes de certification et législateurs peuvent examiner l'étude soumise pour étayer leurs décisions et les utilisateurs du système peuvent mettre à jour/développer l'étude, notamment lorsqu'ils utilisent le système à une autre fin. Mots clés: sûreté de fonctionnement, la fiabilité, la disponibilité, la maintenabilité, l'aptitude au soutien, l'utilisation, la testability, la durabilité.

Vodilo za predstavitev zahtev za zagotovljivost - Primer zagotovljivosti

Ta mednarodni standard nudi smernice glede vsebine in uporabe primera zagotovljivosti in vzpostavlja osnovne principe za pripravo primera zagotovljivosti. Ta standard je napisan v okviru osnovnega projekta, kjer stranka pri dobavitelju naroči sistem, ki ustreza zahtevam za zagotovljivost, in ga nato upravlja do konca življenjske dobe. Metodo, ki jo ta standard zagotavlja, se lahko po potrebi spremeni in prilagodi, da ustreza drugačnim situacijam. Primer zagotovljivosti navadno ustvarita stranka in dobavitelj, lahko pa ga uporabljajo in posodabljajo tudi druge organizacije. Na primer, certifikacijski in upravni organi lahko pregledajo dobljeni primer, da lahko podprejo svoje odločitve, uporabniki sistema pa lahko posodobijo/razširijo primer, posebej če uporabljajo sistem v drugačne namene.
