Overview

EN 1515-1:1999 is a European Standard developed by CEN that provides comprehensive guidelines for the selection of bolting in flange joints. This standard applies specifically to bolting used with PN designated flanges according to the EN 1092 series and Class designated flanges in the EN 1759 series. The document defines the essential criteria for dimensions, material properties, and delivery conditions of bolts, stud bolts, and nuts utilized in flange connections.

By standardizing the selection process of bolting, EN 1515-1 ensures reliable, safe, and effective flange joints across various industrial sectors. While the standard focuses on flange-specific bolting applications, it is not designed for general-purpose bolting selection.

Key Topics

  • Scope of Bolting Selection: Covers bolts, stud bolts, and nuts specifically for use with EN 1092 and EN 1759 flange types.
  • Material Specifications: Details on commonly used materials suitable for all pressure and temperature ranges encountered in standard flange service conditions.
  • Dimensional Standards: Defines the technical dimensions required to maintain consistency and compatibility with designated flanges.
  • Technical Delivery Conditions: Specifies requirements for manufacturing, testing, and quality assurance to ensure bolting performance.
  • Pressure and Temperature Ratings: Addresses the selection of bolting materials and types that can withstand various operational environments related to pressure and temperature.
  • Exclusions: Clarifies that this standard is tailored only for flange-specific bolting and should not be used for general bolting applications.

Applications

EN 1515-1:1999 is essential for industries that rely on secure and standardized flange connections, including:

  • Oil and Gas: Pipelines, pressure vessels, and processing equipment requiring reliable bolted flange joints under high pressure and temperature.
  • Chemical and Petrochemical: Corrosion-resistant and temperature-tolerant bolting for chemical processing equipment.
  • Power Generation: Steam and gas turbines, heat exchangers, and boilers where flange integrity is critical.
  • Water and Wastewater Treatment: Durable bolted connections in piping systems operating under varied pressure conditions.
  • Mechanical Engineering: Equipment assembly involving pressure-rated flange joints requiring precise bolting selection.

The standard supports engineers, designers, and maintenance professionals in choosing the right bolting solutions that comply with European flange standards, enhancing system safety and longevity.

Related Standards

For comprehensive flange and bolting system management, EN 1515-1 should be used alongside:

  • EN 1092 Series: Specifications for PN-designated flanges, providing detailed structural and material guidelines.
  • EN 1759 Series: Covers Class-designated flanges for enhanced performance applications.
  • EN 1515-2 (if applicable): Addresses bolting assembly and maintenance practices.
  • ISO 898-1: International standard for mechanical properties of bolts and nuts.
  • EN ISO 3506 Series: Stainless steel fasteners standards, relevant when selecting corrosion-resistant materials.

Integrating EN 1515-1 with related standards ensures a holistic approach to flange and joint design, installation, and maintenance.

By following EN 1515-1:1999, organizations can guarantee the selection of appropriate bolting crucial for the safety, effectiveness, and compliance of flange joints in numerous industrial applications. This standard enhances operational reliability and reduces the risk associated with flange joint failures.

Safety of toys - Part 20: Microbiological safety of toys containing accessible aqueous media
kSIST FprEN 71-20:2025

This document specifies microbiological cleanliness and preservative efficacy requirements for accessible aqueous media in toys.
The requirements in this document apply to all toys that are, contain or are supplied with accessible aqueous materials (e.g. paste, putty, finger paint, liquid or gel).
The cleanliness and preservation effectiveness requirements are applicable to a toy as it is initially received by the consumer, in an unopened and undamaged container. This document does not apply to a toy that has been used, has had its packaging opened or is otherwise compromised in a way that would introduce microbiological contamination.
This document does not apply to toys and samples which are post-consumer use, since the microbiological limits are inappropriate given, there is no way to establish what conditions the toys have been subject to before testing.
This document does not apply to:
-   materials that are inaccessible during normal use or after reasonably foreseeable abuse;
-   food;
-   cosmetics;
-   components of toys covered by EN 71-13 where;
-   the component is in scope of the Cosmetic Products Regulation (i.e. Regulation (EC) No 1223/2009 [13];
-   the component comprises only recognized food flavours and food ingredients (see relevant legislation, for example Regulation (EC) No 178/2002 [16] ("general food law"), Regulation (EC) No 1334/2008 [15] (flavours), Regulation (EC) No 1333/2008 [14], Commission Regulation (EU) No 231/2012 [18] (food additives) and Regulation (EU) No 1169/2011 (food information to consumers)[17]);
-   experimental sets covered by EN 71-4.
NOTE   Play cosmetics, that are only for use on the toy (e.g. makeup products only for a doll), are not excluded.

Aerospace series - Programme management - Recommendations for the implementation of the integrated logistic support
kSIST FprEN 9276:2025

The purpose of this document is to:
—   identify and describe, in a structured way, the principles of the integrated logistic support (ILS) activities and tasks for the main types of stakeholders in the system life cycle, from the expression of need to disposal;
—   place the activities, tasks and ILS deliverables within the programme execution;
—   identify the main selection and sizing of activities and tasks criteria according to the nature and the requirements of the programme;
—   control the relations with the other aspects of programme management.
This document covers the following subjects:
—   management of ILS (definition, implementation and running of the processes);
—   expression of the support requirements;
—   elaboration of the contracts (e.g. for development, maintenance, supply);
—   implementation of the tasks and processes.
This document is also related to the following subjects:
—   relations with costs and lead times control, configuration management, performance and RAMS management, quality assurance, documentation management;
—   regulations (e.g. information system security, export controls, safety at work);
—   human and organizational factors (HOF);
—   environment (e.g. RoHS, REACh);
—   information systems (IS) and the links between them;
—   logistics information systems (LIS);
—   in-service support (ISS) activities;
—   configuration management of ILS objects;
—   life cycle.
The following stakeholders are concerned by ILS:
—   users in the broadest sense: operators, maintenance operators, administrators, dismantlers of the system, trainers;
—   the customer, who:
—   prepares technical and contractual specifications of need with which the system will comply;
—   sets up the funding of the programme;
—   oversees the realization and commissioning of the main system and of the support system;
—   facilitates the feedback.
NOTE 1   At the highest level of the system, the customer can also be referred to as the “project owner”.
NOTE 2   The “main system” can also be referred to as the “system of interest”.
—   the supplier(s) who deliver a system (main and support) to the customer, which meets the performance specifications on time and for the agreed cost, throughout the system life cycle;
NOTE 3   At the highest level of the system, the supplier can also be referred to as the “industrial prime contractor”.
—   the regulatory authorities that supervise and approve the support processes and equipment, as needed.
The principles laid down in this document can be applied, after adaptation, to all the customer/supplier relations resulting from the breakdown of the main contract into sub-contracts.
