SOME OF THE MANAGEMENT STANDARD.

• ISO 900O -QMS• ISO 14000 -EMS• ISO 18000-Occupational Health and Safety

Management System (OH& S MS) And International Standard OHSAS 18001:1999

• ISO 27000-ISO/IEC 27002 provides best practice recommendations on IS security management systems (ISMS).

EMERGING STANDARDS

• ISO-3834 –Quality requirements for fusion welding of metallic materials.• EN -15085- Welding of railway

vehicles and components.• IRIS- International Railway

Industry Standard

Welding is a Special Process-Why

• 7 - Product realization

• 7.5 Production and service provision

• 7.5.2 Validation of processes for production and service provision

– The organization shall validate any processes for production and service provision where the resulting output cannot be verified by subsequent monitoring or measurement and as a consequence, deficiencies become apparent only after the product is in use or the service has been delivered.

What is ISO-3834&EN 15085

• It is an international standard created by the welding professional

• ISO 9001 defines requirements for quality management system

• ISO 3834 also defines the quality requirements, only welded products.

• EN 15085 for railway applications.

What is ISO-3834&EN 15085(contd)

• The standard specifies the requirements relating only to the welded structure.

• The standard can also be used as a production control system.

• ISO 3834 is not a product standard, but it is often cited as a requirement of various products to ensure good practice in the welding and to prevent premature failures.

What is ISO-3834&EN 15085(contd)

• The standards provides details of how to control the various welding and welding-related operations to achieve the desired quality consistently

• The company that is certified according to this standard gains an advantage when competing with other companies in European and World wide markets.

ISO 3834 part-1 to 4

• ISO 3834-1-General requirements

• ISO 3834-2- Comprehensive quality requirement

• ISO 3834-3- Standard quality requirement• ISO 3834-4 -elementary quality requirement•

ISO 3834-2- Comprehensive quality requirement

Constructions in which the failure of welds may lead to

• total product failure • with significant financial consequences • Major injury. • The product may be subject to dynamic

loading • In addition to high static loading.

ISO 3834-3- Standard quality requirement

Constructions in which failure of welds • impair the intended use of construction.• Normal safety risk • Financial losses not extreme.

ISO 3834-4 elementary quality requirement

Constructions in which failure of welds • Not fundamentally impair the intended use. • No adverse effects on safety of people • Minor financial consequences.
