What is DIN6701 About:
The aim of DIN6701 standards is to prove and ensure quality in the area of adhesive bonding in the rail vehicle industry and in rail parts maintenance. It comprises four parts:
- DIN 6701-1: Basic terms and basic regulations.
- DIN 6701-2: Qualification of companies that use adhesives (user-companies) and their employees, compliance evaluation. This represents the basis for the certification. It deals with the accreditation of user-companies, which may be companies that use adhesive bonding to manufacture or repair rail vehicles.
They must also undergo certification. However, this is only so if the relevant bonded joints have high or average safety requirements.
They can also be companies that:
- Purchase and sell on or
- Purchase and fit/assemble bonded parts and components or
- Contract third parties to carry out adhesive bonding.
- DIN 6701-3: Design specifications – guideline for construction, dimensioning and proof thereof.
- DIN 6701-4: Regulations for manufacturing adhesive bonds and quality assurance.
Why Does DIN6701 Exist?
DIN6701 took effect in 2006 in response to an increasing number of damage events in the welding and adhesive bonding process associated with the rail industry. It has been revised every year and is an up-to-date standard of reference on an international scale, certifying quality assurance, safety and high security.
Currently, all railway manufacturers require adhesive bonding to be designed and executed according DIN6701, regardless of whether the adhesive is applied within the production plant or by a supplier.
DIN6701 International Recognition
DIN6701 is a German standard that has reached the international level. Indeed, even if the outset was mainly national, a lot of international parties have participated in the creation of this standard of reference that is recognized on an international level in adhesive bonding work in the rail vehicle manufacturing sector. The adoption of DIN6701 is due to the previous lack of standards in this environment and the German rail industry’s preference for working with companies that comply with DIN6701.

How to Get DIN6701 Certified
DIN6701 standard define three core concepts that must be met:
- Classification of bonded joints in accordance with safety requirements
- Appointment of supervisors in charge (SICs / VKap) of adhesive bonding work
- Verification: Actual load < Load limit of the bonded joint
DIN6701 not only enables manufacturers to communicate more widely with industries interested in DIN6701, but also facilitates a lot of benefits for the company itself. However, it requires a significant effort in training several applicators, supervisors and a VKap EAE:
- Beneficial technological and economic outcomes in the medium term
- Minimizes mistakes
- Generates trust
- Promotes a more sustainable image of adhesive bondings
