Thanks to its long-standing experience, JDT is able to

collaborate in the standardisation committee for round steel

chains (NRK).

This standardisation committee is responsible for the national

(DIN), European (CEN) and international standardisation (ISO)

in respect of round steel chains (round steel chains for general

purposes, slinging gear, lifting chains, conveyor chains, anti-skid

chains and seizing chains) , including the accessories.

Among others, JDT has taken the lead on defining the

requirements for high-strength chains of the grade 10

(PAS 1061).

In the mining standardisation committee (FABERG) JDT

collaborates on specifying the worldwide acknowledged

standard for mining chains (e.g. DIN 22255) and locks (e.g. DIN

22258).

In the iron and steel standardisation committee (FES) JDT

incorporates its long-standing experience in respect of

developing and using modern high-performance materials for

standardising chain steels (DIN 17115).

Certificates and licenses

ISO 9001: certified since 1994

DNV: Type Approval in accordance with 2.7-1 (Offshore

Containers) since 1999,

BG: JDT was issued with the H3 stamp in the 1960s as the first

manufacturer of slinging chains. In 2008 BG confirmed the high

quality of the standard 10 (ENORM) for slinging gear as part of a

license.
