July 28, 2010 Joint stock company (UAB) AF Inspection LT changes the name to JSC (UAB) DEKRA Industrial.

The internationally active expert organisation DEKRA has acquired 100% of the Swedish industrial testing & inspection provider ÅF-Kontroll AB. The purchase agreement was signed on the 25th of March in Stockholm. ÅF-Kontroll is the owner of AF Inspection LT, UAB.

March 2010 12 employees were certified according to PNAEG (standards and norms of nuclear power engineering) and received UT 2 level certificates.

March 2010 12 employees were certified according to PB 03-440-02 and received UT 2 level certificates.

January, 2010 our company had got certificate of international inter-laboratory testing (PT) confirming our successful participation in metal impact test programme.

December, 2009 accreditation scope was extended by adding Brinell methods metal hardness tests, the fracture test and metal impact tests (destructive testing) and leak testing and austenite weld ultrasonic testing (non-destructive testing) in accordance with Lithuanian standards.

November, 2009 our company had got certificates of international inter-laboratory testing (PT) confirming our successful participation in the determination of the resistance to inter-granular corrosion in stainless steels and in the determination of the real grain size.

From March to May 2009 UAB „AF Inspection LT” and ÅF-Kontroll have performed the UT and ET inspection of Oskarshamn NPP (Sweden).

November, 2008 UAB „AF Inspection LT” together with
ÅF-Kontroll did start the development of the procedures for Ringhals NPP reactor pressure vessel automated UT and ET testing.

October 2008 four employees were certified according to Nordtest/EN473 and received UT 2 level certificates.
