The Code of Practice, for a single use flexitank system, forms part of the COA shipping line (carrier) risk assessment process.

The Code, V5 includes amendments to include reference to the newly published standard PAS 1008:2016. There are also editorial changes.

The Code requires flexitank manufacturers to comply with the Code and ensure a safe and reliable flexitank system.

Compliance with the Code requires that each manufacturer undergo four quality management audits for each type of flexitank manufactured. The four audits are as follows:

  1. ISO 9001 quality management.
  2. Installation, operating and training instruction manual.
  3. Material test.
  4. Rail impact test.

Audits for ISO 9001, Installation/training and material tests are valid for three years, the rail impact test five years.

Material tests and rail impact tests are completed to PAS 1008:2016. To allow for a transition period to repeat any existing test not completed in accordance with PAS 1008:2016, the existing test shall remain valid until December 2017 except where there is a variation in design as defined by PAS 1008:2016

Rail impact tests are required to be carried out at a COA nominated test centre. There are currently four test centres:  TüV Süd Rail (Görlitz, Germany) TCCI/AAR (Pueblo, Colorado, USA), BJTU (Beijing China) and CRCC (Beijing China).

Material tests and rail impact tests are carried out to the provisions of PAS 1008:2016, Specification for the performance testing of a single use flexitank. PAS 1008:2016 is a standard available from and other ISO standard suppliers.
