Frequently asked questions
When a trailer is first manufactured it must pass all the necessary safety and quality standards before it can be sold or registered throughout European member states, this is known as European type approval. Since 29 October 2012 all newly manufactured trailers must be type approved.
It is a trailer which has the following EU categories.
O1 – Trailer with a Design Gross Vehicle Weight (DGVW)* of 750 kg or less
O2 - Trailer with a Design Gross Vehicle Weight (DGVW)* over 750 kg but not exceeding 3,500 kg
*DGVW or maximum authorised mass (MAM) is the weight of a vehicle or trailer including the maximum load it can carry as per the manufacturer’s design specifications.
The national standards authority of Ireland ( NSAI) is the appointed approval authority in Ireland responsible for issuing all national approvals e.g., IVA or NSSTA for brand new unregistered vehicles only.
This relates to an individual vehicle or trailer. Each trailer is checked and on passing inspection at an NSAI appointed test centre (ATC) an IVA cert is issued.
This is certification for small batches of trailers to a maximum of 500, intended for Irish or national use. When NSSTA is granted the manufacturer can issue a CoC for each trailer of same type.
This certification is issued to manufacturers of large quantities of the same type of trailer. Instead of having to obtain approval for each and every trailer one model or prototype is used. If that one trailer is approved, then a certificate of conformity (CoC) will be issued to all trailers of the same type.
This is issued to the manufacturer as proof that the trailer achieved type approval and can be sold throughout European member states.
For new trailers contact the original manufacturer.
To obtain type approval for brand new trailers contact the NSAI.
No. Under EU law, mutual recognition of national approval schemes is only permissible between EU Member States.
Any new trailer built since 29 October 2012 must be type approved and have a CoC. This ensures that the design, lighting, braking etc. has met a European safety and quality standard.
