AWL are pleased to have helped Metro Plating Ltd confirm the quality of their surface coatings using rotary Taber abrasion wear testing. #testing #taberabrasion #coatingsolutions

Drivers are being warned of two big changes to number plates that will come into force from March 2022.

From March, standard number plates on all new vehicles will need to pass durability tests to make sure they’re tough enough to withstand abrasion from road debris like salt and dirt.

The new rules also mean two-tone number plates, which use different colour shades to create a 3D effect on the lettering will be banned.

The new rules also mean two-tone number plates, which use different colour shades to create a 3D effect on the lettering, will be banned.

This is so that Automatic Number Plate Recognition (ANPR) cameras will be better able to read the lettering.

The new rules are all part of a new standard for number plates.

The old standard used BS AU 145d plates, which has been in use since September 2001, according to Autotrader.

The new standard is BS AU 145e:2018.

AWL are UKAS accredited to provide testing according to the requirements of ISO 12944 parts 6 and 9. We are pleased to have helped Euroclad Group Ltd achieve corrosion durability conformance to C5M, C4H and C3VH.

ISO 12944-6 testing alongside ISO 12944-9 are used to demonstrate the durability of new paint systems for benchmarking a corrosion category where performance data is not available. Durability categories are assessed at AWL Ltd after the humidity condensation test (ISO 6270-2), the neutral salt spray test (ISO 9227), and resistance to the effects of water or chemicals (ISO 2812-1 or 2812-2)  depending on the target category required.

This corrosion performance standard remains popular at AWL particularly for benchmarking a performance standard for a paint or other coating system where no previous data exists. There are 2 test regimes used to reach a performance standard. Test regime 1 requires water condensation AND neutral salt spray testing. Test regime 2 requires cyclic ageing in accordance with the old ISO 20340, now ISO 12944-9.

Test regime 2 should be chosen if UV weathering and low temperature durability is required for resistance to colour-shift, chalking, cracking, flaking or any other surface effects. It should be noted that chalking caused by UV degradation can significantly reduce the corrosion protection performance of any barrier coating.

Please also be reminded there are essentially 3 parts to establishing an ISO 12944-6 corrosion performance standard. These are:

1. Pre-exposure adhesion tests (test method depends on total dry film thickness)
2. The exposure cycles (regimes 1 or 2)
3. Post-exposure adhesion tests.

There may also be a requirement for a Cathodic Dis-bondment test in accordance with ISO 15711 if coating protection is cathodic rather than just barrier. In the 2018 version of the standard this is a recommendation only. AWL can offer CD testing if required.

All results must be satisfactory according to the requirements of the standard before a certificate of conformance can be issued. For more information please contact us

The short answer is yes but only if they have provided satisfactory test results according to all clauses of BSAU145e:2018 before they reach the UK market place.

The financial investment required for conformance to this standard is significant (+£14K) and the time-frames for compliance are long (+4 months).

We are hearing of lots of suppliers of this type of plate suggesting their product is indeed compliant to this standard so legal to sell in the UK. If they are compliant, they certainly didn’t come through us!!

We have not tested, or provided traceable C of Cs for any 4D plate construction since the standard became a legal requirement for plates sold in the UK!!

A few questions to suppliers / manufacturers of 4D construction number plates selling within the UK:

Do your customers have access to the test reports and a certificate of conformance? Was the certificate provided by a UKAS accredited laboratory?

So in summary, if the preferred testing laboratory according to the BNMA are not testing and providing evidence for BSAU145e:2018 conformance of 4D plates then……Who is?

.

We are contactable for contract review discussions should you have a requirement for any testing in line with our scope.

Our labs are fully operational and shall remain open for business.

In accordance with the latest UK government COVID 19 advice, most of our staff have been furloughed. Meetings or contact shall take place virtually or by email for the foreseeable future. We will continue to monitor the situation and advise you, via this website if anything changes.

May I take this opportunity to wish all of you a safe journey through this pandemic and I look forward things returning to some sort of normallity within the coming months. Stay safe and best wishes to all.

AWL are pleased to be helping Eco-Sol Ltd confirm the weathering durability of their fire-retardant coatings that are impregmated into various types of timber cladding after accelerated weathering in accordance with EN927-6 / Method B. This weathering test is required prior to cone calorimeter flammability testing according to EN 16755 -2017.

This corrosion performance standard still remains popular at AWL, but please remember there are 2 test regimes allowed to reach your required performance standard. One of which requires water condensation AND neutral salt spray testing. The other requires just cyclic ageing in accordance with the old ISO 20340, now ISO 12944-9.

Please also be reminded there are essentially 3 parts to establishing an ISO 12944-6 corrosion performance standard. These are:

1. Pre-exposure adhesion tests (test method depends on total dry film thickness)
2. The exposure cycles (test regimes 1 or 2)
3. Post-exposure adhesion tests.

There may also be a requirement for a Cathodic Disbondment test in accordance with ISO 15711 if coating protection is cathodic rather than just barrier. In the 2018 version of the standard this is a recommendation only. AWL can offer CD testing if required.

All tests must be satisfactory before a certificate of conformance can be issued by AWL Ltd. For more information please contact us
