ER Certification extends its Quality Mark

ER Certification Ltd has taken a number of steps to help ensure it continues to provide its clients in the glazing, window and door manufacturing industries with a first-class service...


Mandatory CE Marking

With the introduction of mandatory CE Marking for glass units, toughened safety glass, doors and windows and other construction products being effective from 1st July 2013, ER Certification Ltd extended the scope of its UKAS accreditation in anticipation of increased demand from manufacturers.

The move has helped the company  stay at the head of its field as an Independent Agency for the BFRC Window Energy Rating and Doorset Energy Rating schemes. Combined with its specialism solely within glazing, window and door manufacturing industry, ER Certification Ltd remains perfectly placed to provide efficient and cost-effective solutions to manufacturers.

ER Certification Ltd’s CMS Quality Marks currently include EN1279 for insulating glass units, EN12150 for toughened safety glass and EN14351 for windows & doorsets, with certification undertaken by the company’s team of dedicated glass and fenestration industry professionals.


Secured by Design approval

Following its selection as an approved Secured by Design certification provider, ER Certification Ltd is able to provide a full auditing service for window and door manufacturers seeking to gain Secured by Design approval for their products.

Overseen by the Association of Chief Police Officers (ACPO), Secured by Design is involved in a range of national police projects which seek to ensure that security is designed into both domestic and commercial properties. The organisation uses a number of certification bodies to ensure that approved products are manufactured to agreed quality and performance standards, with ER Certification Ltd licensed to provide the required certification of companies wishing to supply enhanced security windows and doors under the scheme into the UK market. Once approved by a certification body, manufacturers will be accepted into the Secured by Design licensing scheme, which allows use of the Secured by Design logo and the term 'Police Preferred Specification' in marketing collateral.

In order to meet the Secured by Design criteria, ER Certification Ltd will expect window and door manufacturers to be operating a Factory Production Control (FPC) system to comply with the European Standard EN14351 and additionally to have appropriate, independent testing conducted by ERC Testing Ltd. at prescribed intervals.
