Quality & Certifications
Reliable quality control systems to enable maximum performance
Quality you can count on
Customer satisfaction is our number one priority at GD Rectifiers
We aim to achieve customer satisfaction through superior product marketing, comprehensive inventory, a friendly and professional sales team and engineer expertise.
We test and approve our product range of power assemblies, selenium rectifiers, heatsinks and high voltage diodes for functionality, safety and durability. The brands that we stock have rigorous quality control systems, each product is tested and approved as part of the manufacturer’s process before launching to market.
GD Rectifiers do not alter or test manufacturer products, we simply distribute their product range. Only products that pass our strict quality expectations are added to our product portfolio.
Our GD Rectifiers quality control processes with requirements set out in the following standards enable us to deliver an unrivalled level of product quality and service to our customers.
ISO 9001:2015 – the leading management standard for companies that trade on a business-to-business basis
RISQ – the UK’s rail industry supplier qualification scheme providing a single common registration, qualification and audit process
BS EN 60947-4-3:2014 standards – compliance in low-voltage switchgear and control gear, contactors and motor starters, AC semiconductor controllers and contactors for non-motor loads
BS EN 60146-1-1:2010 standards – compliance in semiconductor converters, general requirements and line commutated converters, specification of basic requirements
RoHS Compliant – we strive to provide RoHS compliance in our products manufactured in-house
The RoHS (Restriction of Hazardous Substances) Directive is a set of criteria formulated by the European Union (EU) to regulate the use of toxic materials in electrical and electronic products. The Restricted substances referred to in Article 4(1) and maximum concentration values tolerated by weight in homogeneous materials include:
- Lead (0,1 %)
- Mercury (0,1 %)
- Cadmium (0,01 %)
- Hexavalent chromium (0,1 %)
- Polybrominated biphenyls (PBB) (0,1 %)
- Polybrominated diphenyl ethers (PBDE) (0,1 %)
- Bis(2-ethylhexyl) phthalate (DEHP) (0,1 %)
- Butyl benzyl phthalate (BBP) (0,1 %)
- Dibutyl phthalate (DBP) (0,1 %)
- Diisobutyl phthalate (DIBP) (0,1 %)
GD Rectifiers will indicate environmental compliance on parts where the original manufacturer has provided GD Rectifiers with clear objective evidence of RoHS compliance, or where the OEM’s datasheet and own website pages reference the certification. Environmental compliance should be based on manufacturer’s documentation, and not the distributors.
GD Rectifiers performs no testing of products and relies solely on the manufacturer of the product for identification of Environmental Compliance. GD Rectifiers makes no warranty, certification, or declaration of compliance. All statements by GD Rectifiers on Environmental compliance, are based on Manufacturer documentation. Products will not be advertised or offered as Environmentally Compliant, until the manufacturer has confirmed its conformity. GD Rectifiers has made every effort to provide a true representation of products that are RoHS compliant, however we reserve the right to change a products RoHS status on our website if incorrectly applied, or if the status changes over time.
The EU Directive on Waste Electrical and Electronic Equipment (WEEE, Directive 2012/19/EU) establishes common rules for the management of electrical and electronic equipment and how to minimise its impact on the environment—from design until disposal. As a distributor of electrical and electronic equipment, we actively support the requirements of the WEEE Directive and encourage all our customers and end users to make responsible decisions when it comes to the disposal of products. When you recycle WEEE you are helping to ensure that they are neither incinerated or sent to landfills, thereby minimising the potential negative impact on human health and the environment.
REACH (Regulation, Evaluation, Authorisation and Restriction of Chemicals) is an expansive set European Union regulations that focus on chemical safety and reduce the use of harmful chemicals across all industries doing business in the EU. The European Chemicals Agency (ECHA) on 1/14/09 developed the first draft recommendation of substances of very high concern (SVHC) for inclusion in Annex XIV. There are now over 50 SVHCs and the list keeps growing.
As a distributor of electronic components, GD Rectifiers has a limited role in REACH compliance. Although electronic components and supplies can be characterised as articles and substances, GD Rectifiers is a manufacturer of “Articles” to our EU customers under the REACH regulation. We do not manufacture “substances” or “preparations” and our articles do not involve the “intentional release of substances”. Therefore, we foresee no registration or pre-registration or authorisation requirement for the products we supply.
We declare none of the SVHCs (Substances of Very High Concern defined by the EU effective 27 June 2018) are present in GD Rectifiers’ products. As a distributor, GD Rectifiers has the responsibility to communicate SVHC information down the supply chain when provided by the manufacturer, per article 33 of the regulation.
GD Rectifiers expects manufacturers to have robust environmental programmes that adhere to the requirements of REACH and to identify and share SVHC information with GD Rectifiers. GD Rectifiers has made suppliers aware of our above expectations and in the presence of SVHC, we will communicate this to our customers, and provide them with a Safety Datasheet as required by article 33 of REACH.
As with RoHS, not all the products we sell will be REACH compliant at one time. For this reason, GD Rectifiers encourages customers to take an active role in understanding environmental compliance of products and selecting them accordingly.
CE Certification & Marking
CE certification and CE marking are a part of the EU’s harmonised legislation created in the early 1990s. The original aim of the CE marking was to facilitate the free movement of goods in the European single market, with a policy geared to ensuring that only safe and otherwise compliant products found their way into that market.
Today there is 25 CE directives and most EEE (Electronic and Electric Equipment), as well as some electronic components, are required to be CE certified to be suitable for the EU/EEA Market.
Until 2020, the UK also used CE, however following the exit of the United Kingdom from the European Union, the UK has since created its own certification: UKCA, which went live in January 2020.
UKCA follows the same principles as CE yet modelled specifically on the legislation and designated standards of the United Kingdom. CE will cease to be recognised in Great Britain throughout 2022 and will be replaced by the UKCA marking as a mandatory requirement on products from 1st January 2023.
As a UK distributor, GD Rectifiers are working closely with suppliers on the UKCA compliance and will update our product information as soon as we have received confirmation from our manufacturers.
Conflict Minerals Regulation Statement
In August 2012 the United States Securities and Exchange Commission issued its final rules regarding “Conflict Minerals” as defined in section 1502 of the Dodd-Frank Act. As a result, many companies worldwide are now focusing on whether and to what extent their products contain so called Conflict Minerals and whether such minerals come from the Democratic Republic of Congo and the adjoining countries named in the Act.
In response to the EU Conflict Minerals Regulation and the US Dodd-Frank Act – Section 1502 regarding Conflict Minerals, also known as ‘3TG’, GD Rectifiers strives to continually demonstrate our commitment to ensuring the health, safety and protection of the people who come in to contact with our products and business. We ensure our suppliers comply with the regulation and source materials in a socially, economically and environmentally responsible way, adhering to the OECD Guidelines for Multinational Enterprises and the UN Guiding principles on Business and Human Rights.
The common derivatives from these Conflict Minerals include: Tantalum, Tin, Tungsten, and Gold. We are continually working towards ensuring that we do not have Conflict Minerals sourced from Conflict Mines in our products and are therefore committed to:
- Ensuring that we do not purchase Tantalum, Tin, Tungsten, or Gold from Conflict Mines
- Asking our suppliers to take the necessary steps to ensure that products supplied by them to us do not originate from mines that support or fund conflict within the Democratic Republic of Congo and adjoining countries named in the act
- Ask suppliers to comply with all national and other applicable laws and regulations, adopt sound human rights practices and treat workers fairly with dignity and respect, and provide a safe and healthy working environment for their workers
- We recognise that implementing this policy will take time and that full implementation of this policy is dependent on us receiving on-going support from our suppliers
GD Rectifiers works closely with all of our suppliers to ensure to the best of our knowledge we are not distributing any products that contain Conflict Minerals or products which use Conflict Minerals in their manufacturing processes. As part of this process GD Rectifiers demonstrates due diligence by informing all of our suppliers that by accepting our orders, they are agreeing to supply said products to GD Rectifiers which do not use any raw materials in their manufacture that are defined as Conflict Minerals.
