Showell, John F

Assisting electronics companies with product safety certification

Details

Services Provided:

Product Approvals Ltd is a consulting engineering practice specialising in helping electronics companies with obtaining product safety approvals, for example CE marking for the European market and nationally recognised testing laboratory (NRTL) marking for the North American market using third-party agencies such as Underwriters Laboratories (UL). Here are some further benefits to you of using my services:

Completely impartial advice aimed at helping you fulfill your specific product approvals requirement.
An in depth understanding of the unique requirements for electronic products
An emphasis on tailoring a solution to your unique needs.
A hands-on approach if that's what you need.
Over 15 years experience in obtaining UL approval
Knowledge of standards including UL 508C Power conversion equipment, UL 840 Insulation co-ordination, UL 50 Enclosures for electrical equipment, UL 746 Polymeric material use in electrical equipment, UL 1449 Transient voltage surge suppressors, EN 61800-5-1 Electrical power drive systems, EN 50178 Electronic equipment for use in power installations, EN 60529 IP codes, NEMA-250 Enclosures for electrical equipment, Canadian standard CSA C22.2 No. 14 Industrial Control Equipment etc.
Determination of optimal product certification routes.
Additional flexible resource as and when you need it.
A means of staying up-to-date with current legislation affecting electronics equipment.
Design reviews - on site - or by web conferencing.
Custom-written design guidelines

The service will be tailored to best suit your unique requirements.

Preliminary safety design reviews. To help ensure conceptual designs are compliant with key safety requirements from the outset of the project.
- Service code PSDR1 (on-site)
- Service code PSDR2 (web based)
Project management and facilitation of third-party safety approval submittals e.g. obtaining agency listings for US and Canadian markets.
- Service code TPSA
Assistance with self-certification CE-marking of products to the Low Voltage Directive for the EU market.
- Service code SCA-LVD
Creation and implementation of complete product design verification plans to address product conformity aspects including safety, EMC, environmental (climatic, vibration), user-interface, integrity and reliability aspects as required.
- Service code PDVP
Review of market entry product approval options. For example investigation of alternate certification agency routes and product label markings.
- Service code ME
Legislation monitoring. This could for example involve monitoring of a key safety standard - or looking at the implications of new EU legislation such as the Energy-using Products (EuP) directive.
- Service code LM
Design guideline writing. This can be a valuable aid to reducing time spent by design engineers navigating and interpreting sometimes confusing or complicated information laid-out in technical standards. Collating differing requirements across various applicable standards when considering e.g. PCB clearance requirements is another example of a potential benefit.
- Service code DG
Data research and collation. This service can be of help for example when selecting suitable polymeric materials for an electrical enclosure and can include review of relevant parameters such as flammability, relative thermal index for electrical & mechanical performace, comparative tracking index, arcing and hot wire ignition resistance and so forth.
