Plug boards are commonly used electronic products. According to different quality standards, the inspection
points/inspection methods are also slightly different.
This inspection guide applies to patch panel products and is intended to ensure that the products comply with
relevant European Union (EU) standards and regulations. The goal of this inspection guide is to ensure the quality,
safety and compliance of the product.
This guide is for reference only and should be combined with actual application!
1. Applicable standards
Product quality inspection will be carried out according to the following relevant EU standards:
EN 60950-1:2006+A11:2009+A1:2010+A12:2011+A2:2013 - Safety of information technology equipment
(including electronic equipment) - Part 1: General requirements
EN 60884-1:2019 - Plug and plug devices for plugs and socket-outlets and socket-outlet switches - Part 1:
General requirements
2. Inspection items
1) Appearance inspection
Power strip casing: Check whether the casing is complete and whether there are scratches, cracks or deformations
on the surface.
Socket hole: Make sure the size and shape of the socket hole meet the standards and have no obvious defects.
Plug: Check the appearance of the plug to make sure the pins are complete, symmetrical, and fit correctly into
the outlet.
2) Electrical performance inspection
Rated voltage and current: Verify that the product's rated voltage and current meet the standards.
Insulation resistance: Measure the insulation resistance of the product to ensure it is within the standard requirements.
Withstand voltage test: Conduct voltage withstand test to ensure that the product can safely withstand the rated voltage.
3) Safety performance inspection
Overcurrent protection: Make sure the power strip has overcurrent protection to prevent overloading of electrical
appliances.
Overheating protection: Check whether it has overheating protection to prevent fire or other safety issues caused by
overheating.
Material flame resistance: Check the flame resistance of product materials to ensure that no toxic gases will be
produced in the event of a fire.
3. Inspection methods
Appearance inspection can be done by visual inspection and dimensional measurements.
Electrical performance checks should be carried out using suitable measuring equipment.
Safety performance checks can be carried out through actual testing and review of certification documents.
4. Inspection frequency
Inspection frequency should be determined based on production batch size and product historical performance to ensure
adequate coverage of different batches and variations.
5. Records and reports
Each inspection should have detailed records, including inspection date, product batch number, inspection personnel
information, etc. Products that pass the inspection should be issued with a certificate of conformity and the inspection
results report should be filed.
6. Improvement and tracking
Based on the inspection results, develop improvement plans and track implementation. Ensure that identified quality
issues are addressed promptly to improve product quality and compliance.
