▍What is WERCSmart REGISTRATION?

WERCSmart is the abbreviation of World Environmental Regulatory Compliance Standard.

WERCSmart is a product registration database company developed by a US company called The Wercs. It aims to provide a supervision platform of product safety for supermarkets in US and Canada, and make product purchasing easier. In the processes of selling, transporting, storing and disposing products among retailers and registered recipients, products will face increasingly complicated challenges from federal, states or local regulation. Usually, the Safety Data Sheets (SDSs) supplied along with the products do not cover adequate data of which information shows compliance with laws and regulations. While WERCSmart transforms the product data to that conforming to laws and regulations.

▍Scope of registration products

Retailers determine the registration parameters for each supplier. Following categories shall be registered for reference. However, the list below is incomplete, so verification on registration requirement with your buyers is suggested.

◆All Chemical Containing Product

◆OTC Product and Nutritional Supplements

◆Personal Care Products

◆Battery-Driven Products

◆Products with Circuit Boards or Electronics        

◆Light Bulbs

◆Cooking Oil                      

◆Food dispensed by Aerosol or Bag-On-Valve

On March 20, KATS issued an official document 2023-0027, officially releasing KC 62619:2022.Compared with KC 62619:2019, KC 62619:2022 has the following differences:The definition of terms has been modified to align with IEC 62619:2022, such as adding the definition of maximum discharge current and adding time limit for flame.The scope has been changed. It is clear that mobile ESS batteries are also within the scope. The range of application has been modified to be above 500Wh and below 300kWh.Requirement of current design for battery system is added. The battery should not exceed the maximum charge/discharge current of cell.Requirement of battery system lock is added.Requirement of EMC for battery system is added.Laser triggering of thermal runaway in thermal propagation test are added.
Compared with IEC 62619:2022, KC 62619:2022 has the following differences:
Scope: IEC 62619:2022 is applicable to industrial batteries; while KC 62619:2022 specifies that it is applicable to ESS batteries, and defines that mobile/stationary ESS batteries, camping power supply and mobile electric vehicle charging piles fall within the scope of this standard.
Sample quantity: In 6.2, IEC 62619:2022 requires the number of samples to be R (R is 1 or more); while in KC 62619:2022, three samples are required for each test item for a cell and one sample for battery system. KC 62619:2022 adds Annex E (Functional Safety Considerations for Battery Management Systems) which refers to Annex H of functional safety-related standards IEC 61508 and IEC 60730, describing the minimum system-level design requirements to ensure the integrity of safety functions within a BMS.
