FAQs About Product Safety
Certification
(Questions with links to answers below)
- You really emphasize the fact that Abatement
products are tested and certified by ETL, a Nationally recognized testing
Laboratory (NRTL). What are the requirements?
- In the USA, OSHA safety standards for general industry
and construction and the National Electrical Code require testing and listing
(certification) of electrical products to applicable standards. It is important
to note that this testing must be performed on an electrical device even
if the individual electrical components used in that device are all listed
or approved. Testing must be done by an OSHA-recognized NRTL, such as UL
(Underwriters Laboratories), ETL (Environmental Testing Laboratories) or
CSA (Canadian Standards Association). In Canada, The Standards Council of
Canada has adopted standards for the Canadian Electrical Code developed
on its behalf by the Canadian Standards Association (CSA). Third party testing
from a laboratory or other organization not NRTL-certified is not acceptable,
even if such testing is done to applicable standards.
- Why is NRTL certification so
important?
- Unless a unit is properly tested, users have no way of
knowing whether it is properly and safely designed to meet the requirements
of the applicable electrical codes. It is wise to require written vendor
verification that the products you purchase are NRTL certified.
- Aren't all air filtration products
properly certified?
- No. Unfortunately, many of the air filtration systems
sold to and used by contractors, healthcare facilities and others are not
certified, especially negative air machines.
