UL & FM APPROVALS
PROPERTY LOSS
PREVENTION
Product standards and approvals are ensuring quality, global
recognition, safety and standardization. Approvals and listings
are often required by the market and a listed mark shows
the customer that the product has been tested according to
some minimum requirements for its category. In addition, it
shows that the supplier has committed to regular tests and
audits as being performed by the approval organisation.
The UL and FM approvals are some of the most well
recognized global standards and being able to mark our
products with these adds great value.
