proactively on all reported cases in a
timely manner by carrying out reviews,
evaluations and investigations, followed
by immediate corrective or preventive
actions to satisfy our customers’
preferences.
VTech Quality Laboratories
To improve the quality, durability and
performance of our products, we have
set up our in-house product testing
laboratories (labs) at the manufacturing
sites of our three product lines. All our
products must go through reliability
tests during different design stages. The
comprehensive tests provide data for
our engineers to improve the quality and
reliability during the stages of production,
transportation, storage and throughout
the intended product life cycle under a
wide range of use conditions. Ongoing
reliability test is also conducted during
the mass production stage on a
sampling basis to detect any anomalies
or changes that may occur in the design,
supply chain or production process
that adversely changes field reliability
performance of our products.
The reliability lab of TEL products is
designed based on the international
requirements and standards, and our UL
Safety Lab is the first telecommunication
manufacturing facility to comply with
UL 60950 in Guangdong. Our in-house
physical and chemical laboratory of ELPs
is a China National Accreditation Service
(CNAS) certified laboratory for ASTM
F963 & EN71-1 (specific test items)
standards since 2011 and complies
with ISO 17025 standards. Equipped
with advanced testing instruments, our
in-house chemical laboratory is also
able to test specific chemicals such as
heavy metals and phthalates. Samples
of our VTech products are also sent to
independent safety testing labs before
they are brought to market to ensure
that they meet the highest levels of
international and local quality and safety
standards.
