The Importance of Furniture Testing
(Mandy)
For the furniture industry, furniture testing plays an important and irreplaceable role
in ensuring the quality of furniture products. Its influence on furniture enterprises is
mainly reflected in strengthening the effectiveness of enterprise quality
management, reducing the cost of enterprises, and enhancing the market
competitiveness of enterprises. The furniture testing system is perfected according to
its influence on enterprises and the needs of enterprises and consumers, to ensure
the scientificity, impartiality and authority of inspection and testing, and to
consolidate the importance of furniture testing in furniture enterprises.
At present, the testing of furniture products by furniture testing institutions mainly
focuses on four aspects: appearance testing, furniture mechanical performance
testing, furniture physical and chemical performance testing and environmental
performance testing.
(1) Appearance inspection: Visual inspection and on-site inspection are both
performed by visual inspection and ruler measurement. The main ones are
functional size, finishing, coating and so on. The functional size must meet the
requirements for use, and ensure that it is within the allowable tolerance range. If
the functional size does not meet the requirements, the product is a substandard
product, which reduces the performance.
(2) Testing of mechanical properties of furniture: The testing of mechanical
properties is a test that simulates the strength or bearing capacity of furniture under
one-time or repetitive load conditions in normal and habitual use. According to the
normal use frequency of the product under the predetermined use conditions, the
possible misuse strength, according to the size of the loading force and the number
of loading times, the strength and durability are divided into five test levels, that is,
the frequency of use is used to determine the test. level, the product is subjected to
static load, durability and impact tests.
(3) Testing of physical and chemical properties of furniture: seven indicators are
mainly tested, that is, the paint film is resistant to dry heat and moist heat, and wear
resistance, adhesion, gloss value, paint film thickness and paint film resistance to
cold and heat temperature difference. Among them, the adhesion of the paint film,
the wear resistance and the resistance to the temperature difference between cold
and heat are particularly important, which determine the service life of the paint film
on the surface of wooden furniture.
(4) Environmental protection performance testing: mainly to test free formaldehyde
and soluble heavy metals in wooden furniture. The national standard specifies three
methods for the determination of formaldehyde content or release: perforated
extraction method, dryer method, climate chamber method (environmental test
chamber method); to detect soluble heavy metal elements, scrape an appropriate
amount of coating on the surface of furniture products, According to national
standards, the content of soluble metals in paints and varnishes was determined by
atomic absorption spectrometry.

At present, in addition to the appearance inspection, the other three aspects can be
used to test the products submitted for inspection through the selection of scientific
testing methods and sophisticated equipment, and obtain accurate quality inspection
results, which are fed back to the research and development of enterprises,
Production and Quality Department. In this way, the enterprise separates
substandard products according to the test results, analyzes the quality problems,
and proposes corrective measures. Through this process of inspection, feedback and
correction, the improvement of the product quality of the enterprise is promoted.
Previously, Haida International Equipment has provided complete testing solutions
for 10,000 furniture manufacturers around the world, including chair test series
( BIFMA X5.1, EN1728, EN581, EN1335, EN1022 and other standards design), foam
test series ( ASTM D3574, ISO and other standard design), mattress test series (ASTM
F1566 and EN 1957 and other standard design), sofa test series (EN4875 and EN1728
and other standard design), VOC & formaldehyde test chamber (EN717 and other
standard design). All in all, what I want to say is how important furniture testing is,
and with the development of technology, we have corresponding good measures to
conduct testing, and strive to promote a better life for people all over the world.
