4 Inspection Rules
4.1 Product test is classified into type test, exit-factory inspection and receiving
acceptance.
4.2 Under the following conditions, type test must be carried out on products.
a) For products that art newly launched into production (including those in
transfer-plant production), type test shall be carried out before production
identification;
b) For continuously produced products, type test shall be carried out every 3-year
on those products that have passed the exit-factory acceptance;
c) Where the design, process or main component changes that affect the product
performance, type test shall be carried out before putting into production;
d) For products halting for more than two years, type test shall be carried out
before resuming the production.
4.3 Each product shall be subject to exit-factory inspection, and can only be
measured and standard test atmosphere conditions, namely.
a) Environment temperature. +15~+35°C;
b) Relative humidity. 45%~75%;
c) Atmospheric pressure. 86~106kPa.
