b) When raw materials and formulation have significant changes, which may affect

the product performance;

c) Conduct the inspection every three years for normal production;

d) Restore production when shutdown for more than half a year.

7.2.2 Sampling

Conduct sampling from the qualified products in exit-factory inspection.

7.2.3 Judgment

After inspection, if there are disqualified items, allow for double sampling and

re-inspecting. After that, if there are still disqualified items, then such batch of product

shall be judged as disqualified.

8 Label, Package, Transportation and Storage

8.1 Label

After test is qualified, the products shall have the following labels.

a) Trademark;

b) Serial number;

c) Product name;

d) Specification, model;
