(1) sign identification

(2) safety requirements

(3) idling

6.2.3 before the prototype test, it is necessary to check whether the installation of the prototype is intact, and confirm that its rotating working parts rotate flexibly without jamming and abnormal noise. Then carry out the idling test, which shall not be less than 15min

6.2.4 see Appendix A for specific inspection requirements of each inspection item

7 determination principle

the LN determination method of inspection items shall be implemented in accordance with the provisions of Appendix A

principle: after inspection, all items of class a items are qualified, and there are no more than 2 unqualified items of class B items, so it is determined that the products to be sampled are qualified; Otherwise, it will be judged that the inspected product is unqualified

conclusion words:

through sampling inspection, the inspected items meet the requirements of * * standard, and are judged as qualified according to the implementation rules for random inspection of product quality supervision of Liaoning Mobile thresher

through sampling inspection, the * * items do not meet the requirements of * * standard, and are judged as unqualified according to the implementation rules for quality supervision and random inspection of mobile thresher products in Liaoning Province

8 objection handling

when handling objections to enterprises that are judged to be unqualified, the following methods should be followed:

8.1 verification no have you noticed these? Relevant evidence of qualified items can be proved by records (paper records, electronic records or video records) or other quality data associated with unqualified items
