6 Inspection rules
6.1 Fragrance compound shall be inspected by the quality inspection department of producer. The producer shall ensure that the ex-factory products meet the requirements of this standard. Each batch of ex-factory products shall be accompanied by a quality certificate. In addition, the producer shall inform the customer in writing of the highest amount of the fragrance in eleven categories of fragranced products or specified products. The color, aroma, relative density and refractive index are the ex-factory inspection items, and the type inspection is the overall inspection, which is carried out once a year.
6.2 The acceptance unit has the right to inspect whether the quality of the products received meets the requirements of this standard. Each batch is subjected to one acceptance and the different batches are separately accepted.
6.3 Sampling method: 1 to 2 packaging units per batch: sample it or both; 3 to 100 packaging units per batch: sample 2 units; the portion over 100 units: re-sample 3%. Use a sampler to uniformly extract 50 mL to 100 mL of the test sample from each packaging unit, and place all the extracted test samples in the sample mixer and mix them thoroughly into two clean, dry, sealed inert containers. Keep them away from light. Label the container with the name of the manufacturer, the name of the product, the date of manufacture, the batch number, the quantity and the date of sampling. One bottle is for inspection and the other bottle is reserved for future reference.
6.4 If one of the acceptance results does not meet the requirements of this standard, it may be re-tested with double test samples together jointly with the producer. If still one item fails to pass the retest, this batch of products shall be judged as rejected.
6.5 When the supplier and the buyer disagree with the quality of the product, the dispute may be settled by agreement between the parties or arbitrated by a statutory inspection agency.
