c. Determination of flash point
GB 3536 using the methods specified in
d. Determination of refractive index
GB 6468 using the methods specified in
Methyl cyclosiloxane
6. Inspection Rules
a. in the same raw materials, the same proportion and the same process conditions, the production of a kettle or a few well-mixed reactor through the same type of products to a group.
b. each batch of products must be tested by a laboratory, and to ensure that a company's products meet the requirements of all the technical requirements.
This standard provided for in Article 4.1 and 4.2 levels of test items for a company, laboratories should be tested each batch of a company's products.
Upon examination, if the test results do not meet certain requirements of this standard should be re-double the amount from the product packaging pieces in the sample, conduct a review of the failed projects in order to re-examination it was decided to re-processing.
7. Logo, packaging, transportation, storage
a. logo, packaging
Test each batch of products are single-test a single in triplicate, a cross-shop, a warehouse with the product is called, a laboratory retained. Packed with drums (200 kg), drums are labeled self-adhesive side label, the label column filled in line proofs.
b. the transport, storage
This product is in transit should pay attention to rain, moisture and sun
This product is a non-dangerous goods
This product should be stored in ventilated, dry coffers, to prevent direct sunlight and should be cut off from the fire source. Products from the date of the production, storage period of three years, more than the standard storage period according to the provisions of this re-examination, if they meet quality requirements, can still be used. |
