6 Inspection rules
09 1779 -93
.1 Each batch of finished products should be accompanied by a production inspection certificate: "Production inspection" should ensure that all products meet the requirements of this standard. Each batch of products should be accompanied by a quality certificate, which includes the manufacturer's name, product name, trademark, date of manufacture, batch number, product certification and the number of this standard: 2 The acceptance unit has the right to accept the items of this standard and inspect the received products to see if they meet the requirements of this standard. One batch is inspected once, and different numbers are inspected separately. 6.3 For each batch of packaging units, two (bottles) are selected for analysis if the number is less than 1 (bottle) and three (bottles) are selected for analysis if the number is more than 1 (two). When opening the package for sampling, check the moisture and quality of the product on the outside, then vibrate to mix it, take the sample from the bottle (suck the sample evenly), inject it into the sampler, and put it into two bottles respectively. Note: manufacturer and product name, batch number, quantity and sampling date. Keep one bottle for inspection: see the inspection point for future reference. 6.4 If any of the following inspection results do not meet the requirements, The manufacturer may retake samples for re-testing. If the re-testing results still show unqualified indicators, the batch will not be accepted. .5 When the quality of the product is different between the supplier and the developer, the two parties may solve the problem or the legal inspection agency shall be responsible for the cost.
6.6 Color, gas, acid resistance, and chemical content are factory inspection indicators. Relative humidity, refractive index, irradiation, and micro-brightness are type inspection indicators: dynamic range is measured once. — 45 -
7 Marking, packaging, transportation, storage
Q8 177993
7.1 The formaldehyde should be packed in a fuel barrel or a fire extinguisher: the product name, manufacturer name, trademark, batch number, net weight, tare weight, factory date, standard code and relevant packaging special marks should be marked on the outside of the package. If there are special requirements in the order form, they can be negotiated with the manufacturer.
.2 During transportation, it should be prevented from being exposed to the sun, rain and foreign air pollution, and should be strictly protected from acid and water. 7.3 The product should be stored in a dry, ventilated, and shaded warehouse. Prevent foreign air pollution and keep away from fire sources. 7.4 Under the specified transportation conditions, packaging is complete, and the product is not opened, the warranty period is one year. 46
