Mr. Kitchen and Bath found that the nine major categories of ceramic sanitary products, sampling methods, determination rules (based on standards, principles of determination) is not much different.Common sampling methods are random sampling method in the sampled producers, sellers of products to be sold. Random numbers can be generated using a random number table or other methods. The number of samples, test samples and spare samples per batch varies from 1 to 4. For details, refer to the related regulations. In addition, if the explicit quality requirements of the product under inspection are lower than, include or lack the mandatory standard requirements based on the inspection items in the Rules for the Implementation of the State Supervision and Sampling Inspection of Product Quality of 131 Products, they shall be determined in accordance with the mandatory standard requirements, the explicit quality requirements of the product under inspection and the mandatory standard requirements respectively. If the quality requirements of the product being tested explicitly lacks the recommended standard requirements based on the test project in the Rules, the project is not involved in the decision. It is worth noting that the “131 products quality state supervision and sampling implementation rules” is not applicable to the intelligent toilet seat, ceramic toilet seat, bathroom furniture, shower, sanitary ware hose, non-contact water nozzle, ceramic plate seal water nozzle, ceramic tile, ceramic tableware 9 categories of ceramic bathroom product quality state supervision and sampling of all standards. The implementation of enterprise standards, group standards, local standards of the product, test items are referred to the “131 product quality of state supervision and sampling of product quality Implementation Rules”. However, if the document has been dated, all subsequent amendment orders (excluding errata) or revisions are not applicable to the “131 products quality of state supervision and sampling of the implementation rules”. The latest versions of undated documents are also applicable to the 131 Rules for the Implementation of the State Supervision and Sampling Inspection of Product Quality.
