Salt spray test chamber - problems in the salt spray test chamber and methods and countermeasures to ensure the quality of its use The salt spray test chamber is used as a product environmental test equipment, especially as a test equipment used for quality inspection by the quality inspection department. In order to give full play to its role, in addition to the user's correct operation and maintenance according to the technical requirements of the manufacturer, It is also necessary to check the quality of the action (basic teaching of the salt spray test chamber) at regular intervals to make sure that the salt spray test is accurate. On the other hand, if the salt spray test chamber is not of good quality, it will not meet the environmental case of the product salt spray test, which will waste manpower and material resources, and can not get the correct product corrosion resistance data, and even lead to product quality judgment. There should be no loss.
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.

Measures to ensure the quality of the salt spray test chamber
1. Vigorously carry out the appropriate work of the standard method for determining the basic parameters of the salt spray test chamber, so that the user can increase the importance of regular calibration of the equipment.
In order to make the salt spray test chamber in use really play a role in ensuring the accuracy of the salt spray test of the product, the State has promulgated the GB5170-85 standard in 1985, which compares the basic parameters of the salt spray box. Detailed regulations. Although the standard has been promulgated for many years, it is reported. Many users still don't know what the standard is. Some user parks do not know the correct method for the verification of the salt spray test chamber, but only periodically according to the metering requirements of the instrument. In doing so, the quality of the salt spray test chamber cannot be guaranteed, and the instrument control system is easily damaged. To solve this problem, some enterprises with strong technical strength should periodically check the salt spray test chambers used according to the standard requirements. The technical supervision department should use its own worries and actively organize standard publicity classes. Salt fog test chamber users understand the standard method of salt fog sugar rate parameter verification method. And Zui finally used his own strength to carry out regular sand test on the salt spray test chamber.
2. The technical supervision department will come forward to carry out supervision and inspection of the quality of the use of the salt spray test chamber.
The salt spray test chamber is an important equipment for checking the adaptability of salt spray environment. Only when the accuracy of the test of the equipment is ensured can the correct judgment of the corrosion resistance quality of the product be made. Therefore, it is necessary for the technical supervision department to conduct regular inspections on the quality of the salt spray test chamber.
The quality inspection of the salt spray test chamber is different from the normal product measurement and quality inspection. It requires the inspection unit to send the instrument to the factory to check the main basic parameters of the salt spray test chamber. The purpose of the inspection is to Ensure the quality of the equipment is used instead of simply judging that the equipment meets the non-compliance requirements. At the same time, after checking out the problems existing in the salt spray test chamber, the performance of the salt spray test chamber should be adjusted according to the situation. Retire or stop using. Therefore, it has higher technical requirements for the inspectors. It not only requires the inspectors to be familiar with the verification methods and testing instruments of the salt spray test chamber, but also should understand the working principle and performance of each type of salt spray test chamber in order to be competent in salt. The need for quality inspection work in the oligo case.
Judging from the nature and working characteristics of the rhyme inspection in the salt spray test chamber, it is more appropriate for the comrades in charge of the product environmental test and equipment inspection work to be engaged in this work, and can combine the characteristics of technical supervision to force Users of salt spray test chambers pay attention to the quality inspection of the salt spray test chamber to ensure the accuracy of the salt spray test.
3. Strengthen the salt spray test chamber users and production plants, so that both sides can improve the technical level and promote the development of salt spray test and salt spray test chamber performance level.
Judging from the survey of some salt spray test chambers, many users have a good understanding of the working principle of the salt spray test chamber used. Therefore, due to improper use and maintenance, there are many cases where salt spray sugar is released. Some salt spray test chambers have minor problems, and users do not know how to eliminate them. To solve this problem, it is necessary to strengthen the user's understanding of the working principle and usability of the salt spray test chamber, and improve the user's maintenance and repair technology level of the salt spray test chamber used.

icacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
