Test intensity refers to the amount of rigor that can characterize the various loads that packages may encounter in the circulation environment. It is an important part of packaging testing. The magnitude of the magnitude of the factors to be determined for each test depends mainly on the factors causing the hazard, the stress resulting from the hazard and the ability of the selected test project to simulate or reproduce the hazards of these stresses, and the safety of the package to be considered second. Reliability.
The factors that need to determine the magnitude of each test are the following items:
1 temperature and humidity control test: temperature, relative humidity, time, pre-drying conditions (if necessary).
2 stacking test: load and its duration, temperature and relative humidity, the number and status of test samples.
3 Vertical impact drop test: drop height, number of impacts, temperature, relative humidity, number and condition of test samples.
4 Horizontal impact test (oblique impact, pendulum impact test): horizontal acceleration, number of impacts, impact surface, additional obstacles (if required), pendulum mass, temperature and relative humidity, number and condition of test samples.
5 Sinusoidal vibration test: frequency (fixed frequency, variable frequency), acceleration or displacement amplitude, test duration, additional load (if required), temperature and relative humidity, number and status of test samples.
6 Pressure test: Maximum load (predetermined value), platen movement speed, temperature and relative humidity, number and condition of test samples.
7 Low-pressure test: pressure and its duration, ambient temperature, and the number of test samples.
8 Stacking test using a press: the applied load and its duration, temperature and relative humidity, the number and status of test samples.
9 Spray test: the amount of spray water and its duration, the number and status of test samples.
10 Rolling test: number of scrolls, number and condition of test samples.
Different test items have different strength values. It is divided into two basic values: test strength and test intensity. The former is based on the purpose of standardization and serialization, and is based on the general distribution process and the typical weight and size of the package based on the amount determined, only the macro instructional significance; the latter is combined with specific product characteristics, specific circulation conditions, If the correction is made to the basic value, if it is not corrected, it will also be the final value of the test intensity, which is also used as the final test strength value for the test. Determine whether the sample is qualified or not, based on the strength of the final value.

Concealer can be regarded as a kind of foundation. The difference is that concealer has better covering power than ordinary foundation, and it fits the skin better, making it lasting and not easy to take off. Everyone's face will have blemishes of this kind. Applying concealer can make your face smooth and detailed again. There are usually three types of concealer: liquid, cream and stick.
If the concealer is applied too lightly or too densely, it will make the makeup look unnatural. Therefore, you should choose different concealers according to your skin type to make your skin appear healthy. Paste and strip-shaped concealers provide better coverage, but are more difficult to operate. Concealers with low coverage capabilities can make makeup look natural because of their refreshing texture. Concealers are generally solid, but the viscosity varies. According to your own needs, you can choose products that are used in a large area or used locally.
Concealer has many functions, such as covering up acne marks, reducing spots or partial dullness, and reducing dark circles. Lightweight or dense concealer will make makeup unnatural, so choose a color similar to your skin tone.
Start using it in the form of small dots. Use your ring finger to apply a solid or lotion-like masking cream directly on your face. For hard-to-reach places, use a sponge block or an inclined brush to apply. Foaming concealer usually leaves streaks on the skin, so before using it, you should smooth it on the back of your hand and use a soft brush to evenly spread the color of the collar.
