3 Test method試驗方法

3.1 Principle原理

The test is an alternating cycle consisting of a combination of various climatic and/or corrosion loads.
A test cycle consists of
- 4 h salt spray fog test according to DIN 50021 -SS,
- 4 h aging in the DIN 50014-23/50-2 standard climate (including cooling-off phase),
- 16 hours humid aging at elevated temperature, climate according to DIN 50017- KK (40 ± 3) °C] 99% humidity.
After 5 cycles, a 2-day rest phase takes place in the DIN 50014-23/50-2 standard climate.
該試驗是不同氣候和/或腐蝕負荷的循環變化的組合。
一個試驗循環包括
—4小時的鹽霧試驗，按DIN 50 021 - SS
—4小時標準氣候DIN 50 014-23/50-2 (包括冷卻階段)下的存放
—16小時的濕熱存放，氣候按DIN50017-KK (40±3)℃ 99%空氣濕度 ，5個循環后是2天在標準氣候DIN 50 014-23/50-2下的靜止狀態。
Using this test method, corrosion behavior under static load resulting from salt, humidity and temperature is uated.
用這種試驗方法通過鹽，濕度和溫度來評價靜態負荷下的腐性特性。
Under these defined corrosion conditions, different anti-corrosion coatings can be comparatively assessed.
在這種特定的腐性條件下，可以對不同的防腐涂層進行對比評價。
A correlation with the corrosion mechanism in actual driving operation is not necessarily possible, as the types of vehicle damage and corrosion curves are complex and are not completely covered and reflected by the changing corrosion load.
A short interruption of the test for inspection purposes and/or the removal of test specimens is permitted. Interrupting the test by changing the test program is not permitted.

3.2 Test fixtures試驗裝置

Assemblies, components and test panels can also be tested in suitable single or alternate devices. The devices must comply with the specifications in DIN 50014, DIN 50017 and DIN 50021.
結構組件、結構件和板材試樣的試驗可以在適宜的單個或交變試驗儀 器中進行。試驗儀器應符合DIN 50014，DIN 50017和DIN 50021的規定。

3.3 Body test車身試驗

Testing is performed according to Section 3.1. Examples are given in Section 3.6.
In order to carry out a specific uation of cavities, the body can be turned.
Before being initially brought into the salt spray test chamber, the body, mounted on the pivoting frame, is preconditioned in the DIN 50014-23/50-2 standard climate, and is then moved into the test chamber kept at a constant temperature.
驗過程按3.1條。示例列舉在3.6條中。
為了對空腔進行專門的評價，可以將車身旋轉。
安裝在旋轉支架上的車身在進入鹽霧箱之前應在標準氣候 DIN 50 014-23/50 -2下進行預處理，然后進入恒溫處理過的試驗箱中。

3.3.1 Salt spray phase鹽霧階段

During the test sequence with rotation, before each salt spray cycle, the body is turned about its lengthwise axis so that it is positioned as in the following sequence: 0°, 45°, 135°, 225° and 315°.
在旋轉試驗過程中，在每次鹽霧循環前要將車身沿縱軸繼續旋轉，以便使其依次處于下述位置：0°; 45°; 135°; 225°和315°的位置。

3.3.2 Standard climate aging / humid aging at elevated temperature在標準氣候下的存放/濕熱存放

During the cooling-off phase and during humid aging at elevated temperature, the body is positioned horizontally.
在冷卻階段以及濕熱存放期間，車身一直處于水平位置。

3.3.3 Repeating the test cycles重復試驗循環

After humid aging at elevated temperature is completed according to Section 3.1, the body is immediately placed in the salt spray test chamber and turned 90° in a clockwise direction to 45°, 135°, 225° or 315°, according to the respective test cycle.
在結束3.1條的濕熱存放后，緊接著將車身移到鹽霧箱中，并在可能的情況下
按各試驗循環沿順時針旋轉90°,使其依次處于45°; 135°; 225°和315°的
位置。

3.3.4 Weekend aging周末存放

The rest phase entails aging in the DIN 50014-23/50-2 standard climate, with the body in a horizontal position and placed either in a suitable garage/hall or in the test chamber.
該靜止狀態是在車身處于水平位置的情況下在標準氣候DIN 50014-23/50-2 下 在合適的地下室或大廳或試驗間中進行的。

3.4 Component test結構件的試驗

The required minimum for complete testing is 5 parts.
The components or their sections are tested in accordance with DIN EN ISO 7253 (see Section 4). Cavities must be exposed to the salt spray fog by cutting/opening of parts. If necessary,
unprotected trim edges must be covered before testing.
對于一次完整的檢驗至少需要5個零件。
按DIN 53167對結構件或其試樣進行檢驗（見第4條）。
通 過 分 離 / 打 開 空 腔 使 得 鹽 霧 能 夠 進 入 空 腔 。 試 驗 前 在 可 能 的 情 況 下 將 未 保 護 的 棱邊遮蔽起來。

3.5 uation評價

After 15, 30, 60 and 90 cycles, the specimens are uated with regard to
- Type of corrosion (coating and/or base metal corrosion),
- Form of corrosion (surface or edge corrosion),
一 Time of appearance and development of corrosion,
as well as with regard to additional changes in the anti-corrosion coating such as loss of adhesion or blistering.
Organic coatings can be uated according to DIN EN ISO 4628-1, Table 3.
