Standard conditions of the test site Standard Atmospheric Conditions for Testing 1. This standard application range, the temperature of the location where you want to implement (., Including the break-in for the test) test in the industrial, I prescribed for the standard state on pressure and humidity. humidity. However, what needs to be tested in a particular state It does not include the state of the test location. Corresponding international standard: ISO 554 -1,976 Standard atmospheres for conditioning and / or testing-Specifications IEC Publication 160 -1,963 Standard atmospheric conditions for test purposes 2. Standard state 2.1 The temperature of the temperature standard condition in the standard state, I will either 20 ℃ depending on the purpose of the test, of 25 ℃ or 23 ℃. 2.2 Humidity of the humidity standard state of the standard state is either 65% or 50% relative humidity. 2.3 Air pressure in the pressure of the standard state standard condition, and more than 86kPa 106kPa below. 2.4 Standard state standard condition, set each one of the humidity in the standard condition and temperature of the standard state under the pressure of the standard state And a state of the combined saw. It is also possible to specify only the temperature of the standard state by the remarks purpose. That the standard temperature condition its state. Reference 1. ISO 554 According to -1976, and defines three types of standard conditions for testing. The recommended standard for them The state, 23 ℃ temperature, relative humidity of 50%, has been with the pressure more than 86kPa 106kPa below. 2. IEC Publication 160 -1,963 According to, 15~35 ℃ temperature, relative humidity recommended recommended range of states to be measured 45 The standard temperature conditions as a reference for comparison 75% of each other, also defined as pressure 860~1060mbar 860~1060mbar Twenty ℃, 65% relative r elative humidity, humidity, you are pressure 1013mbar. In addition, the standard of measurement for the examination and the breakI have defined three types of state.
Remarks 1 013mbar Is 101.3kPa. 3. Tolerance of standard state 3.1 Tolerance of temperature tolerance standard state of the temperature of the standard condition, the table depending on the purpose of the test 1 to Kyu-betsu as. Remark 1 is, I will also apply to standard temperature state. Two Z 8703-1983 Table 1 Class by Tolerance ℃ Class 0.5 temperature ± 0.5 Primary temperature ±1 Grade 2 temperature ±2 Grade 5 temperature ±5 15 temperature class ± 15 To 20 ℃ temperature of standard condition 15 Grade Remarks temperature Are used only for. Note that the room temperature the temperature range of 5~35 ℃ Says. 3.2
Tolerance of humidity tolerance standard state of humidity of the standard condition, the table depending on the purpose of the test 2 to Kyu-betsu as. Table 2 Class by Tolerance% Grade 2 humidity ±2 Grade 5 humidity ±5 10 Grade humidity ± 10 20 Grade humidity ± 20 20 Grade Remarks humidity 65% relative humidity in the standard state I used only for. In addition, normal humidity humidity range of 45-85% That. 3.3
Tolerance of tolerance standard state of standard condition, the tolerance of the humidity of the standard condition and tolerance of the temperature of the standard state It is assumed that a combination of each one.
4. Temperature of the standard state, the display of the display standard state in the standard state is due to tolerance and humidity. It requires a display of tolerance If not, and will not be displayed. Example 1 : the temperature of the standard state is 23 ℃, 1 grade temperature, 50% humidity in the standard state, the class is another place of Class 5 humidity that another class Synthesis 23 ℃ or grade 5 primary · 50%, 23 ± 1 ℃ · 50 ± 5%, 23 (1) / 50 (5) Example 2 : In the case of the above, if you omit the class by 23 ℃ · 23/50 or 50% Example 3 : room temperature (5~35 ℃), humidity in the standard state and normal humidity case of (45-85%) the temperature of the standard state ( *
) Twenty Normal temperature ± 15 ℃ · 65 ± 20%, or 20 (15) / 65 (20), and normal humidity Note ( *
) In the case of either the normal humidity or ambient temperature Example 3 I conform to. Display Remark standard temperature state is due to tolerance of temperature and standard temperature state. It does not require the display of tolerance If omitted the display. Example 1 : Temperature of the standard temperature condition is 23 ℃, the class Another case of primary temperature 23 ℃ 23 ± 1 ℃ or primary Example 2 If you omit the class-specific in the case of the above: 23 ℃
Example 3 : temperature of the standard temperature condition if normal temperature (5~35 Twenty ± 15 ℃, 20 (15), or at room temperature
