Contact | □ | Have precautions been checked in the case of switching with both high | |||
and low loads by the same contact? |
| ||||
reliability | □ Doesn't heat dissipation occur under low temperature? | ||||
Contact | □ Has transient state of contact resistance been considered? | ||||
|
|
|
|
| |
resistance | □ Are contact voltage and current 6V 1A or higher? | ||||
Operating sound | □ Are there any problems regarding operating sound of relay? | ||||
Mechanical | □ Are there any problems regarding abnormal weak noise of relay? | ||||

|
□Is temperature, humidity, atomosphere pressure within the range of use?
| □ | Have precautions been checked in the case of switching under high | ||
| humidity? |
| ||
| □ | Is the ambient environment free from particles, dusts, sulfidizing gas, | ||
| organic gas? |
| ||
Use | □ Is the ambient environment free from silicon? | |||
environmental | □ | Is the ambient environment free from | ||
condition | ||||
such as speaker? |
| |||
| □ | Are the ambient vibration and shock below the relay's vibration and | ||
| impact characteristics? Also, is there no resonance after the relay is |
| ||
| □ Isn't there a risk of freezing and dewing of relay? | |||
|
|
| ||
| □ Isn't there a risk of water or oil adhesion? | |||
Mounting | □ | Doesn't vibration or shock cause poor connection between a relay and a | ||
connector? |
| |||
| □ | Have precautions been checked for operating of flux applying and | ||
| automatic soldering? |
| ||
| □ Have precautions been checked for cleaning operation of print board? | |||
PCB mounting | □ | Isn't glass shot performed for flux cleaning? (Particle of the glass may | ||
get inside the relay and cause operation failure.) |
| |||
| □ | Does significant warping of print board occur, which applies a force on a | ||
| relay teminal and changes the relay characteristics? |
| ||
| □ | Isn't the unused terminal cut? (Applied force on terminal can change the | ||
| characteristics.) |
| ||
Soldering | □ Any strong forces such as terminal clinch are not applied at attaching. | |||
| □ | Aren't load, shock, or vibration which is out of the allowable range | ||
Storage, | applied during transportation? |
| ||
□ Are temperature and humidity within the allowable range? | ||||
transportation | □ Is the ambient atomosphere free from organic gas and sulfidizing gas? | |||
| ||||
Product | □ Aren't dropped or fallen tube packages used? | |||
