Mendeleev organized his periodic table in horizontal rows in order of... Nonmetals are to the ________ of the zigzag line. Typically, the end-use environment would not cause failures. In addition, the energy levels are very low (test current is measured in mA) and performed under room temperature conditions. IPC will be enacting further security features for the exams in the coming months. When the voltage is first applied, the current usually peaks and then, due to humidity that might be dried out by the energy of applied voltage and something called "dielectric absorption", it trends lower over time.

Cirris worked with other WHMA and IPC members in creating the test section (section 19), which became the major change in the A-620 standard (Rev A released in July of 2006). Originally released in 2002, the IPC/WHMA-A-620 has become the industry standard against which to measure quality. When tested, the voltage used is in the thousands of volts. This question most often arises from those doing work under military contracts where interpretations for different requirements may conflict. These tables are from IPC/WHMA-A-620 Revision B Chapter 19 Testing. With clearance distances (air gaps or creepage) ≥2 mm [0.079 in] and not coaxial/biaxial/triaxial assemblies: Voltage Level: 1500 VDC or equivalent peak AC voltage, Max Leakage Current: 1 mA, Dwell time: 1 Second.

Table 19-4 Dielectric Withstanding Voltage Test (DWV) Minimum Requirements (Proposed by Cirris): Note 2: Voltage Level is applicable when clearance distance tested is ≥0.58 mm [0.019 in] an agreement between the User and Manufacturer to de-rate these test levels would be expected. However, the need for a good HV test increases as the spacing gets smaller. With creepage distance >2 mm the likelihood of finding near-shorts with high voltage tests was not thought to offset the cost of the more rigorous HV tests that would be required. In Class 2, just as in Class 3, small creepage distances can justify a reduction in the voltage applied for the high voltage test.
