Surface Insulation Resistance (SIR), as defined by IPC, is the electrical resistance of an insulating material between a pair of contacts, conductors, or grounding devices that is determined under specified environmental and electrical conditions.In respect to the world of printed circuit boards (PCBs) and printed circuit assemblies (PCAs), SIR testing—also commonly referred to as Temperature Humidity Bias (THB) testing—is used to evaluate a product’s or a process’ ability to resist “failure” by means of current leakage or an electrical short (i.e., dendritic growth). SIR testing is typically performed under elevated temperature and humidity conditions—such as 85°C/85% RH and 40°C/90%—with periodic insulation resistance (IR) measurements obtained.

Campbell Scientific, Inc.
Campbell Scientific offers two types of leaf wetness sensors to measure the wetness of leaves: surface contact and electrical resistance. Surface contact sensors measure the electrical resistance of a water film on their surface. Electrical resistance sensors imitate the characteristics of leaves and measure the dielectric constant of their upper surfaces.

PRF-911PT -
Prostat Corporation
The PRF-911 Concentric Ring is to be attached to the PRS-801B Resistance System included in this Packaging Test Kit. This system will also give you surface resistivity by multiplying the surface resistance measurement in ohms by 10 to obtain surface resistivity in ohms/square. The PRF-911PT meets requirements from ANSI/ESD STM11.11, ANSI/ESD STM11.12 snd IEC 61340-2-3. It will also approximate surface and volume resistivity measurements per ASTM D-257.

Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.

ESD MANUFACTURING & SUPPLY
The ESD LCD SURFACE RESISTIVITY METER provides everything necessary to test work surfaces using the procedure outlined in the EOS/ESD-S4.1 standard. This test kit makes testing surface resistance easy – simply place the weights attach the cables, switch to the correct voltage and press the button to read resistance directly on the meter. The meter incorporates parallel probes on the bottom of the unit which allows the user to make surface resistivity measurements. The parallel probes allow for quick and easy testing of a variety of surfaces and materials, without the use of the five pound electrodes
