What is ASTM testing method?
ASTM test methods are petroleum industry standards, accepted worldwide for quality and reliability. ASTM test methods for petroleum and refined products include: Petroleum and Petrochemical Test Directory. ASTM Tests for Petroleum, Fuels and Petrochemicals.
What is ASTM C871?
ASTM C871 : Standard Test Methods for Chemical Analysis of Thermal Insulation Materials for Leachable Chloride, Fluoride, Silicate, and Sodium Ions.
What is the importance of insulation test?
Such tests are useful for checking the quality of insulation, not only when a product is first manufactured but also over time as the product is used. Performing such tests at regular time intervals can detect impending insulation failures before they occur and prevent user accidents or costly product repairs.
What is the purpose of ASTM?
The American Society for Testing and Materials (ASTM) is an internationally recognized body that develops and delivers voluntary consensus standards designed to improve product quality, make products safer, improve international standardization and therefore facilitate trade.
Who conducts ASTM testing?
ASTM Test Methods Performed by SGS-IPS For many tests, SGS-IPS follows the American Society for Testing and Materials (ASTM) test method standards.
How do you use insulation tester?
If you are testing insulation resistance to ground, place the positive probe on the ground wire or the grounded metal junction box and the negative probe on the conductor or terminal. Energize the Megger for 1 minute. Read the value of the resistance at the end of the minute test and note it in your table.
What is HV test?
High Voltage testing is usually performed to qualify the device to operate safely during rated electrical conditions, a way to check the effectiveness of its insulation. The objective sought during the high voltage testing will determine the type and amount of voltage applied and the acceptable current flow.
What does ASTM stand for standards?
American Society for Testing and Materials
Currently known as ASTM International, “American Society for Testing and Materials”, ASTM is a developer of international voluntary consensus standards.
How do you read ASTM standards?
When reading an ASTM standard, you will usually see two numbers after the standard, like A449-14. The last two numbers signify the year the standard was updated.
