Are Your Rubber Goods in Compliance?
Regular inspection and testing intervals are designed to keep users safe. Rubber can become compromised through regular use, age, exposure to sharp objects, dirt, oils, petroleum-based products, environmental fluctuations, and improper storage. For these reasons, regular visual and electrical inspections are mandated by ASTM and OSHA.
*OSHA regulations require electrical testing of rubber insulating equipment prior to the first use and periodically thereafter. Initial tests are referred to as a proof-test or acceptance test. These testing standards reference federal OSHA regulations and ASTM standards. Please note: State OSHA regulations and/or company regulations may have even more stringent testing intervals.
Post-Testing Process
Certification and Stamping
- Items are stamped certified with the name of the company certifying the goods, testing voltage, and date stamp (Wesco can provide “Date of Test” or “Expiration Date” based on customer parameters)
- Rejected items are clearly stamped as “Visual Test Failure” or “Electric Test Failure.”
- All electrical test failures are rendered useless prior to being shipped back to the customer if a return is requested
Protecting
- Items that have passed testing are packaged in sealed poly bags
- Plastic containers are recommended for shipping and storing purposes
- Failures can be used for training purposes, further review, monitoring, and tracking

Companies Should Protect Their Rubber Goods with Daily Visual Inspections
Your first line of defense in preventing an accident.
Daily visual inspections are required by ASTM F1236-96, which outlines 24 types of irregularities to look for during inspections. Making regular visual inspections is crucial for safety. The use of damaged goods puts the user in harm’s way. Some damage is not easily visible, requiring inflation or rolling to expose damage such as dry rot, pin-sized holes, nicks, cuts, etc.
