Frequently Asked Questions

We've compiled a list of our most Frequently Asked Questions for easy reference to many testing questions and concerns. If your question isn't answered here, please contact us or call the office at (502) 333-0510.

How soon will my materials be tested?

ArcWear conducts arc flash testing for one week during each month at the Kinectrics High Currency Lab in Toronto, Canada. Items are tested in the order they are received. For highest probability of testing during scheduled test dates, please send materials before the stated deadline. Visit our home page for currently scheduled testing dates.

Small scale tests (ASTM D6413 Vertical Flame) are conducted on a very frequent basis. Contact Stacy if you have questions in regards to testing and/or deadlines.

When will I get my arc test results?

Arc test results are reported to the customer in two phases. Upon test completion, initial results are sent via email.

Within three weeks from test completion, results will receive a second email with the final test report. Included in the final email report will be a username and password allowing access to raw test data, photos, video and final reports from testing at

How do I get started?

In order to send materials for testing, please contact our office to request instructions and arc testing forms. Please contact us or call (502) 333-0510 and our staff will be glad to assist you.

What materials should I send for testing?

Materials require different methods of preparation depending on which type of test is requested. Various measurements are determined by which test is necessary for your product and which measurement system is used by the customer.

  • For single layer testing: 6 meters/yards, width 1.5 meters/60 inches
  • For multi-layer and rainwear testing: 7 meters/yards, width 1.5 meters/60 inches

Garment Evaluation, F2621, IEC 61482-1 Method B

  • Single Layer Garment - Two garment samples - Size Large
  • Multi-Layer Garment - Three garment samples - Size Large

Fall Protection Harness, F887

  • Eight harnesses

Hoods, Goggles and Face Shields, F2178

  • 28 samples with at least six hard hats

Gloves - Size 10 or Large

  • Rubber: 20 pairs
  • All other: 15 pairs

Full ASTM F1506 Testing

  • 12 yards of material

How are fabric/garments washed?

Textiles and garments should be washed before cutting. ASTM F1959 and ASTM F2621 require three washings and one dry. IEC 61482 requires 5 washings and one dry per ISO 6330. Customers who are cutting their own fabric should do so after washing according to these specifications as outlined.

ArcWear provides this service using AATCC Method 135 or ISO 6330, as determined by the test standard used. Contact us for pricing on non-standard wash cycles or wash quantities.

How should fabric panels be cut for arc testing?

After laundering, textiles are cut to the specifications provided below. ArcWear provides this service for a nominal fee. If you choose to prepare samples in house, materials must be laundered according to the standards described above before they are cut. The laundered materials must be cut to the following specifications:

  • Measurements: 66 cm x 30 cm or 26 inches x 12 inches
  • The fabric should be cut along the selvage edge

The quantity of panels necessary for testing is determined by which type of test is being performed. Quantities are listed for Single Layer and Multi-Layer testing as follows:

  • Single Layer Test: 28 panels
  • Multi-Layer Test: 31 panels
  • Rainwear Test: 37 panels

Does ArcWear perform all testing for ASTM F887?

ArcWear only performs the arc flash testing portion of the tests. After the arc flash testing is complete, a drop test must be performed. ArcWear can arrange for this testing through an ISO 17025 accredited testing lab, or we will return the tested harnesses to the manufacturer to make arrangements for the drop test.

What are the requirements of ASTM D6413?

ASTM D6413 is a test method that has no requirements within itself. This method is commonly cited by specifications that do call out requirements; for example, ASTM F1506, ASTM F1891, NFPA 2112, etc. The following requirements are designated for ASTM F1506 and F1891 evaluations: for all fabrics (knitted, woven, and nonwoven), the maximum char length is 152 mm and the maximum afterflame is 2 seconds. Melting and dripping is not permitted.

What is the difference between testing methods for ASTM F1959 and ASTM F1891?

The testing method is the same for both ASTM F1959 and ASTM F1891. However, additional testing is required for ASTM F1891 for rainwear and laminates.

  • ASTM F1959: either the ATPV or EBT is determined (whichever is lower)
  • ASTM F1891: both the ATPV and EBT are determined and the panels are also tested at 2 times the ATPV value to check for melting and dripping.

Where should I send the materials for testing?

Textiles, garments and gloves come to the ArcWear office. Hoods, face shields, goggles and harnesses are shipped directly to the testing lab.

Textiles, Garment and Gloves should be shipped to:

3018 Eastpoint Parkway
Louisville, KY 40223
United States

Hoods, Face Shields, Goggles and Harnesses should be sent to the lab:

Kinectrics Inc.
Attn: Andrew Haines/Hugh Hoagland
800 Kipling Ave, Bldg KL
Toronto, Ontario M8Z-5G5

Materials Shipping Preparation

When you prepare the documentation for shipping, make the value of the items low and mark that they are samples for destructive testing that have no commercial value. Please ship DDP (Delivered Duty Paid). When shipping from outside the country, indicate "samples for destructive testing ONLY." Any applied customs/duty charges are the responsibility of the customer.

What is Arc Flash Testing?

Arc flash testing is the process of determining the arc rating for materials and equipment to be used in electrical hazardous environments. Arc ratings are important in assisting companies and manufactures in staying compliant with OSHA regulations and in keeping their workforce safe in a potential arc flash situation. Arc flash testing allows safer choices of PPE for your hazard and minimizing injury.

Whas is the Importance of Arc Flash Testing

Arc flash testing provides the information necessary to protect workers in the case of an arc flash event. Knowing the response of fabric in an arc flash event can be the difference between minimal and critical, even fatal injury.

Arc Rated vs Flame Resistant

Do you know the difference Between Arc Rated (AR) and Flame Resistant (FR) clothing? All clothing with an arc rating (AR) is flame resistant (FR), but not all FR clothing has an arc rating. Get the facts about AR clothing verses FR clothing from ArcWear.
