we're conducting a research study related to geotextiles, thank you so much for this!

This is Very hepful video

Hello sir Can you please tell me what is difference between ASTM D1693 and ASTM D 5397 And is it correlated or not????

Good morning sir this video very helpful for test

Thank you for highly educational video!

Thank you! Very helpful video!!!

Thank You For Demonstration

😮😮😮

This video really helping me to understand this test so well. Thankyou so much

How to do this test with glass bead sir?? Can you do one more video to do this test complete set??

Thanks for your explanation.

is there another video for updated GRI-GM13 that use ASTM D8117 for measuring OIT? Thanks a lot

So if this test were to yield 120lbs, then we can assume that a wider fabric would hold 120*12lbs/foot of material ~1440lbs per ft?

Hello Mr. Koerner What is the difference between ASTM D 1693 and D 5397. I recceived a data sheet mentioning ASTM D 1693, is there a correlation between these 2 standards? Thank you.

This is great to see how this test is performed! Thanks for a great video!

Nice informative video

Thank you for your support. It helped me a lot.

Do the test results ever fail? A lab technician has told me that he has never had a swell test Fail. Is that common or suspicious?

Vry greatful video for me,.. from India ❤️❤️❤️

So perfect specially step by step subtitle, thanks a lot

非常详细的介绍，非常感谢。

how to incorporate fluid loss in calculation/consideration design of GCL as impermeable liner of dam?

Bonjour,merci pour votre vidéo c'est très intéressant; je veux savoir si vous travaillez sur la mesure de la teneur en noir du carbone des tuyaux en PEBD,

Спасибо, очень интересно было посмотреть . ASTM D4595 в 15 минутах )

Can i ask i question anybody? Comparison of ASTM D4595 and ASTM D4632

excelente

Dear Sir, Can you please share the calculation .

Very good demonstration!

Amazing job! greetings from France!

Why the grip is not completely coving the specimens width? This specimen holding can induce an unbalanced load along the specimen, which effect the value

Great and informative. Thanks for sharing your knowledge George. Got me right up to speed with ASTM D5321 and how to interpret the data.

@3:21 Error in calculation. Per ASTM D792 specific gravity is not (a/(a-b))*(.781). It should be (a/(a-b)*(specific gravity of liquid). Specific gravity does not have any units and multiplying by density will yield units.

thanks you.

Thank you very much sir. Can you please tell me why we take only the trapezoidal section only in this test ?? Why not other sections like circular or square ??

THANKS FOR THE INFORMATION

Nice video. I have one question. What is the use of the tube exiting the middle of specimen holder?

Please advise about how shall we calculate the exact dead weight details corresponding to specific foot diameter . For example, for 6.35 mm foot diameter, what shall be the dead weight calculation in grams ? What capacity weight shall we manufacturer to apply 2 kpa pressure on test sample ?

Interesting. Quite durable.

Anyone here has ASTM D792 2020

Can you share me test results like documents

Thanks

So easy even Drew Carrey can do it!

Nice

Thanks for the video! I have a few doubts, that I would like to clarify. would you kindly share your mail id?

Thanks for your this informative video. I have one question, during the calculation of the transmissivity of geocomposite under an specific pressure For calculating the applied stress , Should we follow ASTM D6364 section 10.2.2 where the cross section of the sample (supporting area) is used instead of using the total area of the sample

Hello sir,i have 1 question.i want to increace ESCR of Hdpe geomembrane,my product have 35%lldpe and 60%hdpe and 5% componds,,,do i must put HIPS or pvc to this formul?,,,

I need this for our thesis

What do you call this machine?

thank you i needed to understand the number i was looking at.

Very nice George and well done. My only comment is the improved result repeatability and accuracy with larger sized boxes vs. the smaller(ish) 10 cm by 10 cm sizes. Both work, but in this case bigger is better.
