Acceptance Test Procedures (ATPs)
A sample piece of gel provided with every lot purchased by new buyer(s) or if any new product introduced for self-authentication at buyer's end. These are sequential and destructive testing for tester sample provided (not to be done on actual product purchased) as per instructions/ procedures given below.
Moisture Resistant
Dip the complete product in the water filled testing container and keep it for 1 hour to check impact by squeezing it and then wipe it. Is there any absorption of water or not?
Cold Tolerance Testing
Take the sample piece and keep it in the refrigerator (ice making section) for 1/2 hour, remove the sample, check its integrity after wiping it with clean cloth.
Keep it at room temperature (~25 degree C) for 10 min prior to next testing.
Clean Test
Dip the sample in known detergents / mild soaps, remove it after a while, clean with clear water, keep it under running fan. Record the observations - time to self dry up; any change in its appearance or color; water retention or not. Wipe it prior to next testing procedure. You can also disinfect the sample with disinfection agents laid down in instructions to care.
Resilience Test or Weight Bearing Capacity
2000 pounds of weight to be placed on the sample piece (vertically downwards, as maximum load will be placed on the product). Remove it carefully after 15 min and note the observations: (a) time to achieve normal shape; (b) distortion on the surface (Repeat the process 05 times and check the observations).
Elastomeric Behavior or Stretch ability Test
To test the intrinsic property of elastomeric cushioning, hold the dried sample from both ends and stretch it twice its length (check whether it reached twice its length), slowly remove the tension induced (check how much time it will take to recover it to original shape). Ask your friend or colleague to hold two ends of the piece while you hold the other two and expand it slowly (check your observation, whether it expands extensively or not), remove the tension slowly and note how much time it will take to come back to normal state.
Prick Test
To check the robustness and whether it leaks or not. This is destructive testing and should only be conducted once all the above-mentioned tests are completed. Take an pointed pin with sharp end and pierce it at the centre of the sample piece by vertically downward action, repeat it twice at 02 different positions. Check whether the sample leaks at any time.
Burn Test
Please read safety instruction before conducting this test. Hold carefully the pricked sample (previous test) in your left hand and burn the sample from the opposite side (Observe the type and color of smoke, melting rate and residue falling on the ground). Remember it would be extremely hot to touch the melted gel and you need to shut the burning within few seconds of burning otherwise complete sample will be burnt in no time. Don't perform this procedure on silicon gel or latex containing sheet without any mask as a black toxic smoke and / or powdery residue ( in case of silicone) will be observed.
Compare your results (as given above)
Self Authenticate your test sample as Medigel (Viscoelastic Gel with Covid Coat+) should exhibit following properties:
(1) Moisture Resistant : Completely Resistant
(2) Cold Tolerance Testing: Tolerant
(3) Clean Test: Yes, it will pass
(4) Resilience Testing: Extreme
(5) Elastomeric Behavior Testing: Excellent
(6) Prick or Leak Test: Don't Leak
(7) Burn Test: White smoke with no odor, burns like candle or true gel.
