TESTING
FOR YOUR SAFETY
The safety of our users is one of our shared priorities, which is why we provide them with a system allowing them to work in complete safety.
We conduct testing for this purpose, aimed at improving the quality of our products:
DITYBOX FUNCTIONAL TEST
UNDER NORMAL CONDITIONS
We carry out an initial functional test to ensure that the DITYBOX is operational when pressurised and ensure safety guarantees, by bleeding the air pressure under normal conditions of use.
NB: All our DITYBOX products are tested individually at 12 bar on a test bench in our workshops.
RESULT : NO DANGER !
It is not possible to generate a pressure surge in the DITYBOX: an air leak between 11.6 and 13 bar ensures that there is a safety zone under operating conditions. When the pressure has stabilised around 9 bar, airtightness is restored to the system: a reversible safety function !
DITYBOX RUPTURE TEST
UNDER ABNORMAL CONDITIONS
We replace the standard plastic nut with a stainless steel nut to remove our safety system and push our system to its limits. This testing is carried out under extreme and completely abnormal conditions.
By pressurising the system and preventing the excess air from escaping, we test our DITYBOX products for their rupture point.
The appearance of a bubble is observed.
WHY ?
The plastic material of the box is warped as it absorbs the rise in pressure. When it eventually ruptures, it is torn vertically: the box remains in a single piece.
DITYBOX can withstand up to 53 bar, or at least 6 times the working pressure.
DITYBOX HEAT RESISTANCE TEST
AGAINST DIFFERENT TEMPERATURES
TEMPERATURE TEST :
The DITYSPRAY system, once pressurised, was left on a hot item testing machine, with a "body" temperature of 62°C.
It remained there for 20 hours.
Result : No physical change observed.
• DROP TEST :
The box was then released from breast height, to the ground.
Result : No damage observed and operation was not impaired.
TEMPERATURE TEST :
The DITYSPRAY system, once pressurised, was left on a hot item testing machine, with a "body" temperature of 92°C.
It remained there for 30 minutes.
Result : No physical change observed.
DROP TEST :
The box was then released from breast height, to the ground.
Result : No damage observed and operation was not impaired.
TEMPERATURE TEST :
The DITYSPRAY system, once pressurised, was left on a hot item testing machine, with a "body" temperature of 126°C.
It remained there for 3 minutes.
Result : Started to melt after 3 minutes.
DROP TEST :
The box was then released from breast height, to the ground.
Result : : Showed no signs of damage and was operational: the system was still pressurised!
TEMPERATURE TEST :
The DITYSPRAY system, once pressurised, was placed in contact with a glass bottle at 400°C.
Result : Remained there for 3 minutes and 4 seconds… Then it burst, without any noise or explosion !
DITYBOX CHEMICAL RESISTANCE TEST
COMPATIBILITY, APPEARANCE, DIMENSIONS
Chemical compatibility :
Following contact with various chemicals, we assess the reactions of the plastic forming the DITYBOX.
Firstly, we assess the resistance of the box to contact with various chemicals. Our results are given below :
Resistant, minor reversible / irreversible or no weight and dimensional modification : Water, Seawater, 100% Ammonia, Benzene, Petrol, Glycerine, Milk, Diesel Fuel, Linseed oil, Olive oil, Silicone oil, Soybean oil, Mineral oil, Petroleum, Carbon sulphide, Carbon tetrachloride, Toluene, etc.
Resistant subject to reservations, significant dimensional modifications after a given time, potential irreversible modification of properties : 10% Acetic acid, Hydrochloric acid, Formic acid, Phosphoric acid, 10% Sulphuric acid, 36% Sulphuric acid, Chlorobenzene, 10% Copper salts, Trichlorethylene 20°C, etc.
Not resistant, may nonetheless be used on some occasions under certain conditions (reduced contact time) : Acetin, 40% Acetic acid, 1% Chromic acid, Methyl chloride, Phenol, Methylethylketone, etc.
Soluble subject to high levels of corrosion within a short time interval : 30% Hydrogen peroxide, Chlorinated lime
Visual Appearance :
Secondly, we observe the visual modifications of the box (such as for example bleaching, warping, or softening) in contact with certain substances, i.e. :
- Acetone (03710)
- Isohexane, Propan-2-ol, Ethanol (03702)
- Orange terpene (03712)
- Methylal (03715)
- Mineral oils (03717)
The box is tested for different contact times: Wiping with a cloth, 2 minutes, 1 hour and 70 hours.
The findings are probative given that, visually, no modification of the material was observed in contact with these substances.
Dimensions :
Finally, we observe whether dimensional modifications of the test specimens take place (associated with swelling, for example) with the various chemicals cited in the Visual Appearance section above, within time intervals between 1 hour and 70 hours.
Once again, the material shows no dimensional differences in contact with these substances.
