How we test and measure sex toys in a sex shop before it is launched.
Measuring the hardness of dildos and other erotic toys
Hardness of erotic toys we measure with C durometer on the scale 0-100HC. We can talk about percent hardness. Hardness sex dolls measured in accordance with the official methodology for a C durometer, which determines a thrust of 44 N (4.4 kg). Dildo and vibrator hardness we measure in contradiction with the C durometer methodology, so that the 2.5mm tip just goes into the rubber to avoid measuring the compressed rubber. It makes no sense to measure the hardness of medical silicone hard pins - always above 60HC, ie. for the body essentially completely hard (only slightly flexible, not elastic). It's different for soft liquid silicone.
Values of rubber up to 10HC according to the methodology would be about 60% harder, up to 20HC about 40%, from 40HC the deviation is small. Hardness is measured on the acorn resp. on the tip of a penis or toy, where the hardness tends to be the highest and where the indication is most important to the customer, because the tip exerts the most pressure on the tissue. A Type A durometer should be used correctly for soft rubbers, but its measurements show very low values with low resolution. E.g. where the C durometer shows 1 or 10HC, the A durometer shows 1HC. Where the C durometer shows 35-40HC, the A durometer shows about half. For values above the hardness of 50HC, the differences are reduced. So we stay with the C durometer for hard rubber, which has a higher resolution and ability and shows intuitively more corresponding values.
Human tissue reactions and in-service testing
We test the use and functionality, eg whether the harness really immobilizes or stretches, simply fulfills its purpose.
The dildos are tested for the amount of skin pull during friction. Porous PVC dildos pull quite a bit. Non-porous silicone practically at all. Exceptionally, some dildos (even in reputable stores or distributors) burn mucous membranes when injured and are not allowed to sell. Furthermore, resistance to prohibited gels for a given material and relatively extreme environment in the rectum. Most devices except condoms can be used in practice with banned gels without damaging them. Some dildos slightly deform the surface to smooth the skin or stain with stool - especially PCV and TPE dildos when using a fat / oil based gel (deer tallow).
The rectal mucosa is also very sensitive to grinding / rounding and is usually used to confirm the tactile test.
Gels are tested for drying, mucosal, condom and toy effects.

Visual and tactile control
Test of surface cleanliness, casting, edge rounding, especially of metal objects - whether they will cut the mucous membrane eg in metals. Safety of handcuffs to avoid cutting nylon eye-catchers or plucking tissue like commercially available snap hooks.
It concerns handcuffs, chains, vaginal mirrors, cock rings. It is advisable to withstand an adequate degree of stress. For example, it should not normally be possible to bend the vagina or anus sphincter.
Only by the human senses. Products with a stronger odor of plastic, perfume or other odor are not allowed on sale.
Dimensions, weight, noise
dimensions: meter, caliper (for dildos the first figure is the length, sometimes in parentheses is the insertable length. the last figure is the diameter)
weight: digital scale - net including remote control without batteries and charging accessories
Vibrators sound - about 5 cm from the phone's microphone with a high-end android in the app. Measurement at this distance corresponds to the data of the manufacturers of various products, although sometimes the values are measured meter or 10m from the device (eg for commercial refrigeration compressors). Quieter vibrators have 50-60 db, the standard is around 70 db.
Laboratory tests are not within our power. For the devices introduced, we focus on CE certified products where the presence of harmful substances should be avoided. For SM harnesses / clothing, testing for the presence or release rate of nickel is not planned in the near future as it is not a product intended for long-term wear within the meaning of the REACH 1907/2006 EC concerned.
