QUALITY CONTROL ACCORDING TO EUROPEAN NORM EN ISO 4074
During the manufacturing process, condom samples are drawn from each batch by statistical sampling plans to be tested in the Quality Control Laboratory in accordance with Norm EN ISO 4074 – NATURAL RUBBER LATEX CONDOMS.
This Norm specifies the technical specifications that the condoms have to fulfil to guarantee the quality of the product.
· Dimensions: Length and width.
· Tensile Properties:
Test piece of condom is cut and placed in the tensile testing machine. The test piece is stretched until it breaks.
The Force (Newton’s) and Elongation (%) at point of breakage of the test piece are measured and registered.
· Bursting volume and pressure test:
A specified length of the condom is inflated with air, and volume (dm3) and pressure (kPa) at constant speed required to burst the condom are recorded.
· Freedom from Holes Water Electronic Test:
The condoms are screened electrically to detect holes. The condom is filled with water and is submerged in water where an electrical current is applied. A condom which has no hole acts as an insulator and allows no current to flow in an electrical circuit.
· Color Fastness:
The colored condoms are tested to assess that there is not pigmentation loss.
· Packaging and labelling:
The individual container and consumer pack are tested to ensure they fulfil the current Norm specifications.
