This document applies to all types of thermoplastics valves intended to be used for the transport of fluids.
NOTE 1 Examples of valve types tested with this method are in ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 21787, ISO 4437-4, ISO 16486-4, EN 12201-4, EN 1555-4.
It does not specify the relationship between the torque and its possible increase after valve prolonged use at specific working condition or materials wear/chemical aggression.
NOTE 2 Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358; concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closure, further information is provided in ISO 8659.

This document specifies a method to determine the total content of the 8 regulated polycyclic aromatic hydrocarbons (PAHs), see Table 1, in plastic and rubber articles by using GC-MS allowing detection at 0,1 mg PAHs/kg for plastic and 0,2 mg PAHs/kg for rubber material. Table 1 - List of PAHs ... NOTE Other PAHs compounds can also be analysed with this method, provided suitability has been proven.
