83.140.50 - Seals

EN-IEC 62788-5-1 provides procedures for standardized test methods for evaluating theproperties of materials designed to be used as edge seals. When modules are constructed withimpermeable (or extremely low permeability) front- and backsheets designed to protectmoisture-sensitive photovoltaic (PV) materials, there is still the possibility for moisture to get infrom the sides. This moisture ingress pathway can be restricted by using a low-diffusivitymaterial around the perimeter of a module betwe...view more

ISO 9631:2018 specifies material requirements for vulcanized rubber seals for hot drinking and non-drinking water supply (up to 110 °C). The different seal designations specified are defined according to seal type, seal application and the requirements for a particular seal (see Table 2). General requirements for finished joint seals are also given. Any additional requirements called for by the particular application are specified in the relevant product standards, taking into account that the p...view more

ISO 3601-2:2016 specifies the housing (gland) dimensions for class A O-rings for general industrial applications conforming to ISO 3601-1, as well as housing dimensions for class B O-rings used on selected metric-dimensioned hardware, e.g. fluid power cylinder bores and piston rods. These O-rings are for use in general hydraulic and pneumatic applications without and with anti-extrusion rings (back-up rings). The dimensions of the O-rings (d1 and d2), size codes (SC) and tolerances conform to IS...view more

ISO 4633:2015 specifies requirements for materials used in vulcanized rubber seals for the following: a) cold drinking-water supplies (up to 50 °C); b) drainage, sewerage, and rainwater systems (continuous flow up to 45 °C and intermittent flow up to 95 °C).

ISO 3601-5:2015 contains the material specification of a selection of standard elastomeric materials (rubber) for O-rings used in general industrial applications. It also indicates the ability of the materials to satisfy many of the requirements associated with fluid power components. Only materials which are in universal usage are specified; other compounds are available and can be used. The required physical properties and test methods (including test specimen) should be agreed upon between eq...view more

This European Standard specifies the design, testing and marking requirements for caps and plugs used to form a pressure tight seal with liquefied petroleum gas (LPG) cylinder valves and pressure vessel valves. Sealing caps and plugs provide an additional seal for self-closing and manually operated valves. Dust caps or plugs and tamper evident seals that do not form an additional seal as part of their design are excluded from the scope of this European Standard. Cylinder valve caps and plugs may...view more

This European Standard specifies the material requirements and test methods for prefabricated elastomeric seals for use in flue liners. It also specifies the requirements for evaluation of conformity.
These seals are components in flue liners of different materials such as metal, plastic, clay, concrete.
Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards.
In the product standards, chimney products, including seals, are tested under opera...view more

ISO 5892:2013 specifies material requirements for preformed, solid vulcanized rubber structural gaskets in sealing and supporting applications for buildings.

ISO 3601-1:2012 specifies the inside diameters, cross-sections, tolerances and designation codes for O-rings used in fluid power systems for general industrial and aerospace applications. The dimensions and tolerances specified in ISO 3601-1:2012 are suitable for any elastomeric material, provided that suitable tooling is available.

ISO 16589-2:2011 establishes the vocabulary for seals utilizing sealing elements manufactured from suitably formulated compounds, based on thermoplastic materials, such as polytetrafluoroethylene (PTFE) that are considered suitable for use under low-pressure conditions.

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds, based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-3:2011 gives users of lip-type seals guidance on the careful storage and handling and proper installation of rotary shaft lip-type seals; attention is drawn to the hazards involved and ways of avoiding them are pointed out.
