Rubber materials for seals and diaphragms for gas appliances and gas equipment

Rubber materials for seals and diaphragms for gas appliances and gas equipment

This standard specifies requirements and associated test methods for vulcanized rubber materials used in gas appliances and equipment in contact with 1st, 2nd and 3rd family combustible gases. It also establishes a classification based on temperature range and hardness. This standard is applicable to materials from which are manufactured homogeneous seals and homogeneous or reinforced diaphragms.  The normal range of operating temperatures covered by this standard is 0 øC to + 60 øC. Tests are also included for applications using diaphragms within the range - 20 øC to + 80 øC and seals within the range - 20 øC to + 150 øC. For temperatures outside these ranges the user should contact the manufacturer regarding the suitability of the rubber material.  This standard includes two normative annexes for the verification that a component (finished product) was produced from a previously type tested material complying with requirements of this standard as declared by the appliance or equipment manufacturer or supplier of the component.  This standard is not applicable to silicone rubber used either above 200 mbar nominal pressure or at temperatures below 0 øC with 3rd family gases as there is possibility of condensation. This standard is also not applicable to seals and diaphragms for devices in gas transmission systems nor in such equipment used in 1st and 2nd family gas distribution systems.

Rubber materials for seals and diaphragms for gas appliances and gas equipment
SIST EN 549:2019+A2:2024

This document specifies requirements and associated test methods for rubber materials used in gas installations, gas equipment and gas appliances in contact with 1st, 2nd and 3rd family combustible gases as classified in EN 437:2018, additionally LPG, bio methane and bio LPG, in the same quality, are covered. It also establishes a classification based on temperature range and hardness. This document is applicable to materials from which homogeneous seals and homogeneous or reinforced diaphragms are manufactured.
Since the dimensions and shape of the components differ from those of standard test pieces taken from sheet material as used for type testing of the rubber materials according to this document, tolerances have been made in the requirements specified by Annex A for the components with respect to those specified for standard test pieces.
The range of operating temperatures covered by this document is –40 °C to +150 °C.
For applications with potential condensation, this document is not applicable for silicon rubber, e.g. above 200 hPa (200 mbar) nominal pressure or at temperatures below 0 °C with 3rd family gases.

Elastomeric Seals - Materials requirements for seals used in pipes and fittings carrying gas and hydrocarbon fluids
SIST EN 682:2002

This European Standard specifies requirements for elastomeric materials used in seals for supply pipes and fittings, ancillaries and valves at operating temperatures in general from - 5 °C up to 50 °C and in special cases from - 15 °C up to 50 °C, for the following:
General applications (see Table 4, type G)
a)    gaseous fuel (manufactured, natural and liquefied petroleum gas [LPG] in gaseous phase);
b)    hydrocarbon fluids with aromatic content up to 30 % (V/V), including LPG in liquid phase.
Special applications (see Table 4, type H)
Materials suitable for carrying gaseous fuels containing gas condensates and hydrocarbon fluids of unrestricted aromatic content.
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 performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design. This European Standard should be used where appropriate with product standards which specify performance requirements for joints.
This European Standard is applicable to joint seals for all pipeline materials including iron, steel, copper and plastics.
In the case of composite seals requirements in 4.2.8 and 4.2.9 apply only when the materials used for any elastomeric parts come into contact with gaseous fuel or hydrocarbon fluid.
Elongation at break, tensile strength, compression set and stress relaxation requirements for materials of hardness categories 80 and 90 apply only when they constitute that part of the seal which participates directly in the sealing function or in long term stability.
This standard is not applicable to the following:
a)    seals made from cellular materials;
b)    seals with enclosed voids as part of their design;
c)    seals with requirements of resistance to flame or to thermal stress;
d)    seals which contain splices joining pre-vulcanised profile ends.

Chimneys - Elastomeric seals and elastomeric sealants - Material requirements and test methods - Part 1: Seals in flue liners
SIST EN 14241-1:2013

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 operational conditions (e.g. temperature, pressure, mechanical load, flue gas, condensate) to relevant properties such as leakage and deformation.
This European Standard covers seals intended for use in both dry and wet conditions. Therefore all seals are tested for functioning under wet conditions.
This European Standard does not contain all the requirements necessary for chimneys with the following classification:
-   corrosion resistance class 2 concerning natural wood ),
-   corrosion resistance class 3.
This European Standard is also applicable for sealants, in case nothing else is defined. The specimens are made from the sealants, which have been brought into a practical form, cured under manufacturers' instructions. The cured sealants will fulfil the same requirements as seals.
NOTE   Cured sealants are operationally seals in application.
