Описание (английский):

ISO 6194-3:2009 describes seals utilizing elastomeric sealing elements. They are considered suitable for use under low-pressure condition. ISO 6194-3:2009 gives users of lip-type seals requirements and guidance on the careful storage, handling and proper installation of rotary shaft lip-type seals; attention is drawn to the hazards involved and ways of avoiding them.

Overview

ISO 6194-3:2009 - Rotary shaft lip-type seals incorporating elastomeric sealing elements - Part 3: Storage, handling and installation provides requirements and practical guidance for preserving the performance and service life of rotary shaft lip-type seals that use elastomeric sealing elements (suitable for low-pressure applications). The standard emphasizes hazard awareness and methods to avoid damage prior to and during installation.

Key topics and technical requirements

Storage practices

Store seals in accordance with ISO 2230 and ISO 6194-3 guidance: protect from mechanical damage, dust, grit, insects and rodents; prefer closed containers and non-work-area locations.
Avoid excessive stacking that could crush cartons or deform seals.
Storage-life guidelines (maximum, when stored per ISO 2230 and ISO 6194-3):
- Fluorocarbon (FKM): 10 years
- Polyacrylate (ACM/AEM): 7 years
- Butadiene/Acrylonitrile (NBR): 7 years
- Hydrogenated NBR (HNBR with some unsaturation): 7 years

Packaging and unpacking

Protect seals en route and in storage; unpack carefully (avoid knives/screwdrivers) and do not remove seals from packaging until ready for installation.

Handling of loose parts

Handle seal lips with care - the smallest nick can create a leak path.
Never hang seals on nails/strings or thread on wires; avoid contact of metal edges with rubber parts.
Clean only with manufacturer‑approved solvents; never use abrasive cleaners or corrosive chemicals that can swell or damage elastomers or bond lines.

Installation practices

Inspect seals before fitting; apply a light coat of agreed clean lubricant to sealing lips and, if applicable, to the rubber-covered outside surface.
Provide lead-in chamfers on shaft and housing per ISO 6194-1.
Use proper installation tools and align seals with machined surfaces to ensure squareness; avoid deforming seal case.
Use special tools (bullet-nose, soft-jig alternatives avoided) to slide seals over splines/keyways; do not use soft aluminium tools that nick easily.
If forcing press-fitted components over the running area is necessary, reduce shaft diameter in the running area by 0.2 mm.
For low-temperature assembly, restore lip flexibility by immersing seals 10–15 min in a compatible fluid ≤50 °C.
On replacement, fit a new seal and offset it from the previous wear track (use spacers or vary seal depth).

Applications and users

Applicable to engineers, maintenance technicians, procurement/specification writers, OEMs and seal manufacturers working with rotary shaft lip-type seals, especially in low-pressure rotating equipment such as pumps, gearboxes, motors and rotating housings.

Useful for maintenance procedures, quality control, vendor contracts and installation work instructions.
