Hydraulic fluid power cylinders - Dimensions and tolerances of housings for elastomer-energized, plastic-faced seals - Part 2 : rod seal housings

This document specifies the dimensions and associated tolerances for a series of hydraulic cylinder rod seal housings to accommodate elastomer-energized, plastic-faced seals used in reciprocating applications. This document does not stipulate details of seal design, since the manner of construction of seals varies with each manufacturer. The design and material of the seals, and any incorporated anti-extrusion components, are determined by conditions such as temperature and pressure. This document only applies to the dimensional characteristics of products manufactured in accordance with this document. It does not apply to their functional characteristics.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
