EN 1113:2015
(Main)Sanitary tapware - Shower hoses for sanitary tapware for water supply systems of type 1 and type 2 - General technical specification
General Information
- Abstract
This European Standard specifies:
- the dimensional, leaktightness, mechanical and hydraulic characteristics with which shower hoses should comply;
- the procedures for testing these characteristics.
This European Standard applies to shower hoses of any material used for ablutionary purposes and intended for equipping and supplementing sanitary tapware for baths and showers.
This European Standard applies to shower hoses connected downstream of the obturator of the tapware.
Hoses which are an integral part of sanitary tapware (sink and wash basin mixing valves) or hoses intended to connect sanitary tapware to the water supplies are not covered by this European Standard.
Details of pressures and temperatures are given in Table 1.

Overview
EN 1113:2015 (CEN) specifies the general technical requirements and test methods for shower hoses used with sanitary tapware for water supply systems of Type 1 and Type 2. The standard covers dimensional, leaktightness, mechanical and hydraulic characteristics and applies to hoses used for ablutionary purposes that connect downstream of the tap obturator. It does not cover hoses that are integral to tapware or hoses that connect tapware to the water supply.
Key topics and technical requirements
Scope of use and classifications
- Applies to shower hoses for Type 1 and Type 2 water supply systems; Table 1 in the standard defines the detailed pressure and temperature conditions and recommended limits.
- Flow-rate classes are defined (e.g., Type 1: Class 1 and Class 2; Type 2: Class E and Class H) with clear flow-rate ranges per class to match supply conditions.
Dimensional & designation requirements
- Standard connection thread sizes and designations (e.g., G 1/2 × G 1/2 or G 1/2 × G 3/4), hose length, external sheath material (plastic/metal), nut types and cone dimensions are specified for interchangeability and correct sealing.
Materials & hygiene
- Materials in contact with potable water must not present health risks or alter water quality up to the maximum working temperature; visible Ni-Cr coatings must comply with EN 248.
Hydraulic requirements and flow testing
- Hydraulic performance and flow-rate verification procedures are described; flow-rate classes link to operating pressure ranges.
Mechanical & leaktightness testing
- Includes tensile strength, resistance to flexing (endurance), pressure resistance at elevated temperature, leaktightness after mechanical testing, thermal shock, and rotary connection performance. Detailed test apparatus, procedures and pass/fail criteria are provided.
Marking
- Permanent, legible manufacturer/supplier marking is required; full designation (thread, length, material, EN reference, class) is recommended.
Applications and users
- Manufacturers - design and certify shower hoses to meet European market requirements.
- Test laboratories - perform compliance testing (tensile, flexing, pressure, leaktightness, thermal).
- Specifiers & procurement - select hoses compliant with EN 1113:2015 for commercial and residential projects.
- Installers and maintenance teams - ensure correct hose selection for Type 1/Type 2 systems and verify marking and connections.
- Regulators & certification bodies - use the standard for national adoption and conformity assessment in CEN member countries.
Related standards
- EN 248 - electrodeposited Ni-Cr coating requirements (relevant for chrome-plated hose fittings)
- EN ISO 228-1 - pipe thread dimensions where joints are not pressure-tight (used for connecting threads)
EN 1113:2015 is a practical, test-focused standard ensuring safe, interoperable and hygienic shower hoses for European water supply systems. Keywords: EN 1113:2015, shower hoses, sanitary tapware, flow rate classes, pressure testing, leaktightness, dimensional requirements, CEN.
