SIST EN 14653-2:2005 is the Slovenian adoption of EN 14653-2:2005, published by SIST and CEN. It specifies how to assess manually operated hydraulic shoring systems for groundwork support by calculation or by test, so manufacturers, test laboratories and conformity assessors can check products covered by EN 14653-1.

What does SIST EN 14653-2:2005 specify?

SIST EN 14653-2:2005 gives methods for assessing the conformity of manually operated hydraulic systems for groundwork support whose performance is specified in EN 14653-1. It is an assessment standard, not a product specification standard.

The document is organized into clauses for scope, references, terms and symbols, requirements, assessment by calculation, and assessment by testing, followed by an informative example in Annex A and a bibliography.

Clauses 1-4	Scope, normative references, terms and definitions, symbols
Clause 5	General requirements and what must be assessed
Clause 6	Assessment by calculation
Clause 7	Assessment by testing, including material checks and test procedures
Annex A	Informative statistical example for evaluating test results

What are the key requirements of SIST EN 14653-2:2005?

The core rule in SIST EN 14653-2:2005 is that all systems, components and their instruction manuals are assessed against EN 14653-1. In practice, the assessment must cover the actual product and the information needed to use it safely.

Assessment basis

Clause 5 requires assessment under the structural configurations that create the most severe loading effects specified by the manufacturer. It also requires the loading configurations named in EN 14653-1. This matters because the system must be checked in the combinations of parts and loads that are most demanding in real use.

Calculation route

Clause 5.4.1 allows calculation in accordance with ENV 1993-1-1 for steel or ENV 1999-1-1 for aluminium. Cast iron is treated using ENV 1993-1-1, subject to EN 14653-1. Clause 6 adds that internal forces and moments are to be found by elastic analysis only, with no plastic redistribution, and that second-order effects must be included. For a reader, this means the structural check is based on conservative elastic behaviour and must account for deflection effects.

When testing is required

Clause 5.4.2 requires structural testing when no suitable calculation model exists, when the model is uncertain, or when EN 14653-1 requires verification by test. The document specifically calls for testing of:

• axial compressive resistance of hydraulic waler struts with spigot type extension bars
• axial compressive resistance of rams and struts with restraint conditions outside those described in EN 14653-1
• mechanical locking mechanisms on waler struts
• non-proprietary valves

Test materials and preparation

Clause 7.2 requires material properties to be taken from 3.1.B certificates to EN 10204 where available, with hardness checks on 20 % of the components using EN ISO 6506-1. If certificates are not available, tensile testing to EN 10002-1 is used to establish yield strength, tensile strength and fracture elongation. This means the assessor has to confirm not only the geometry but also the material identity.

Structural and functional tests

Clause 7.3.1 sets the test procedure for hydraulic waler struts and rams: force-controlled compression testing, representative end conditions, monitoring of axial and lateral deflection, and test setups that reflect the declared operating range. Clause 7.3.3 covers locking devices, including a hold-and-failure simulation and a minimum duration for load retention. Clause 7.3.5 covers non-proprietary valves, including pressure testing up to the stated limit. Clause 7.4 then sends the evaluation of characteristic resistance to EN 12811-3.

What terms does SIST EN 14653-2:2005 define?

SIST EN 14653-2:2005 uses the terms and definitions from EN 14653-1, and several of them are central to the test methods.

• Hydraulic bracing frame - a prefabricated frame adjusted by hydraulic or combined hydraulic and mechanical means to support excavation sides.
• Hydraulic waler frame - a prefabricated support frame using hydraulic adjustment in the same excavation-support function.
• Hydraulic waler strut - a strut used in the system whose compressive resistance is one of the main test topics.
• Ram - a hydraulic component whose compressive performance is assessed in the same way as struts.
• Mechanical locking device - the device that must retain load if the hydraulic function fails.
• Non-proprietary valve - a valve type that is tested for burst or leak performance against the stated pressure limit.
• Characteristic resistance - the resistance value derived from test results for use in conformity assessment.

Who uses SIST EN 14653-2:2005?

SIST EN 14653-2:2005 is used by manufacturers of excavation support systems, test laboratories, design engineers and conformity assessors. It is also relevant to temporary works specialists, quality managers and buyers who need evidence that a manually operated hydraulic shoring system has been checked by calculation or test.

The standard is aimed at groundwork support and underground works, especially equipment used with sheeting in excavations and with supplementary items such as knee braces and intermediate hydraulic bracing struts.

Which standards are used with SIST EN 14653-2:2005?

• EN 14653-1:2005 - provides the product specifications and performance requirements that this part assesses.
• EN 12811-3:2002 - provides load testing provisions and the statistical evaluation method used for test results.
• ENV 1993-1-1 - provides steel design rules used for calculation, and its Annex Y is referenced for certain bending-plus-axial-load tests.
• ENV 1999-1-1 - provides aluminium design rules used when the system is made of aluminium.
• EN 10002-1 - provides tensile testing for material properties when inspection certificates are not available.
• EN 10204 - provides the inspection document type 3.1.B used to support material verification.
• EN ISO 6506-1 - provides the Brinell hardness test used to confirm declared materials.
• EN 12811-2 - is listed as a related part on information about materials.

What does the SIST EN 14653-2:2005 document contain?

Clause 7 contains the main test procedures for compression resistance, locking devices and valves, including the test setup, loading rate, specimen preparation and acceptance conditions. The document also gives the rules for choosing between calculation and test, and for deciding which configurations must be checked.

Annex A provides a worked statistical example for test-result evaluation. It shows how compression test results are transformed, averaged and converted into characteristic resistance values, using the equations referenced in the annex. This is useful for laboratories and assessors that need to turn raw test data into a declared resistance value.

Introduction
Manually operated hydraulic shoring systems comprise prefabricated equipment to support sheeting
to the sides of excavations. This document covers two types of equipment whose adjustment is by
hydraulic or a combination of hydraulic and mechanical means:
a) hydraulic bracing frames;
b) hydraulic waler frames.
A variety of components exist which when assembled forms a full system. The instruction manual
provides all the necessary information in the safe use of the systems.
The prefabricated components are used to make frame assemblies of different dimensions and
structural capacities.
This equipment is frequently used in conjunction with supplementary equipment, e.g. knee braces and
intermediate hydraulic bracing struts.
