This International Standard establishes general principles regarding the procedure used in the construction and quality assessment of butt fusion jointing of polyethylene (PE) piping system components specified in accordance with relevant ISO standards. These components are installed in accordance with the relevant codes of practice, national regulations or industry guidance. Specifically, this International Standard specifies three butt fusion jointing procedures for PE pipes and fittings. These are:

 single low-pressure fusion jointing procedure;

 dual low-pressure fusion jointing procedure;

 single high-pressure fusion jointing procedure.

This International Standard takes into consideration the materials and components used, the fusion jointing procedure and equipment and the quality assessment of the completed joint. It may be applied in conjunction with appropriate national regulations and standards.

NOTE 1 The references for these procedures are given in the bibliography[1][2][3][4]. Single low-pressure fusion jointing procedure is derived from multiple procedures and agreed by experts, given in the bibliography [1][2].

NOTE 2 The three procedures detailed in this standard are based on those most commonly used. It is not the intention that one or more of these procedures should be used to replace well established and verified industry based procedures.

This document is applicable to the execution, testing and monitoring of geotechnical grouting work.

Grouting for geotechnical purposes (geotechnical grouting) is a process in which the remote placement of a pumpable material in the ground is indirectly controlled by adjusting its rheological characteristics and by the manipulation of the placement parameters (pressure, volume and the flow rate).

The following principles and methods of geotechnical grouting are covered by this document:

• displacement grouting (compaction and compensation grouting);

• grouting without displacement of the host material (permeation, fissure/rock grouting, bulk filling).

The principal objectives of geotechnical grouting are:

• the modification of the hydraulic/hydrogeological characteristics the ground;

• the modification of the mechanical properties of the ground;

• the filling of natural cavities, mine workings, voids adjacent to structures;

• inducing displacement to compensate for ground loss or to stabilize and lift footings, slabs and pavements.

Specialized grouting activities, generally associated with structural and/or emergency works, are not covered by this document.

The execution, testing and monitoring of jet grouting work is not covered by this document and is covered by EN 12716.

In the fifth paragraph, last sentence delete the final punctuation of the third item and add the following text:

";

— core drilling machines on sIn tand covered by EN 12348;

— hand-held machine (in particular machines covered by ISO 11148-5"

In the sixth paragraph, first sentence, replace "will conform to the requirements specified in this drilling and foundation equipment" with "is covered by this".

 

This European Standard specifies the common safety requirements for drilling and foundation equipment.

Part 1 of this European Standard deals with the significant hazards common to drilling and foundation equipment (see Annex A), when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (transport, assembly, dismantling, equipment in service and out of service, maintenance, moving on site, storage, disabling and scrapping).

NOTE 1 The requirements specified in this part of the standard are common to two or more families of drilling and foundation equipment.

This document gives safety requirements for all types of drilling and foundation equipment and is intended to be used in conjunction with one of parts 2 to 7. These machine specific parts do not repeat the requirements from part 1 but supplement or modify the requirements for the type of drilling and foundation equipment in question.

For multipurpose machinery, the parts of the standard that cover the specific functions and applications are used, e.g. a drilling machine also used as a piling machine will use the relevant requirements of FprEN 16228 parts 1, 2, and 4.

The following machines are excluded from the scope of this standard:

 tunnelling machines, unshielded tunnel boring machines and rodless shaft boring machines for rock according to prEN 16191;

 raise boring machines;

 drill rigs used in oil and gas industry.

NOTE 2 Specific requirements for offshore applications are not covered by this European Standard.

Where a drilling or foundation equipment of fixed configuration that is not intended to be separated is assembled using a carrier based on earth-moving equipment, agricultural equipment, or a crane, then the completed assembly will conform to the requirements specified in this drilling and foundation equipment standard.

Drilling and foundation equipment within the scope of FprEN 16228 parts 1 to 6 may include interchangeable auxiliary equipment within the scope of FprEN 16228 part 7, either as an integral part of its construction or as interchangeably fitted equipment.

If drilling and foundation equipment is intended to be used in a potentially explosive atmosphere, additional requirements will need to be met which are not covered by this standard.

This European Standard, together with part 1, deals with all significant hazards for mobile drill rigs for civil and geotechnical engineering, quarrying and mining when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4).

The requirements of this part are complementary to the common requirements formulated in FprEN 16228-1:2013.

This document does not repeat the requirements from FprEN 16228-1, but adds or replaces the requirements for application for mobile drill rigs.

In this document the general term "mobile drill rig" covers several different types of machines for use in:

— civil engineering;

— geotechnical engineering (including ground investigation, anchoring, soil nailing, mini-piling, ground stabilization, grouting);

— water well drilling;

— geothermal installations;

— landfill drilling;

— underpinning, tunnelling, mining and quarrying;

— for use above ground as well as underground.

Typically, the process of drilling involves the addition of drill rods, tubes, casings or augers etc., normally threaded, as the borehole extends to depth.

NOTE 1 For machines with torque greater than 35 kNm see FprEN 16228–4 initially.

NOTE 2 The term "drill rigs" includes rigs with a separate power pack supplied by the rig manufacturer.
