COMMENTARYONCLAUSE4
4.1Manufacturer/supplier
Anchor manufacturers and suppliers should provide suchinformation as is necessary for the specifier and the installer to ensure the safe selection, specification, installation, use, maintenance, cleaning, dismantling or disposal of the anchor without risk to safety or health
NOTESee Clause6fordetails of the information to be supplied. While anchor manufacturers and suppliers may provide advice, for which they should take responsibility,that does not make them the specifier in the contex of this British Standard, as they do not have responsibility for the selection of the anchor within the project.

4.2Designer
BS8539:2012
Suppliers of anchors should take care to supply anchors as ordered by customers Specifications of anchors that have been ordered should not be changed unless the change management procedure in Clause 1o has been followed and the proposed change has been approved by the specifier.
4.3Specifier
The specifier shoulddetermine the most appropriateanchorfortheparticular application, by following the selection process given in Clause 5 and using the appropriate design method forthat anchor.
4.4Contractor
It is essential that the contractor is satisfied at the time of installation of anchors that the strength of the base material is at least that assumed by the specifier in the design and selection of anchors. If not, the contractor should liaise with the specifier and await instructions.

5.3 Factors determining anchor type

fundamental to the selection of properly qualified anchors (see AnnexD, Figure D.1 and Figure D.2). Applications inwhichthefailureof any anchor supportingthefixturewill ead to its collapse are referred to as being"statically determinate (see 3.1.43),while those which have been designed with sufficient edundancy (see 3.1.36)that the failure of one anchor willnot lead to orogressive collapse(see3.1.32)are referredtoas"statically indeterminate see3.1.44).Themajority of applications are statically determinate.If determinacy is not known then anchors qualified for statically determinate useshouldbeselected.

Applications vulnerabletoprogressive collapse (including suspended ceilings, and suspended services such as pipework, ductwork or cable tray), and which do not satisfy the preconditions of multiple use, should be designed using anchors qualified for statically determinate use.

The specifier should determine the type of anchor to be specified, taking account of thefactorsdescribed in5.3.2 to 5.3.6,alongwiththe features and capabilities of the different anchor types as outlined in Annex C.

5.3.3Base material
BRITISH STANDARD
Not all anchors work in all base materials, so the specifier should ensure that the proposed anchors are suitablefor thebase material concerned. NOTEGuidanceon concrete is given in 5.3.3.2,and on masonry in5.3.3.3

5.3.3.2.1 Structural form
The specifier should evaluate thetype and strength of concrete structure,as there might be factors which could influence the choice of anchor or its positioning.

At the time of publication of this British Standard, it is expected that European Technical Approval Guidelines will be replaced by European Assessment Documents and European Technical Approvals will be replaced by European Technical Assessments upon implementation of EURegulation 305/2011(Construction Products Regulation)[2]in July2013

Structural dimensior
Specifiersshouldtakeinto accountthefollowingdimensionallimitationsofthe structure, as these limitations affect anchor performance.
a)Edgeandspacingparameters.
All anchors require an amount of the base materialaround them,to support the forces induced during their installation and/or those transferrec fromthe fixturein service.Datashould be acguired from themanufacturer identifying the edge distances and centre spacings that will provide full performance (characteristic edge distance, Cer or characteristic spacing, s.r), and absoluteminimum dimensions(minimumedge distance,Cminor minimum spacing, Smin), for which performance should be reduced accordin to the prescribed design model (see Figure 3). NOTE 1Anchors conforming to ETAG 001, Parts 1 to 5 ([8] and [11] to [14] will, depending on theiroption, include this data.Some options allow design using minimumdimensions, while others allow anchors tobe specified onlyat the critical distances with no closer dimensions allowed. There is, however, a relationship between the anchor spacing and the edge simultaneously with the minimum spacing, Smin. Minus tolerances should not be specified.
