British Standards

British Standards - legal status

British Standards and British Standard Codes of Practice do not have the force of law but they do represent best practice and may be referred to in a court of law in the event of an accident or building failure. It is therefore in the best interests of everyone involved in the use of fixings to follow their recommendations as far as possible.

The CFA has been involved in the development of most of the British Standards  and codes referred to here.

British Standards

BS 8539:2012 Code of practice for .......... anchors ....

BS 8539:2012 Code of practice for the selection and installation of post-installed anchors in concrete and masonry.

This British Standard (published in October 2012) is expected to change significantly the way anchors for safety critical applications are used from the specification through to commissioning and in the process to improve the level of safety and eliminate failures. To view a video introduction to the code click here.

The Code sets out the roles and responsibilities of all key stakeholders from the manufacturer through specifier and distributor to contractor, installer and tester.  

It includes best practice guidance on the selection and installation of fixings as the name implies and also on the methods by which anchors should be tested on site if that is needed in a CFA Guidance Note: Procedures for site testing construction fixings - 2012, which is a normative reference in the Code, i.e. it is effectively part of the BS.

Due to the complexity of the overall document the CFA has published a "CFA 8539 Toolkit" comprising series of 6 "CFA 8539 Forms" to help with the gathering and dissemination of information, 4 "How to . . . . . " guides for each of the four main stakeholders, 3 selected Guidance Notes and 2 ETAG selector Charts.

 

 

 

 

BS 5080

BS 5080-1:1993 Structural Fixings in concrete and masonry. Method of test for tensile loading.

BS 5080-2:1986 Structural Fixings in concrete and masonry. Method for determination of resistance to loading in shear. 

This BS comes in two parts and describes methods for the laboratory testing of construction fixings, primarily for the purposes of determining anchor performance.

These test methods are still current but have effectively been superseded. Laboratory testing for the determination of publishable values of anchor performance (normally in concrete) will usually be carried out according to the methods called up in the appropriate ETAG, see European Technical Approvals, below. Tests required for the determination of anchor performance for a specific project in base materials for which there is no manufacturer data available e.g. masonry of unknown strength, are recommended, by BS 8539, to be carried out to the test regimes called up in BS 8539 to the procedures described in CFA Guidance Note: Procedure for site testing construction fixings on site - 2012. The special recommendations of BS 5080 are usually impractical on construction sites. 

BS EN 795:2012

BS EN 795:2012

Protection against falls from a height - Anchor devices - Requirements and testing.

One of the testing categories recognised by the CFA is that of testing Safety Harness eyebolts or more correctly: Class A1 anchor devices according to BS EN 795. This standard is of little interest to anyone other than manufactures of fall arrest equipment but is the source document for BS7883 see below.

BS 7883:2005

BS 7883:2005

Code of Practice for the design, selection, installation  use and maintenance of anchor devices conforming to BS EN795.  (Amended August 2007).

This is the bible for companies involved in the installation or periodic examination (testing) of safety harness eyebolts made according to BS EN 795 for fall arrest or rope access purposes. Approved Testers accredited for this testing category will work to this standard.
