Description

This standard specifies requirements for preservative-treated softwood poles, droppers, guardrail posts and spacer blocks. The poles are intended for the erection of fences and vine trellises, for general use in orchards
and for structural purposes. The droppers are intended for fencing. The posts and spacer blocks are intended
for the erection of steel guardrails at the sides of roads.
Timber used in ground contact and exterior above ground contact, should have an expected lifespan of at least
20 years when treated in accordance with the requirements applicable to the exposure classes (see table 3).
Timber treated for interior above ground exposure class should have an expected life span equal to that of the
structure it is used in.
NOTE 1 Except under the certification mark scheme, assessment of compliance with the requirements of 5.2
to 5.6 (inclusive) and, except in the case of units treated with creosote or a creosote and waxy oil mixture, 4.4,
requires special agreement between the supplier and the purchaser.
NOTE 2 Steps should be taken to prevent the “mushroom top phenomena” (cutting of wire into the pole) in
poles to be used as straining poles, as in vineyards.

Additionally, BOBS strives to continuously manage foreseen potential conflicts of duty and interest and ensures objectivity of its activities under the management system certification. To achieve the above, BOBS shall identify, analyse, record and manage potential conflict of duty and interest to ensure that certification services are not provided within relationships that have been identified to pose an unacceptable threat to impartiality. An Impartiality Committee shall periodically review activities of the certification function to verify commitment to credibility and fairness. The Committee shall further assist in the development of policies relating to impartiality of providing certification activities. BOBS is committed to maintaining in strict confidence all information accessed while rendering the certification services and shall ensure that such information is not divulged to third parties without the Client’s written consent unless if required by law.
