Type of Standards


timber and timber products (other than for composite board products and timber products that fall within the scopes of BOS 204-1, BOS 204-2, SANS 753 and BOS 176), that have a predicted service life at various levels of preservative treatment which are considered to be acceptable for a range of hazard conditions. This standard is not applicable to treatment with fire retardants or to treatments aimed at improving the physical properties of timber and timber products nor does it cover the inherent quality of timber or timber products or properties other than in respect of preservative treatment. NOTE 1 Except under the certification mark scheme, assessment of conformity with the requirements of 4.1, 4.3, 4.4 (in the cases of Class C and Class W preservatives), 4.6 (except where quantitative analysis has been agreed upon) and 4.7 requires special agreement between the supplier and the purchaser. NOTE 2 Where Class W preservatives have been used, previous grading of timber in respect of moisture content, splits, checks, warp, dimensions and finish may be invalidated. NOTE 2 This standard should be read in conjunction with BOS 174.

The Botswana Bureau of Standards (BOBS) understands the importance of impartiality and confidentiality in carrying out its management system certification activities. BOBS management is committed to gaining and maintaining the reputation, credibility and ultimately, confidence of its stakeholders in rendering its certification services. 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.
