It is the UK implementation of CEN/TS
3、15590:2007. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature. It should be applied on this provisional basis, so that information and experience of its practical application can be obta
4、ined. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion to a European standard. A review of this publication will be initiated not later than 3 years after its publication by the
5、 European organization so that a decision can be taken on its status. Notification of the start of the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will dec
6、ide whether to support the conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it. Comments should be sent to the Secretary of the responsible BSI Technical Committee at British Standards House, 389 Chiswick High Road, London W4 4AL. The UK participa

Spontaneous combustion can occur wh
21、en SRF from municipal solid waste or biomasses are stored and/or transported. The microbial activity, because of aerobic degradation of easily degradable organic matter, acts as a primer causing the waste temperature to increase until autoxidation and the self-combustion processes takes place. The p
22、otential self-heating of SRF can be indirectly measured by the real dynamic respiration index (RDRI), which determines the extent to which easily biodegradable organic matter of a SRF has decomposed. Therefore, the RDRI identifies the actual point reached in the decomposition process and represents
23、a gradation on a recognized scale of values, which thus enables a comparison of potential self-heating.

24、pecifies a method to determine the current rate of potential microbial self- heating of a solid recovered fuel. The methods indirectly estimate the potential risk of microbial self-heating, odour production, vector attraction etc. The current rate of biodegradation can be expressed in milligrams O2
