29、o address all the safety problems associated with its use. It is the responsibility of the user of the standard to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use. Unused synthetic esters which are the subject of this standard
30、should be handled with due care with regard to personal hygiene. Direct contact with eyes may cause slight irritation. In the case of eye contact, irrigation with copious quantities of clean running water should be carried out and medical attention sought. Some of the tests specified in this standar
31、d involve the use of processes that could lead to a hazardous situation. Attention is drawn to the relevant standard for guidance. Environment The disposal of synthetic esters, chemicals and sample containers mentioned in this standard should be carried out in accordance with local regulations with
32、regard to their environmental impact. Precautions should be taken to prevent the release of synthetic esters into the environment. BS EN 61099:2010 6 61099 IEC:2010 INSULATING LIQUIDS SPECIFICATIONS FOR UNUSED SYNTHETIC ORGANIC ESTERS FOR ELECTRICAL PURPOSES 1 Scope This International Standard cover
33、s the specification and test methods for unused synthetic organic esters. It applies to synthetic organic esters, delivered to the agreed point and time of delivery intended, for use in transformers, switchgear and similar related equipment in which synthetic organic esters are required as an insula
34、nt and for heat transfer. These unused synthetic organic esters are obtained by chemical processing and physical treatments of fatty acids and polyols. NOTE Maintenance of synthetic organic esters in equipment is covered in a separate standard (IEC 61203). 2 Normative references The following refere

42、organic esters liquid based on synthetic organic esters as delivered by the supplier 3.2 additive suitable chemical substance/s which is/are deliberately added to a synthetic organic ester in order to improve certain characteristics, e.g. pour point, viscosity, foaming, oxidation stability NOTE If a
43、dditives are used, these should be mentioned by the supplier to the user, if requested. This may involve issues of confidentiality in an agreement. Additives, if used, need to comply with local regulations. 4 General remarks The unused synthetic organic esters to which this standard applies are liqu
44、ids which contain only carbon, hydrogen and oxygen. They are prepared from mono- or polyhydric alcohols and mono- or polybasic aliphatic or aromatic acids. Commercial products may be based on single esters or a mixture of esters and may contain oxidation inhibitors and other additives. Unused synthe
45、tic organic esters selected for use in transformers have high flash and fire points and are therefore relatively difficult to ignite. They may, however, have slightly higher viscosities than mineral insulating oils. Unused synthetic organic esters are more hygroscopic than mineral oils and this aspe
46、ct will need to be considered in their use and maintenance. NOTE Such a liquid, by definition, has not been used in, nor been in contact with, electrical equipment or other equipment not required for manufacture, storage or transport. The manufacturers and suppliers of unused synthetic organic ester
47、s will have taken all reasonable precautions to ensure that the liquid is not contaminated with polychlorinated biphenyls or terphenyls (PCB, PCT); used, reclaimed or dechlorinated oils; or other contaminants. BS EN 61099:2010 8 61099 IEC:2010 5 Health, safety and environment (HSE) properties (liqui
48、d properties related to safe handling and environment protection) 5.1 Flash point and fire point The safe operation of electrical equipment requires an adequately high fire point that is measured in accordance with ISO 2592 (Cleveland open cup). Flash point is measured with ISO 2719 (Pensky-Martens
49、closed cup procedure). 5.2 Biodegradation Unused synthetic organic esters as supplied in electrical applications are of interest because of their higher fire points and better environmental compatibility, relative to petroleum derived insulating mineral oil. Specific tests need to be undertaken to demonstrate biodegradability of these liquids. Tests include OECD 301 / OPPTS 835.3110 (US EPA). The biodegradability of unused synthetic ester fluids can be class
