However, this standard issubjected to restrictions imposed under the Act and Rules wherever applicable. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of atest or analysis, shall be rounded off in accordance with IS2:1960 ‘Rules for rounding off numerical values (revised)’. The number ofsignificant places retained inthe rounded off value should be the same as that of the specified value in this standard. 4, --l Is 14934:2001 _— _- Indian Standard OXYFLUORFEN TECHNICAL — SPECIFICATION ,% I 1 SCOPE 4 PACKING \ This standard prescribes the requirements and the The material shall be packed in mild steel drum methodsofsamplingandtestforoxyfluorfentechnical. suitably lacquered with epoxy resin from inside.
