Indian StandardSPECIFICATION FOR GAMMA-BHC (LINDANE)

EMULSIFIABLE CONCENTRATES

( Fourth Revision)

o. FOR E W 0 R D

0.1 This Indian Standard (Fourth Revision) was adopted by the IndianStandards Institution on 31 January 1978, after the draft finalized by thePest Control Sectional Committee had been approved by the Agriculturaland Food Products Division Council and the Chemical Division Council.

0.1 Gamma-BlfC ( Lindane) emulsifiable concentrate are widely used inthe control of pests of agricultural crops.

0.3 Gamma-BHC emulsifiable concentrate is generally manufactured to'contain 20 percent ( mlm ) of gamma-isomer.

0.4 This standard was first issued in 1956 as SHe (HeH) emulsifiableconcentrates. It was revised in 1958 to incorporate changes regarding thedetermination of gamma-Blf'C content in the formulation in order tospecify either the chromatographic or polarographic method. The secondrevision was issued in 1966 and the third revision in 1972. As now theCentral Insecticides Board (CIB) has approved this product to beformulated exclusively from Gamma-BHC ( Lindane), it is being alignedwith these requirements in the present version.

0.5 In the preparation of this standard, due consideration has been given tothe provisions of the Insecticides Act, 196s and the Rules framedthereunder. However, this standard is subject to the restrictions imposedunder these, wherever applicable.

0.6 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, express­ing the result of a test or analysis, shall be rounded off in accordance withIS: 2·1960·. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard prescribes the requirements and the methods of samplingand test for Garnma-BffC ( Lindane) emulsifiable concentrates.

2. REQUIREMENTS

2.1 Constituents - The material shall consist of Garnrua-Bbl'C ( Lindane)dissolved in suitable solventts), with emulsifying agent(s) and with andwithout stabilizer(s) and coupler(s).

2.1.1 Gamma-Btlt: ( Lindane), employed in the manufacture of thismaterial shall conform to IS: 882-1956*.

2.2 Physical - The material shall comply with the physical requirementsgiven in 2.2.1 to 2.2.5.

2.2.1 Description - The material shall be stable liquid free from extra­neous impurities and sediment, Suspended material shall be negligible. Itshall be free from odour of BHC.

2.2.2 Cold Test - No turbidity or separation of solid or oily materialshall occur when the concentrate is subjected to the cold test at 10°C asdescribed in 13.1 of IS:6940-1973t or any other lower temperature as agreedto between the purchaser and the supplier.

2.2.3 Flash Point (Abel) - When determined by the method describedin IS: 1448 [P:20 ]-1960:, flash point of the material shall be not below24·SoC.

2.2.4 Emulsion Stability - Any separation, including creaming at the topand sedimentation at the bottom, of 100 ml of emulsion prepared in stan­dard hard water with 5 ml of concentrate for public health use and with2 ml of cencentrate for agricultural use, shall not exceed 2 ml when testedby one of the methods prescribed in 13.3 of IS: 6940-1973t .

2.2.5 Heat Stability - After treating in accordance with the procedurein 13.4 of IS: 6940-1973t, the material shall comply with the requirementsof 1.2.1 to 2.2.4 and 2.3.1 of this specification.

2.3 Chemlcal- The material shall comply with the chemical requirementsgiven in 2.3.1 and 2.3.1.

2.3.1 Gamma-Isomer Content - When determined by the method pres-cribed in Appendix A of IS: 561-1978§ the observed Gamma-Isomer content,
