Indian StandardSPECIFICATION FOR

WETTABLE SULPHUR POWDER

( Second Revision)

o. FOR E W 0 R D

0.1 This Indian Standard (Second Revivion ) was adopted by the IndianStandards 1nsutunon on 30 September 1982, after the draft finalized by thePest Control Sectional Committee had been approved by the Agnculturaland Food Products Divisron Council and the Chemical Division Council.

0.2 Wettable sulphur powder is largely used for the control of pests anddiseases in the field of agriculture.

0.3 Wettable sulphur powder is generally manufactured to contain 80percent ( mlm ; of sulphur.

0.4 This standard was first issued in 1965 and subsequently revised in 1975.Some of the requirements hke sulphur content and suspensibihty Werechanged through the Issue of three amendments. In the present revrsron,the various requirements have been reviewed in the light of experiencegained 10 the country. Opportunity has also been taken to refer IS:8190( Part I )-1980* for packing requlre!Uents.

O.~ In the preparation of this standard due consideration has been given tothe provisions of the Insecticides Act, 1968 and the Rules framed there­under. However, this standard is subject to the restrictions imposed underthese, wherever applicable.

0.6 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, expressIngthe result of a test or, analysis, shall be rounded off in accordance withIS:2-1960t. 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 wettable sulphur powder.

-Requirements for packing of pesticides: Part I Solid pesticides ( first revision ).tRules for rounding off numerical values (re¥istld).

3

IS : 3383 - 1982

2. REQUIREMENTS

2.1 Description - The material shall be in the form of a homogeneouspowder, pale yellow to brownish In colour, and shall wet readily on mixingwith water, providing a suspension suitable for use as a.spray.

2.2 The material shall also comply with the requirements given in Table I.

IS: 3383 - 1982

2.1.1 Sulphur Content - When determined by the method prescribed inAppendix A, tbe observed sulphur content, percent (m/m), of any of thesamples shall not differ from the declared nommal value by more than thepercent tolerance lmuts Indicated below:

Nominal Value, Percent Tolerance) Percent

up to 9 +105

Above 9 and below 50 ± 5of the nominalvalue

50 and above + 53

2.2.1.1 The actual value of sulphur content in the formulation shall becalculated to the second decimal place for rounding off to the first decimalplace before applymg the tolerances given in 2.2.1.

2.2.1.2 The average content of all the samples shall not be lower thannomrnal content.

3. PACKING AND MARKING

3.1 Packing - The material shall be packed as per requirements given In18:8190 (Part 1)-1980·.

3.2 The container shall hear legibly and indelibly the following Informationand any other information as required under the Insecticides Act and Rules:

a) Name of the material;b) Name of the manufacturer;c) Date of manufacturer;d) Batch number;e) Net mass of contents;f) Nominal sulphur content, percent ( mJm ); andg) The cautionary notice worded as in Insecticides Act and Rules.

3.1.1 Each container may also be marked With the IS[ Certification Mark.NOTE-The use of thl' lSI Ceruficauon Mark IS governed by the provisions of

the Indian Standards Institution (Certification Marks) Act and the Rules andRegulanons made thereunder. The 151 Mark on products covered by an IndianStandard conveys the assurance that they have been produced to comply withthe requirements of that standard under a well-defined system' of inspecuon,testmg and quality control which IS devised and supervised by lSI and operatedby the producer. 151 marked products are also continuously checked by lSI forconformity to that standard as a further safeguard. Details of conditions underwhich a licence for the use of the lSI Certification Mark may be grantedto manufacturers or processors, may be obtained from the Indian StandardsInstitution.

*Requlremenls for packing of pesticrdes: Part 1 Solid pesticides ( first revision ).

IS: 3383 - 1982

4. SAMPLING

4.1 Representative samples of the material shall be drawn as prescnbed in'Indian Standard methods for sampling of pesticides and their formulations'(under preparation).

NOTE - Till such time the standard under preparation 1\ published samples shallbe drawn as agreed to between the concerned parties.

5. TESTS

5.1 Tests shall be carried out by the prescribed methods referred to In

col 4 and 5 of Table 1.

5.2 Quality of Reagents - Unless specified otherwise, pure chemicals anddistilled water (see IS: 1070-1977* ) shall be employed In tests.

NOTB- 'Pure chemicals' shall mean chemicals that do not contain impunnes whichaffect the results of analysis.

APPENDIX A

[ Clause 2.2.1 and Table 1, item (i) ]

DETERMINATION OF SULPHUR CONTENT

A-O. PRINCIPLE OF THE METHOD

A-O.I The sulphur present in the formulauon IS converted to thiosulphateand then determined rodrmetncally,

A-I. REAGENTS

A-I.l Sodium Sulphite - crystalline.

A-I.l Liquid Paraffin

A-I.3 Formaldehyde - 40 percent ( vlv ).

A-l.4 Acetic Acid Solution -20 percent ( vlv).

A-I.S Standard Iodine Solution - 0'1 N, freshly prepared.

A-I.6 Starch Indicator Solution - O'S percent. freshly prepared.

A-I.7 Carbon Tetrachloride

*SpeclficatloD for water, distilled quality ( revised).

6

IS: 3383 -1982

A-2. PROCEDURE

A-2.t Weigh accurately sufficient quantity of the sample to contain 0·1 g ofsulphur and transfer it to a Erlenmeyer flask, add 30 to 40 ml of water, 2 gof sodium sulphite and about 1 to 2 ml liquid paraffin.

A-I.I Attach the condenser, Warm gently until the sulphur has dissolved,then boil it for 40 minutes, cool and remove the condenser. Add 10 ml offormaldehyde, 10 ml of acetic acid and 25 ml of carbon tetrachloride to thesolution to remove the paraffin. TItrate immediately with the standardiodine solution using starch solution as indicator.

A-I.3 Carry out a blank determination on the reagents.

A-3. CALCULATION

A-3.t Sulphur content, percent by mass

where

0'03206 (v-V) N X 100m

v = volume, in ml, of the standard iodine solution required for thetest with the material ( see A-I.2 );

V = volume, in ml, of the standard iodine solution required for theblank determination (see A-2.3 );

N = normality of the standard iodine solution; and

m = mass, in g, of the sample taken for the test.

APPENDIX B

[ Table 1; item (v) ]

DETERMINATION OF ARSENIC

B-O. METHOD

B-o.t For the determination of arsenic (as As) the modified Gutzeitmethod as prescribed in IS: 2088-1971* shall be followed. The procedurefor the preparation of the solution for the test method shall be as prescribedin B-1.

·Metbods for determination or arsenic ( first revision ).

7

IS: 3383 -1982

B-1. PREPARATION OF THE SOLUTION

B-I.I Weigh 10 g of the material into a 500-ml KjeldahI flask. Add 40 mlof a mixture of 2 volumes of bromine and 3 volumes of carbon tetrachlo­ride, and allow the flask to stand for 30 minutes with occasional shaking.Add 50 ml of arsenic-free concentrated mtric acid, dropwise, SWirlingthe flask continuously, and occasionally putting into an ice-bath to prevent, Icr-heating and excess fumes. If any unoxidized sulphur remains at theend of this treatment, add again 5 ml of bromine-carbon tetrachloridemixture and 10 ml of nitric acid. When all the sulphur is oxidized tosulphuric acid, place the flask on a steam-bath to drive off the bromine andcarbon tetrachlorrde slowly, and then on a hot-plate until fumes of sulphurtrioxrde are evolved. If the resulting solution is not colourless, cool, add10 ml of nitric acid, and repeat the evaporation on the hot-plate unnlfumes of sulphur trioxide are evolved. Finally, cool the solution, add50 ml of water, and evaporate to fumes of sulphur trioxide. Usually twoor three additions of water with subsequent evaporation are necessary toremove the last traces of nitric acid from the sulphuric acid formed.
