GUIDELINES FOR i, PROCUREMENT dF HIDES AND SKINi

./’ !

0. -FOREWO,RD z.

0.1 This Indian Standard was adopted’by theIndian Standards Institution on 11 February 1980, after the draft finalized by.the Leather Sectional Committee had been approved by the Chemical Division Council.

0.2 Hides and skins in India may be obtained from various sources, such as, (a) municipal slaughter houses; (b) private butchers; (c) flaying and carcass utilization centres; (d) pinjrupoles; and (e) village chamars. Most

!,sf* the ‘failen hides are obtained’ frum the last,three sources.

0.3 Raw hides and skins being natural products vary considerably in quality. depending on the zbteed of the animal.and on the climatic condi- tions prevailmg in different parts of the country. Most of the cattle hides in India are obtained from fallen animals and it is. well recognized that fallen hides are generally inferior in quality than slaughtered hides.

9 @at and sheep skins are: generally-: obtained from slaughtered animals but many of them are procured from the country side also.

0.3.1 In Northern India, city based raw hide, dealers collect hides and skins directly through their’ agents from the surrounding regions. But these, dealers d.o not ,have any facility for storing hides and skins under

” controlled conditions of temperature and humidity. Some of them trim 7 the cattle hides but some others do not trim at all. Hides and skins are

resalted by them if felt necessary and are classified into certain categories. Skins available’in Southern India are generaily sold by the primary producers in the weekly Mum&es and are procured directly by the tanneries or their agents an,d are resalted and classified by them according

‘i to their need.

0.35 No set procedures are uniformly followed in the raw hide and skin trade so as to facilitate the buyers for the procurement of their raw

:/. stock. Traditional methods based on experience are being followed and : 6 tanners face difficulties for, procuring raw hides and skins.

“0.4 Cdnsidering these difficulties experienced by the tanners, the Leather Sectional Committee decided to formulate this standard. It is expected to guide the raw hides and skins merchants or primary producers, raw hide purchasers or selectors and the tanners in procuring the material of known quality.

From the total lot offered for:sale, 10 percent of total pieces shall be selected for the purpose of examination by random sampling. To ensure randomness of selection random number tables ( SCE IS : 4905-19687 ) may be followed.

3.1.1 Flaying - Examine the samples for proper flaying. All hides or skins should be flayed properly ( whether in a slaughter house or by a private butcher/village chamar ) according to a standard procedure.

3.1.3 Hair&) - In case of green hide or skin examine whether it shows any hair-slip. Microbial action as well as autholytic enzymic action may result in hair-slip.
