(Second cover, Foreword, para 3) - Insert the following new clause:

.. A scheme for labelling environment friendly products known as Era Mark hasbeen introduced at the instance of the Ministry of Environment and Forests(MEF), Government of India. The ECO Mark would be administered by theBureau of Indian Standards (BIS) under the B15;Act, 1986 as per the ResolutionsNo. 71 dated 21 February 1991 and No. 425 dated 28 October 1992 published inthe Gazette of the Government of India. For a product to be eligible for markingwith ECO logo. it shall also carry the lSI Mark of BIS besides meeting additionaloptional environment friendly requirements. For this purpose, the StandardMark of BIS would be a single mark being a combination of the lSI Mark andthe ECO logo. Requirements to be satisfied for a product to qualify for the HISStandard Mark for ECa friendliness being included in the relevant publishedIndian Standards through an amendment, These requirements arc optional;manufacturing units are free to opt for the lSI Mark alone also.

The Amendment is based on the Gazette Notification No. 160dated 1 April 1999for Fire Extinguishers as environment friendly products published in the Gazetteof the Government of India.'I
