FORWARD The product certification scheme of the Bureau of Indian Standards, now under Bureau of Indian Standards Act 1986, is in operation, for more than four decades covering a wide variety of products. The wide experience in the area has bought a fair amount of rationalization in the certification process. This has resulted in the formulation of the Operation. Manual for Product Certification ( referred to as OMPC in this Manual) prescribing rules and practices generally applicable to all products. Products related rules/ guidelines are periodically issued to cover the specific requirement of different products. Still in view of the wide spread of the certification operations, differences are found in the application of these guidelines in the BIS certification offices in different parts of the country. Therefore, it has been decided to bring out sectoral manuals as guideline documents covering certification requirements of specific products/ group of products. This manual one in the series has been prepared to ensure uniformity in the certification practices in respect of Foam making Branch pipe , and Foam Inductor covered by IS 2097 The manual is strictly an internal document intended for use by the certification marks offices of BIS In this manual, some useful information relating to the products characteristic , a few design aspects, limitations and constraints in its use, which is considered useful to the user, are included in a brief manner. This manual takes into consideration the generally acceptable practices. This document is intended for internal use by BIS inspecting officers who should however do not treat such document as replacement for referred standards or that of relevant scheme for testing and inspection ( STI) Standards and other documents (STI etc) referred are as applicable at the time of preparation of manual. However, latest Standards/ other documents as implemented shall be referred. All effort has been made to incorporate details as per the latest version of the standard. However as the standard are dynamic and subject to amendments and revisions, users are encouraged to check the latest version of the respective methods of test subsequent to issuance of the issue of the manual, before using the information contained herein.

• SECTION I PRODUCT DESCRIPTION

• Description of Products:

1.1 Foam making branches provide one of the means for the production of mechanical foam, which is used for fighting fires in flammable liquids. Similarly Mechanical foam is also used to cover flammable liquid spills to prevent ignition. These branches work on self- aspirating principle in which air is induced into the stream of Water foam solution by the suction effect created at the water head in the branch during discharge of solution under pressure. IS 2097: 2012 lays down (the requirements regarding material and performance of the three types (as per the flow capacity) of foam making branches, that is FB 5X (225 lpm), FB l0X (450 lpm) and FB 20X (900 lpm) and inline foam inductor. The main use of Foam Making Branch Pipe, and Foam Inductor is for firefighting purposes.

1.2 Foam making branch pipes shall be designed for the generation of mechanical foam from the foam compounds conforming to IS 4989. These shall consist of three principal parts as indicated in Fig. 1. The FB 10X and FB 20 X models may be of jet or jet/spray type design. For the FB 5X type foam making branch, a stopcock capable of stopping the waterunder working pressure and a control valve of controlling the water discharge, may be provided, as given in Fig. 1A.

1.3 The FB 5X, FB 10X and FB 20X type foam making branch, which have plain jet type discharge, can be of different designs as shown in Fig. 1B. These designs are only indicative, and as performance parameters are prescribed, the design can be of any suitable type which meets the performance requirements. For the FB 20X branch, the holding arrangement shall be such so as to facilitate operation by two operators simultaneously.

1.4 For FB 10X and FB 20X jet/spray type branches, the design shall be as given in Fig. 1C. The holding arrangement shall be such that the operator/operators holding the branch can easily operate the jet/spray change over mechanism.

Incoming Raw materials (Ingots and sheets) received at the stores are forwarded to the inspection department. The ingots are further sent for casting(Control Valve, Water head with Discharge Nozzle, Foam compound inlet and Stop cock)and sheets are further send for forming by metal spinning for manufacturing Mixing tube and Discharge tube. The castings produced are inspected visually and dimensionally. Accepted castings parts are processed for machining, while the parts rejected are sent back to the foundry for melting & recasting, . After machining the Control Valve, Water head with Discharge Nozzle, Foam compound inlet and Stop cock are inspected visually, dimensionally. Formed (Mixing tubes and Discharge tubes) are inspected visually and dimensionally. The accepted parts are sent for assembly.

Assembly is carried out with proper assembly procedures. Assembled parts are then checked for dimensional operational and performance parameters. Foam making Branch Pipe and Foam Inductor passed are further sent for painting and marking. After marking the Foam making Branch Pipe and Foam Inductor are sent back to stores with ‘Inspected OK’ tag from where it will be packed in plastic bag and then inserted in corrugated box with packing list. After packing it is sent for dispatching.

• 6.0 Infrastructure for Production For manufacturing of Foam making Branch pipe and Foam Inductor the following infrastructure is required
