B181.3-99

1. Scope 1.1 This Standard provides requirements for polyolefin laboratory drainage systems from corrosive applications. Requirements for materials, pipe, and fittings are included. Note: Polyolefin includes both polyethylene and polypropylene plastics. 1.2 These requirements apply to pipe and fittings that are to be joined by heat fusion using the joining equipment supplied by the manufacturer. This Standard is not intended to provide for interchangeability between plastic pipe and fittings from different manufacturers, but it does allow for transition fittings for joining one manufacturer's product to another's, provided the joining technique used is other than heat fusion. 1.3 Systems having features differing from or additional to those contemplated by this Standard should be investigated to determine whether they comply with the intent of this Standard.
