Snow Pillow Specifications

Snow pillow construction Snow pillows must be made of 60-millimeter polypropylene, or other material deemed to perform as well or better.

Size is 10 feet in diameter, as measured from the center of any of the six sides to the center of the opposite side. A pillow 10 feet in diameter is the SNOTEL standard.

The top of the pillow must be fitted with one each tank adapter, or equivalent, with plug.

The opposite sides of the threaded portion of the tank adapter will be cut or ground flat to a depth of three-eighths of an inch from the lip for approximately a half inch along the threaded shank. This provides two flat surfaces that can be gripped by a wrench to facilitate threading and tightening of external plumbing lines. It must be centered on the top of the pillow and be reinforced by two plies of 0.060 (units) polypropylene material.

The underside inlet must be fitted with one each tank adapter with rubber gaskets.

The opposite sides of the threaded portion of the tank adapter will be cut of ground flat to a depth of three-eights of an inch from the lip for approximately half an inch along the threaded shank. This provides two flat surfaces that can be gripped by a wrench to facilitate threading and tightening of external plumbing lines. This adapter is to be located on the bottom panel. Looking from top, the adapter will be located 14 inches in toward the center from a point on the edge which is 26 inches to the left from any corner.

All seams will be one and a quarter inches minimum scrim lap and seal, with seam flap sealed down on exterior seam edge. No seam should run parallel within 3 inches of any edge. There will be no loose exterior seam edges. Seams will be sealed dielectrically.

Corners are to be double-folded and double-sealed, diaper type. All exposed scrim and corners must be flood coated and sealed with polypropylene-45 based coating.

All seams must be inspected visually and any irregularities corrected.

Each pillow will be air-inflated to 0.25 psi for 12 hours. The entire surface area is to be sprayed or washed with a leak detection solution. No bubbles may appear on any surface or seam while the pillow is inflated. Any irregularities must be corrected.

Pillows will be folded and prepared for shipment using poly film between all folds and layers to minimize damage to the pillow during shipment.

A 4- by 4-inch block of Styrofoam will be securely taped over each tank adapter to minimize damage to the pillow during shipment.

The entire pillow will be encased in a layer of 0.020 (units) PVC or greater, and placed in a cardboard box no smaller than 32 by 32 by 10 inches. Each box will have sufficient wall thickness, durability, and construction to maintain its original shape and integrity during shipment.
