Option D—Narrow Fabrics Your Alert Profile lists the documents that will be monitored. For other specimens, multiply the length by the width. Competent statistical assistance is recommended for the investigation of bias. Fabric mass is also sometimes expressed inversely as linear metres per kilograms yards per pound with the fabric width stated.

The last option is Option D which is intended for use with narrow fabrics as so designated by the trade.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Take a minimum of three such laboratory samples from different places, distributed as evenly as practicable along the length of the roll or piece. It may be impractical to condition the specimens in Option A or nonconditioned d776 may be agreed upon by the purchaser and supplier.
