HAR §11-502-6. Sampling

(a) A certified inspector shall collect, in a statistically random manner that is representative of the homogeneous area, bulk samples from each homogeneous area of friable surfacing material that is not assumed to be ACM, and shall collect the samples as follows: (1) At least three bulk samples shall be collected from each homogeneous area that is one thousand square feet or less, except as provided in section 11-502-7(c)(2); (2) At least five bulk samples shall be collected from each homogeneous area that is greater than one thousand square feet, but less than or equal to five thousand square feet, except as provided in section 11-502-7(c)(2); and (3) At least seven bulk samples shall be collected from each homogeneous area that is greater than five thousand square feet, except as provided in section 11-502-7(c)(2). (b) Thermal system insulation shall be sampled as follows: (1) Except as provided in paragraphs (2) through (4) and section 11-502-7(c), a certified inspector shall collect, in a randomly distributed manner, at least three bulk samples from each homogeneous area of thermal system insulation that is not assumed to be ACM; (2) At least one bulk sample shall be collected from each homogeneous area of patched thermal system insulation that is not assumed to be ACM if the patched section is less than six linear or square feet; (3) In a manner sufficient to determine whether the material is ACM, at least three bulk samples shall be collected from each insulated mechanical system that is not assumed to be ACM where cement or plaster is used on fittings such as tees, elbows, or valves, except as provided by section 11-502- 7(c)(2); and (4) Bulk samples are not required to be collected from any homogeneous area where the certified inspector has determined that the thermal system insulation is fiberglass, foam glass, rubber, or other non-ACBM, and material is not multi-layered. (c) In a manner sufficient to determine whether material is ACM, an certified inspector shall collect at least three bulk samples from each homogeneous area of friable miscellaneous material that is not assumed to be ACM. (d) If any homogeneous area of nonfriable suspected ACBM is not assumed to be ACM, then a certified inspector shall collect, in a manner sufficient to determine whether the material is ACM, at least three bulk samples from the homogeneous area of nonfriable suspected ACBM that is not assumed to be ACM.
