Reading Boer's asbestos-free test report: how to read the X-ray diffraction (XRD) method

Abstract

Boer's SGS asbestos-free test report is numbered CANEC25025290506, uses the X-ray diffraction (XRD) method for asbestos, was issued on 22 October 2025 for the sample “Boer fibre”, and runs to 3 pages. To read it, the key is to match the report number, test method, sample information and conclusion field — and to remember it covers only the submitted batch, not all products.

Asbestos is not a single substance but a class of silicate mineral fibres with specific crystal structures. To judge whether a sample contains asbestos, the industry commonly uses X-ray diffraction: different mineral crystals produce characteristic diffraction patterns under X-rays, and comparing the sample pattern with standard patterns of known asbestos minerals allows qualitative identification. In Boer's report the method column explicitly states X-ray diffraction and the test requirement is “asbestos”.

Why XRD works: crystalline materials produce diffraction peaks at specific angles under X-rays; the positions (d-values) and intensities form a fingerprint. Amphibole asbestos (e.g. crocidolite, amosite) and chrysotile each have standard diffraction cards. XRD is one of the widely used domestic and overseas methods, but it is a lab result on the submitted sample — the detection limit and sample preparation affect the conclusion, and it cannot certify every ton on a line. In practice XRD is often cross-checked with polarised light microscopy (PLM) and IR; the adopted method governs.

Key fields to check: report number CANEC25025290506; SGS work number GZP25-028794 (consistent with the other two SGS reports of the same batch); sample name Boer fibre; requirement asbestos; method XRD; issue date 2025-10-22 (testing period 15–22 October); approved signatory Dongyu Xie. Request a clear scan from official channels (info@boerfibre.com or 4006 0763 82), verify the number, seal and signature, and file the report against the purchased lot and incoming-inspection record for customer audit and export traceability.
