National Environmental Laboratory Accreditation Program (NELAP) is a non-profit organization that develops national consensus standards for environmental laboratory accreditation. States approve the standards for use in their jurisdiction and are responsible for their implementation.
NELAP enhances the quality of environmental laboratory in a cost-effective manner by applying appropriate standards. It was established in 1995 by the US Environmental Protection Agency (EPA) to cater the need of eradicating hazardous environmental waste and water waste. The process induced technological innovation and led to business revolution. NELAP process covers various sectors and is governed by the Environmental Laboratory Advisory Board (ELAB) that is a federal advisory committee.
Standards have been devised to provide guidance for the environmental laboratories as they engage in the production and testing of samples. In order to ensure safety and better quality of the products, The NELAP Institute (TNI) has developed a number of standards that abide by the global requirements and are aligned with the EPA guidelines.
Standards for testing of all medias such as hazardous waste, waste water, drinking water, air, soil etc are available under the EPA regulatory programs such as Clean Air Act (CAA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), and Safe Drinking Water Act (SDWA).
All these standards are practiced in various laboratories to ensure efficient and safe testing. These standards help focus on the minute details and opt for effective ways to promote environmental safety.
ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry (WDXRF). It provides rapid, multi-element determinations with sufficient accuracy to assure product quality.
The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum. The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding.
An immunological method for quantization of Hevea Natural Rubber (HNRL) proteins using rabbit anti-HNRL serum. Rabbits immunized with HNRL proteins react to the majority of the proteins present, and their sera have the capability to detect most if not all the proteins in HNRL.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment.
ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices (ECD) integrated in insulating glass units (IGU). This test helps to understand the relative serviceability of electrochromic glazings applied on ECD.
ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. This test method is useful in the acknowledgment of technical standards.
