CRSC · California Referenced Standards Code

Testing, laboratory approval, inspections and performance testing

The CRSC sets test procedures, report requirements, laboratory approval/accreditation and inspection/labeling rules to verify materials, products and assemblies meet California standards.

Last reviewed: July 6, 2026

Overview

This part of the California Referenced Standards Code (CRSC) governs how products, assemblies and systems are tested, how testing laboratories are approved, and how inspection, labeling and performance verification are documented and enforced. It includes endurance and performance test procedures (for example § 12-10-204 and § 12-10-304), which set test methods, cycle and emergency-operation requirements, and required contents of test reports .

The CRSC ties into California’s building and fire codes for approval and acceptance: approved independent agencies and laboratories must provide objective test reports and follow calibration, personnel and independence standards described in California Building Code Section 1703, and labeled products must be supported by representative testing and periodic inspection by the approved agency . Laboratory approval and manufacturer certification processes (including accreditation requirements) and inspection authority are established in the CRSC (see § 12-13-1554, § 12-13-1557 and § 12-13-1558) .

Key practical points: test reports must describe the sample, materials and test setup, be verified by the testing laboratory or qualified engineer, and show that representative production samples meet the standard; some standards require long cycle testing or specific emergency-operation tests (e.g., 100,000 cycles or defined force/load conditions) and permit use of listed components when appropriate . Laboratories are subject to approval criteria and, for many programs, accreditation (NVLAP or equivalent) before their results are acceptable for certification and labeling .

  • CRSC § 2.1 Medium relevance — show source text

    Chronological records and reports of annual inspections, audits and post-event inspections and documentation of equipment or structural changes shall be maintained.

    Records shall be indexed and be readily accessible to the Division (see 2 CCR Section 2320 (c) (2)) [2.1].

    3102F.1.5 Baseline assessment. If “as-built” or subsequent modification drawings are not available, incomplete or inaccurate, a baseline inspection is required to gather data in sufficient detail for adequate evaluation.

    The level of detail required shall be such that structural member sizes, connection and reinforcing details are documented, if required in the structural analysis. In addition, the strength and/or ductility characteristics of construction materials shall be determined, as appropriate. Nondestructive testing, partially destructive testing and/or laboratory testing methods may be used.

    MARINE OIL TERMINALS

    All fire, piping, mechanical and electrical systems shall be documented as to location, capacity, operating limits and physical conditions in the equipment layout diagram(s).

    3102F.2 Annual compliance inspection. The Division may carry out annual inspections to determine the compliance status of the MOT with this code, based on the terminal’s audit and inspection findings and action plan implementation (see Section 3102F.3.9).

    These inspections may include a visual and tactile assessment of structural, mechanical and electrical systems of the topside and underside areas of the dock, including the splash zone. Subject to operating procedures, a boat shall be provided to facilitate the inspec- tion of the dock undersides and piles down to the splash zone.

    3102F.3 Audits.

    3102F.3.1 Objective. The objective of the audit is to review structural, mechanical and electrical systems on a prescribed periodic basis to verify that each berthing system is fit for its specific defined purpose. The audit includes above water and underwater inspec- tions, engineering evaluation, documentation and recommended follow-up actions.

    3102F.3.2 Overview. The audit shall include above water and underwater inspections, and structural, electrical and mechanical systems evaluations, with supporting documentation, drawings and follow-up actions. Structural systems shall include seismic, oper- ational, mooring, berthing and geotechnical considerations. Mechanical systems shall include fire, piping/pipelines and mechanical equipment considerations. The audit is performed by a multi-disciplinary team of engineers, qualified inspectors and may include Division representatives.

    The above water inspection involves an examination of all structural, mechanical and electrical components above the waterline. Structural defects and their severity shall be documented, but the exact size and location of each deficiency is typically not required.

    The underwater inspection involves an examination of all structural, mechanical and electrical components below the waterline. A rational and representative underwater sampling of piles may be acceptable with Division approval, for cases of limited visibility, heavy marine growth, restricted inspection times because of environmental factors (currents, water temperatures, etc.) or a very large number of piles.

    Global operational structural assessment rating(s) (OSAR), global seismic structural assessment rating(s) (SSAR) and global inspection condition assessment rating(s) (ICAR) shall be assigned to each structure and overall berthing system, where appropriate (Table 31F-2-4).

  • CRSC § 73.4 Medium relevance — show source text

    A manufacturer may appeal the Executive Director’s determination to the full Commission.

    1. Thermal performance of building insulations shall be stated in R value. Other insulations shall use thermal conductivity, conductance or R value as appropriate.

    2. All thermal performance tests shall be conducted on materials which have been conditioned at 73.4° ± 3.6°F and a relative humidity of 50 ± 5 percent for 24 hours immediately preceding the tests. The average testing temperature shall be 75° ± 2°F with at least a 40°F (4°C) temperature difference.

    3. Aluminum foil insulation shall be tested according to ANSI/ASTM C236-66 to determine the thermal performance in horizontal, upward and downward directions. The tested thermal performance in the heat-flow direction or directions of the intended application shall be labeled on the material. The manufacturer shall test once in each direction of intended application, except that for products labeled with only one heat-flow direction, the manufacturer shall test two samples in that direction.

    4. Insulation (other than aluminum foil insulation materials) for which additional value is claimed for facings and air spaces shall be tested for thermal performance as a material without the air space pursuant to this article. The manufacturer may elect to report additional thermal performance values of a given construction tested according to ANSI/ASTM C236-66 for that construction as long as full details of that construction are also disclosed in the certification statement and pursuant to Section 1557 (c) of this article. If a manufacturer elects to report a thermal performance value for a material plus an air space (as supplemental information to the required material thermal performance), but not necessarily for a full construction, the manufacturer must also disclose the conditions of the test and the limitations to the attainment of that result.

    5. Except as provided in Items 5 and 6, the thermal performance test results certified under Section 1555 of this article shall be the average of the values obtained from at least three tests.

    6. The average measured thermal performance of the tests required by Items 5, 6 and 7 shall not be more than 5 percent below the value specified on the product. In addition, all insulation material sold within the state after September 22, 1981, shall have a measured thermal performance not more than 10 percent below the value specified on the product.

    7. All numbered test descriptions shall be contained in the document “Test Descriptions for Insulating Material” dated February 27, 1981.

    on Jul 18, 2025 11:14 AM (CDT) THEREUNDER.

    STANDARDS FOR INSULATING MATERIAL

    1. Facings on representative samples may be removed or modified by slitting for the ANSI/ASTM C177-76 and ANSI/ASTM C518-76 tests.

    2. All thermal performance testing equipment used for testing insulating materials shall be calibrated with samples referenced to the United States National Bureau of Standards.

    3. Manufacturers of loose fill insulations for which no settled density test is required by this section shall be required to include the installed design density in the identifying information described in Section 1557. The manufacturer shall provide sufficient documentation to establish a valid basis for the determination of installed design density. The Executive Director shall determine whether a valid basis exists for the installed design density claimed by the manufacturer. If it is determined that a valid basis does not exist, the director may assign an appropriate installed design density or may require an appropriate test to determine the installed design density. The manufacturer may appeal the Executive Director’s determination to the full Commission.

Frequently asked questions

Who approves testing laboratories for CRSC work?

Laboratories are approved under the CRSC’s laboratory-approval procedures and—where specified—must be accredited by the U.S. National Voluntary Laboratory Accreditation Program (NVLAP) or meet the Commission’s approval criteria; see § 12-13-1554 for the approval and accreditation requirements .

What must a test report contain to support approval or listing?

Required contents include a detailed product description, drawings and photographs, identification and source of materials, test procedures and results (including pre- and post-test dimensions where relevant), installation instructions, and verification by the laboratory or qualified engineer; these requirements are set out in the CRSC endurance and performance test sections such as § 12-10-204 and § 12-10-304 .

How do inspections, labeling and follow‑up work for labeled products?

An approved agency must test representative samples and perform periodic inspections (including in-plant when necessary) to verify that labeled products remain representative of the tested samples; building officials rely on approved-agency reports (CBC § 1703) and the CRSC describes identification, labeling and inspection access for regulated products (e.g., §§ 12-13-1557–1558) .
