The question that every quality manager in Malaysia should ask before accepting a calibration certificate is not whether the calibration was performed. It is whether the laboratory that performed it can prove, through independent third-party assessment, that it was performed correctly.
ISO/IEC 17025 accreditation exists precisely to answer this question. An accredited laboratory has been assessed by an independent body against the international standard for calibration laboratory competence and confirmed to meet it. The assessment covers not just technical capability but method validation, reference standard management, environmental controls, staff competence, measurement uncertainty calculation, and certificate documentation. When you receive a calibration certificate from an accredited laboratory, you are not trusting the laboratory’s self-assessment. You are relying on an independent assessment that has already been performed on your behalf.
Atlantic Services holds ISO/IEC 17025 accreditation under the SAC-SINGLAS scheme, which is the Singapore Accreditation Council’s laboratory accreditation programme. Our accreditation carries ILAC MRA recognition, meaning our certificates are accepted across all ILAC-member economies without the need for re-calibration or additional verification. For manufacturing companies, oil and gas vendors, and vessel operators in Malaysia who supply to Singapore-based principals, operate under international quality management frameworks, or have instruments inspected by international auditors, this recognition is directly relevant to the value of the certificates we issue. The guides in this category address the accreditation questions that serious buyers ask when evaluating a calibration provider: what SINGLAS accreditation covers, whether it is valid in Malaysia, how ILAC MRA works in practice, and what a compliant calibration certificate must contain to hold up under the audit scrutiny of a principal company or regulatory body.

Switching Providers and Managing the Transition: How to Change Without Creating Compliance Gaps For QA managers considering a provider change or managing calibration programme continuity
Switching calibration providers creates a transition risk if the handover is not managed carefully: instruments whose calibration history is held by the previous provider, certificate format differences that affect audit submission, and timing gaps between the last calibration by the previous provider and the first by the new one. These guides address how to manage a provider transition without creating calibration record gaps that attract audit findings.
